This extension defines a generic container for data, called an Atom, +and several basic Atom types which can be used to express structured data. +Atoms allow LV2 plugins and hosts to communicate, process, serialise, and store +values of any type via a generic mechanism (e.g. ports, files, networks, +ringbuffers, etc.). Atoms are, with one exception, Plain Old Data (POD) which +may safely be copied (e.g. with a simple call to memcpy).

+ +

Since Atom communication can be implemented generically, plugins that +understand some type can be used together in a host that does not understand +that type, and plugins (e.g. routers, delays) can process atoms of unknown +type.

+ +

Atoms can and should be used anywhere values of various types must be stored +or transmitted. This extension defines port types, atom:ValuePort and +atom:MessagePort, which are connected to an Atom. The atom:Sequence type in +conjunction with atom:MessagePort is intended to replace the LV2 event extension.

+ +

The types defined in this extension should be powerful enough to express +almost any structure. Implementers SHOULD build structures out of the types +provided here, rather than define new binary formats (e.g. use atom:Object +rather than a new C struct type). New binary formats are an +implementation burden which harms interoperabilty, and should only be defined +where absolutely necessary.

+ +

Implementing this extension requires a facility for mapping URIs to +integers, such as the LV2 URID +extension.

Abstract base class for all atoms. An LV2_Atom has a 32-bit +type and size followed by a body of size +bytes. Atoms MUST be 64-bit aligned.

All concrete Atom types (subclasses of this class) MUST define a precise +binary layout for their body.

+ +

The type field is the URI of an Atom type mapped to an integer. +Implementations SHOULD gracefully ignore, or pass through, atoms with unknown +types.

+ +

All atoms are POD by definition except references, which as a special case +have type = 0. An Atom MUST NOT contain a Reference. It is safe +to copy any non-reference Atom with a simple memcpy, even if the +implementation does not understand type. Though this extension +reserves the type 0 for references, the details of reference handling are +currently unspecified. A future revision of this extension, or a different +extension, may define how to use non-POD data and references. Implementations +MUST NOT send references to another implementation unless the receiver is +explicitly known to support references (e.g. by supporting a feature).

The body of an LV2_Atom_String is a C string in UTF-8 encoding, i.e. an +array of bytes (uint8_t) terminated with a NULL byte +('\\0').

+ +

This type can be used for free-form strings, but in most cases it is better to +use atom:Literal since this supports a language tag or datatype. Implementations +SHOULD NOT use atom:String unless translating the string does not make sense and +the string has no meaningful datatype.

A UTF-8 encoded string literal, with an optional datatype or language.

+ +

This type is compatible with rdf:Literal and is capable of expressing a +string in any language or a value of any type. A Literal has a +datatype and lang followed by string data in UTF-8 +encoding. The length of the string data in bytes is size - +sizeof(LV2_Atom_Literal), including the terminating NULL character. The +lang field SHOULD be a URI of the form +<http://lexvo.org/id/term/LANG> where LANG is an ISO 693-2 or ISO 693-3 language code.

+ +

A Literal may have a datatype OR a lang, but never +both.

For example, a Literal can be "Hello" in English:

+
+void set_to_hello_in_english(LV2_Atom_Literal* lit) {

A homogeneous series of atom bodies with equivalent type and size.

+ +

An LV2_Atom_Vector is a 32-bit elem_count and +elem_type followed by elem_count atom bodies of type +elem_type. The element type must be a fixed size atom:Atom type, +i.e. the size of each element is the vector's size / +elem_count.

+ +

For example, an atom:Vector containing 42 elements of type atom:Float:

+
+struct VectorOf42Floats {

This is an abstract port type with incomplete semantics which can not be +used directly as a port type. Atom ports should be either a atom:ValuePort or +a atom:MessagePort.

+ +

Before calling a method on a plugin that writes to an AtomPort output, the +host MUST set the size of the Atom in that output to the amount of available +memory immediately following the Atom header. The plugin MUST write a valid +Atom to that port; leaving it untouched is illegal. If there is no reasonable +value to write to the port, the plugin MUST write null (the Atom with both +type and size 0).

An AtomPort that contains a persistent value. A value is +time-independent and may be used numerous times. A ValuePort is pure in +the sense that it may affect output but MUST NOT affect persistent plugin state +in any externally visible way.

+ +
    +
  • If a plugin has fixed values for all inputs, all ValuePort outputs are also +fixed regardless of the number of times the plugin is run.
    • + +
  • If a plugin has fixed input values for all ports except a ValuePort, each +value of that port corresponds to a single set of values for all +ValuePort outputs.
    • + +
  • If the plugin saves state other than port values (e.g. using the LV2 State extension), changing only +the value of a ValuePort input MUST NOT change that state. In other words, +value port changes MUST NOT trigger a state change that requires a save.

Value ports are essentially purely functional ports: if a plugin has only +value ports, that plugin is purely functional. Hosts may elect to cache output +and avoid calling run() if the output is already known according to these +rules.

Intuitively, a MessagePort contains a message or event which +is reacted to once (not a value which is computed with any +number of times).

Indicates that an AtomPort may be connected to a certain Atom type. A port +MAY support several buffer types.

Note this property only indicates the atom types a port may be directly +connected to, it is not recursive. If a port can be connected to a +collection, use atom:supports to indicate which element types are understood. +If a port supports heterogeneous collections (collections that can contain +several types of elements at once), implementations MUST gracefully handle any +types that are present in the collection, even if those types are not +explicitly supported.

An extension for LV2 plugins which have several execution contexts.

+ +

Contexts allow plugins to run tasks and/or process input/output in +multiple threads. Contexts can be used to add non-realtime functionality +to a plugin while still keeping the audio run() method realtime safe.

+ +

A context is an LV2 feature, so the usual LV2 feature mechanism is used +to determine whether a plugin has a given context, and whether or not it is +mandatory.

+ +

Unless otherwise stated, each context (defined by some URI) adds a new +threading class similar to the Audio class defined by LV2. Each context has a +run callback and a connect_port callback both in the same class (i.e. can't be +called concurrently), but may be called concurrently with functions for other +contexts (excluding the Instantiation class). Context properties such as +ctx:hardRTCapable apply to both functions. +The host MUST only call the correct connect_port function associated with the +context for that port, i.e. it is an error to use the main LV2 connect_port +function on a port with a context other than the main LV2 run function.

+""" . + + +########################## +## Context Base Classes ## +########################## + +ctx:Context a rdfs:Class ; + rdfs:label "LV2 Context" ; + lv2:documentation """ +

A potentially concurrent context (callback) on a plugin.

+ +

Ports are always associated with a context. If a port has no explicit context +property, then its context is ctx:audioContext (the default LV2 run() context).

+ +

A plugin indicates support for a context by supporting an LV2 Feature with +that context's URI. If a plugin optionally supports a context (e.g. +<plugin> lv2:optionalFeature ctx:idleContext .), then +all ports associated with that context MUST be lv2:connectionOptional. Thus, +hosts that do not support contexts will connect such ports to NULL and the +plugin can run with only a standard LV2 run() context.

+ +

Any plugin that supports any context (optionally or mandatorily) MUST adhere +to the following additional threading rules for LV2_Descriptor.connect_port:

+
    +
  • connect_port MUST only be called for a given port from the context +associated with that port
    • +
  • connect_port MAY be called concurrently for ports with different +contexts (but MUST NOT be called concurrently for multiple ports in the +same context)
    • +
+

Note this implies that any shared data access in connect_port may be +accessed concurrently. The plugin is responsible for any synchronisation +or locking necessary to make this possible.

Ports of this type have identical semantics to lv2:AudioPort in terms of +buffer format and connection/input/output logistics.

A +CVPort SHOULD have the same properties a lv2:ControlPort typically +has to describe appropriate control values (e.g. lv2:minimum, lv2:maximum, lv2:default)

Hosts SHOULD take care to prevent data from a CVPort port from being used as +audio except in cases where this is known to be safe.

The LV2 API, on its own, cannot be used to write plugin libraries where data +is dynamically generated at runtime (e.g. API wrappers), since LV2 requires +needed information to be provided in one or more static data (RDF) files. This +API addresses this limitation by extending the LV2 API.

+ +

To detect that a plugin library implements a dynamic manifest generator, +the host checks its static manifest for a description like:

+ +
+<http://example.org/my-dynamic-manifest>
+    a dman:DynManifest ;
+    lv2:binary <mydynmanifest.so> .
+
+ +

To load the data, the host loads the library +(e.g. mydynmanifest.so) as usual and fetches the dynamic Turtle +data from it using this API.

+ +

The host is allowed to request regeneration of the dynamic manifest multiple +times, and the plugin library is expected to provide updated data if/when +possible. All data and references provided via this API before the last +regeneration of the dynamic manifest is to be considered invalid by the host, +including plugin descriptors whose URIs were discovered using this API.

+ +

Accessing Data

+ +

Whenever a host wants to access data using this API, it could:

+ +
    +
  1. Call lv2_dyn_manifest_open().
    2. +
  2. Create a FILE for functions to write data to (e.g. using tmpfile()).
    3. +
  3. Get a list of exposed subject URIs using + lv2_dyn_manifest_get_subjects().
    4. +
  4. Call lv2_dyn_manifest_get_data() for each URI of interest to + get the data related to that URI (which can be written to any FILE).
    5. +
  5. Call lv2_dyn_manifest_close().
    6. +
  6. Parse the content of the FILE(s).
    7. +
  7. Free/delete/unlink the FILE(s).
    8. +
+ +

Each call to the above mentioned dynamic manifest functions MUST write a +complete, valid Turtle document (including all needed prefix definitions) to +the output FILE.

+ +

Each call to lv2_dyn_manifest_open() causes the (re)generation of the +dynamic manifest data, and invalidates all data fetched before the call.

+ +

In case the plugin library uses this same API to access other dynamic +manifests, it MUST implement some mechanism to avoid potentially endless loops +(such as A loads B, B loads A, etc.) and, in case such a loop is detected, the +operation MUST fail. For this purpose, use of a static boolean flag is +suggested.

+ +

Threading Rules

  • "Realtime messages" (status bytes 0xF8 to 0xFF) are allowed, but may + not occur inside other messages like they can in standard MIDI streams.
    • + +
  • All messages are complete valid MIDI messages. This means, for example, + that only the first byte in each event (the status byte) may have the eighth + bit set, that Note On and Note Off events are always 3 bytes long, etc. + Where messages are communicated, the writer is responsible for writing valid + messages, and the reader may assume that all events are valid.

This extension describes a format for presets (i.e. named sets of control +values) for LV2 plugins. The structure of pset:Preset is deliberately very +similar to the description of a plugin and can be thought of as a plugin +overlay. For example:

+ +
+@prefix eg: <http://example.org/> .
+
+eg:mypreset
+    a pset:Preset ;
+    rdfs:label "One louder" ;
+    pset:appliesTo eg:myplugin ;
+    lv2:port [
+        lv2:symbol "volume1" ;
+        pset:value 11
+    ] , [
+        lv2:symbol "volume2" ;
+        pset:value 11.0
+    ] .
+
+ +

Presets may be defined in any bundles, including the plugin's bundle, +separate third party preset bundles, or user-created preset bundles created by +hosts. The manifest.ttl of a bundle containing presets should list the +presets like so:

+ +
+eg:mypreset
+    a              pset:Preset ;
+    pset:appliesTo eg:myplugin ;
+    rdfs:seeAlso   <mypreset.ttl> .
+
+ +

This extension does not define a dynamic mechanism for changing plugin +presets for plugins that require such a facility, but may be extended to do +so.

This extension defines an interface that can be used to create UIs for +plugins. The UIs are code that reside in shared object files in an LV2 +bundle and are referenced in the RDF data using the triples:

+
+@prefix pui: <http://lv2plug.in/ns/ext/pui#> .
+
+<http://example.org/my-ui>
+    a             pui:Gtk2UI ;
+    lv2:appliesTo <http://example.org/my-plugin> ;
+    pui:binary    <my-ui.so> .
+
+

... where http://example.org/my-plugin is the URI of the plugin, +http://example.org/my-ui is the URI of the plugin UI and +my-ui.so is the relative URI to the shared object file. While it +is possible to have the plugin UI and the plugin in the same shared object file +it is probably a good idea to keep them separate so that hosts that don't want +UIs don't have to load the UI code.

+ +

A UI MUST specify its class in the RDF data and the class MUST be a proper +subclass of pui:UI, in this case pui:Gtk2UI. The class defines what type the +UI is, e.g. what graphics toolkit it uses. There are no UI classes defined in +this extension, those are specified separately (and anyone can define their +own).

+ +

It's entirely possible to have multiple UIs for the same plugin, or to have +the UI for a plugin in a different bundle from the actual plugin - this way +people other than the plugin author can write plugin UIs independently without +editing the original plugin bundle. It is also possible to have one UI that +works with several different plugins.

+ +

UIs should also be written in such a way that the host may load several +instances of an UI, or different UIs, and use them with the same plugin +instance.

+ +

Note that the process that loads the shared object file containing the UI +code and the process that loads the shared object file containing the actual +plugin implementation do not have to be the same. There are many valid reasons +for having the plugin and the UI in different processes, or even on different +machines. This means that you can not use singletons and +global variables and expect them to refer to the same objects in the UI and the +actual plugin. The function callback interface defined in the header pui.h is +all you can expect to work.

+""" . + +pui:UI + a rdfs:Class ; + rdfs:subClassOf lv2:Feature ; + rdfs:label "UI" ; + lv2:documentation """ +

The class which represents an LV2 plugin UI. +

+ +

To be used by a host a UI MUST have at least the following properties:

+
    +
  • rdf:type (with object a proper subclass of pui:UI)
    • +
  • doap:name (one without language tag)
    • +
  • lv2:binary (with a shared object file as object)
    • +
  • lv2:appliesTo (with a LV2 plugin as object)
    • +
+ +

The rdf:type of an UI is used by the host to decide whether it supports the +UI and how to handle the LV2_PUI_Widget object that is returned by the UIs +get_widget() function. For example, a type of pui:Gtk2UI might tell the +host that LV2_PUI_Widget is a pointer to an object of a type defined in the +Gtk+ library. No UI types are defined in this extension, that is intentionally +left for other extensions.

+ +

The doap:name property should be at most a few words in length using title +capitalization, e.g. "Flashy Mixer GUI". Use lv2:documentation for more +detailed descriptions.

+ +

UIs may have optional or required features, specified using lv2:optionalFeature +or lv2:requiredFeature. The same rules apply here as for plugins; a host MUST +pass the LV2_Feature objects for all features it supports to the UI's +instantiate() function, a host SHOULD NOT try to instantiate an UI if it +doesn't support all of its required features, and an UI MUST fail to +instantiate if the host doesn't pass all required features to instantiate(). +

+ +

For details about the C API used to load UIs, see the file pui.h. +

+""" . + +pui:PortProtocol + a rdfs:Class ; + rdfs:subClassOf lv2:Feature ; + rdfs:label "Port protocol" ; + lv2:documentation """ +

A PortProtocol defines a certain way of communicating port data between UI +and plugin. PortProtocols can be specified in additional extensions, and +those extensions MUST specify: +

+ +
    +
  1. Which plugin port types the buffer type is valid for
    2. +
  2. When the host should call port_event() in LV2_PUI_Descriptor
    3. +
  3. The format of the data in the buffer passed to port_event()

  6. What data (if any) should be passed in the LV2_Feature data pointer.
    7. +
+ +

For an example, see pui:floatControl or pui:floatPeakRMS. +

The rules (see pui:PortProtocol) for this port protocol are:

    2. +
  2. The host SHOULD call port_event() as soon as possible when the port value + has changed, but the plugin MUST NOT depend on a call for every change or + the timing of the calls. However, the host MUST do the calls in the same + order that the value changes occur in.

+""" . + +pui:floatPeakRMS + a pui:PortProtocol ; + rdfs:label "Peak and RMS for a period of audio data" ; + lv2:documentation """ +

This port protocol defines a way for the host to send continuous peak +and RMS measurements of the audio signal at a certain port to the UI. The +intended use is visualisation, e.g. an animated meter widget that shows +the level of the audio input or output.

+ +

A contiguous sequence of audio samples for which a single peak value +and a single RMS value have been computed is called a measurement +period.

+ +

The rules (see pui:PortProtocol) for this port protocol are:

+
    +
  1. This PortProtocol is valid for ports with the type lv2:AudioPort.
    2. +
  2. The host SHOULD call port_event() at regular intervals. The measurement + periods used for calls to port_event() for the same port SHOULD be + contiguous (i.e. the measurement period for one call should begin right + after the end of the measurement period for the previous call ends) unless + the UI has removed and re-added the port subscription between those calls. + However, UIs MUST NOT depend on either the regularity of the calls or the + contiguity of the measurement periods; hosts may change the call rate + or skip calls for performance or other reasons. Measurement periods for + different calls to port_event() for the same port MUST NOT overlap.
    3. +
  3. The format of the data in the buffer passed to port_event() is a single + LV2_PUI_Peak_RMS_Data object, and the buffer size is + sizeof(LV2_PUI_Peak_RMS_Data).
    4. +
  4. The UI MUST NOT call write_port() with the ID for this port protocol as + the port_protocol parameter.

  3. The data buffer passed to port_event() is an LV2_Event_Buffer, as specified + in the Event extension. The stamp_type MUST be ignored. The frames and + subframes fields of every event in the buffer MUST be ignored. Events with + type 0 (reference counted events) MUST be ignored.

This extension provides a simple mechanism for plugins to save and restore +state across instances, allowing hosts to save and restore a plugin instance's +state at any time. The goal is for an instance's state to be +completely described by port values (as with all LV2 plugins) and a +dictionary.

+ +

The state described by this extension is conceptually a simple +key:value dictionary, where keys are URIDs (URIs mapped to integers) and values +are type-tagged blobs of any type. A single key:value pair is called a +property. To implement state, the plugin provides a state:Interface to +the host. To save or restore, the host calls LV2_State_Interface::save() or +LV2_State_Interface::restore(), passing a callback to be used for handling a +single property. The host is free to implement property storage and retrieval +in any way.

+ +

This state model is simple yet has many benefits:

+
    +
  • URID keys provide both fast performance and RDF compatibility.
    • +
  • Fully extensible, no limitations on keys or value types.
    • +
  • Easy to serialise in many formats (e.g. any RDF syntax, plain + text, JSON, XML, key:value databases, SQL, s-expressions, etc.).
    • +
  • Elegantly described in Turtle, which is useful for describing presets + or default state in LV2 data files (the predicate state:state is provided + for this purpose).
    • +
  • Does not impose any file formats, data structures, or file system + requirements.
    • +
  • Suitable for portable persistent state as well as fast in-memory + snapshots.
    • +
  • Easily stored in a typical map or dictionary data + structure.
    • +
  • Keys may be defined by extensions and used by several plugins, + making state meaningful enabling dynamic state control.
    • +
+ +

Implementations or further extensions which work with plugin state +(including dynamic plugin control) SHOULD work entirely within this model. +That is, do not complicate the state model. All +information required to express an instance's state at any given time can, and +should, be expressed within this model.

+ +

+
+ +

Referring to Existing Files

+ +

Plugins may need to refer to files (e.g. loaded samples) in their state. +This is done by storing the file's path as a property just like any other +value. However, there are some rules which MUST be followed when storing +paths, see state:mapPath for details.

+ +

Creating New Files or Directories

+ +

Implementations are strongly encouraged to avoid the use of files and simply +store all state as properties whenever possible. However, occasionally the +ability to create files is necessary. The feature state:newPath makes this possible, if it is provided by the +host.

+""" . + +state:Interface + a rdfs:Class ; + rdfs:subClassOf lv2:ExtensionData ; + lv2:documentation """ +

A structure (LV2_State_Interface) which contains functions to be called by +the host to save and restore state. In order to support this extension, the +plugin must return a valid LV2_State_Interface from +LV2_Descriptor::extension_data() when it is called with +LV2_STATE_INTERFACE_URI.

+ +

The plugin data file should describe this like so:

+
+@prefix state: <http://lv2plug.in/ns/ext/state#> .
+
+<plugin>
+    a lv2:Plugin ;
+    lv2:extensionData state:Interface .
+
+""" . + +state:State + a rdfs:Class ; + rdfs:label "Plugin Instance State" ; + lv2:documentation """ +

This class is used to express a plugin instance's state in RDF. The +key/value properties of the instance form the predicate/object (respectively) +of triples with a state:State as the subject (see state:state for an example). This may be used wherever it is +useful to express a plugin instance's state in RDF (e.g. for serialisation, +storing in a model, or transmitting over a network). Note that this class is +provided because it may be useful for hosts, plugins, or extensions that work +with instance state, but its use is not required to support the LV2 State +extension.

+""" . + +state:state + a rdf:Property ; + rdfs:range state:State ; + lv2:documentation """ +

Predicate to relate a plugin instance to its State. This may be used +wherever the state of a particular plugin instance needs to be represented. +Note that the domain of this property is unspecified, since LV2 does not define +any RDF class for plugin instance. This predicate may be used wherever it makes +sense to do so, e.g.:

+
+@prefix eg: <http://example.org/> .
+
+<plugininstance>
+    state:state [
+        eg:somekey "some value" ;
+        eg:someotherkey "some other value" ;
+        eg:favourite-number 2
+    ] .
+
+

Note that this property is provided because it may be useful for hosts, +plugins, or extensions that work with instance state, but its use is not +required to support this extension.

+""" . + +state:mapPath + a lv2:Feature ; + rdfs:label "Support for storing paths in files" ; + lv2:documentation """ + +

This feature maps absolute paths to/from abstract paths which are +stored in state. To support this feature a host must pass an LV2_Feature with +URI LV2_STATE_MAP_PATH_URI and data pointed to an LV2_State_Map_Path to the +plugin's LV2_State_Interface methods.

+ +

The plugin MUST map all paths stored in its state (including in any +files in its state). This is necessary to enable host to handle file system +references correctly, e.g. for distribution or archival.

+ +

For example, a plugin may write a path to a state file like so:

+ +
+void write_path(LV2_State_Map_Path* map_path, FILE* myfile, const char* path)
+{
+    char* abstract_path = map_path->abstract_path(map_path->handle, path);
+    fprintf(myfile, "%s", abstract_path);
+    free(abstract_path);
+}
+
+ +

Then, later reload the path like so:

+ +
+char* read_path(LV2_State_Map_Path* map_path, FILE* myfile)
+{
+    /* Obviously this is not production quality code! */
+    char abstract_path[1024];
+    fscanf(myfile, "%s", abstract_path);
+    return map_path->absolute_path(map_path->handle, abstract_path);
+}
+
+""" . + +state:makePath + a lv2:Feature ; + rdfs:label "Support for creating new files and directories" ; + lv2:documentation """ + +

This feature allows plugins to create new files and/or directories. To +support this feature the host passes an LV2_Feature with URI +LV2_STATE_MAKE_PATH_URI and data pointed to an LV2_State_Make_Path to the +plugin. The host may make this feature available only during save by passing +it to LV2_State_Interface::save(), or available any time by passing it to +LV2_Descriptor::instantiate(). If passed to LV2_State_Interface::save(), the +feature MUST NOT be used beyond the scope of that call.

+ +

The plugin is guaranteed a hierarchial namespace unique to that plugin +instance, and may expect the returned path to have the requested path as a +suffix. There is one such namespace, even if the feature is passed to +both LV2_Descriptor::instantiate() and +LV2_State_Interface::save(). Beyond this, the plugin MUST NOT make any +assumptions about the returned paths.

+ +

Like any other paths, the plugin MUST map these paths using state:mapPath before storing them in state. The plugin +MUST NOT assume these paths will be available across a save/restore otherwise, +i.e. only mapped paths saved to state are persistent, any other created paths +are temporary.

+ +

For example, a plugin may create a file in a subdirectory like so:

+ +
+char* save_myfile(LV2_State_Make_Path* make_path)
+{
+    char* path   = make_path->path(make_path->handle, "foo/bar/myfile.txt");
+    FILE* myfile = fopen(path, 'w');
+    fprintf(myfile, "Hello");
+    fclose(myfile);
+    return path;
+}
+
+""" . + +state:Path + a rdfs:Class ; + rdfs:label "Path" ; + lv2:documentation """ +

A path to a file or directory.

+ +

The format of a state:Path is a C string, possibly escaped or otherwise +restricted in a system-specific manner. This URI (LV2_STATE_PATH_URI), mapped +to an integer, MUST be used as the type parameter for any files +passed to the LV2_State_Store_Function; and will likewise be returned by the +corresponding call to the LV2_State_Retrieve_Function.

+ +

When storing and retrieving a path, the plugin MUST NOT assume the same path +will be restored. However, the restored path will refer to a file with +equivalent contents to the original.

Defines ports which contain string data.

+ +

UI issues

+

When using port_event / write_port (and possible other communication +mechanisms), the format parameter should contain the numeric value of URI +LV2_STRING_PORT_URI (mapped with http://lv2plug.in/ns/extensions/ui specified +as map URI).

+ +

It's probably possible to use ports belonging to message context +<http://lv2plug.in/ns/ext/contexts#MessageContext> for transfer. However, +contexts mechanism does not offer any way to notify the message recipient about +which ports have been changed. To remedy that, this extension defines a flag +LV2_STRING_DATA_CHANGED_FLAG that carries that information inside a port value +structure.

+ +

Storage

+

The value of string port are assumed to be "persistent": if a host saves and +restores a state of a plugin (e.g. control port values), the values of input +string ports should also be assumed to belong to that state. This also applies +to message context: if a session is being restored, the host MUST resend the +last value that was sent to the port before session has been saved. In other +words, string port values "stick" to message ports.

+""" . + +sp:StringTransfer a lv2:Feature ; + rdfs:label "String data transfer via LV2_String_Data" . + +sp:StringPort a lv2:Port ; + rdfs:label "String port" ; + lv2:documentation """ +

Indicates that the port data points to a LV2_String_Data structure +as defined in accompanying header file.

+ +

Input Port Semantics

+

If the port does not have a context specified (it runs in the default, +realtime audio processing context), the values in the structure and the actual +string data MUST remain unchanged for the time a run() function of a plugin +is executed. However, if the port belongs to a different context, the same +data MUST remain unchanged only for the time a run() or message_process() +function of a given context is executed.

+ +

Output Port Semantics

+

The plugin may only change the string or length in a run() function (if +the port belongs to default context) or in context-defined counterparts +(if the port belongs to another context). Because of that, using default +context output string ports is contraindicated for longer strings.

This extension defines a simple mechanism for plugins to map URIs to and +from integers, usually for performance reasons (e.g. processing events typed by +URIs in real time). Typically, plugins map URIs to integers for things they +"understand" at instantiation time, and store those values for use in the audio +thread without doing any string comparison. This allows for the extensibility +of RDF but with the performance of integers.

+ +

This extension is intended as an improved and simplified replacement for the +uri-map extension, since the +map context parameter has been found problematic. New implementations +are strongly encouraged to use this extension for URI mapping.

This extension defines an interface that can be used in LV2 plugins and +hosts to create UIs for plugins. The UIs are similar to plugins and reside in +shared object files in an LV2 bundle. UIs are associated with a plugin in RDF +using the triples:

+ +
+@prefix ui: <http://lv2plug.in/ns/extensions/ui#> .
+
+<http://my.plugin>   ui:ui     <http://my.pluginui> .
+<http://my.pluginui> a         ui:GtkUI ;
+                     ui:binary <myui.so> .
+
+ +

where <http://my.plugin> is the URI of the plugin, +<http://my.pluginui> is the URI of the plugin UI and <myui.so> is +the relative URI to the shared object file.

+ +

While it is possible to have the plugin UI and the plugin in the same shared +object file it is probably a good idea to keep them separate so that hosts that +don't want UIs don't have to load the UI code. A UI MUST specify its class in +the RDF data (ui:GtkUI in the above example). The class defines what type the +UI is, e.g. what graphics toolkit it uses. Any type of UI class can be defined +separately from this extension.

+ +

It is possible to have multiple UIs for the same plugin, or to have the UI +for a plugin in a different bundle from the actual plugin - this way people +other than the plugin author can write plugin UIs independently without editing +the original plugin bundle.

+ +

Note that the process that loads the shared object file containing the UI +code and the process that loads the shared object file containing the actual +plugin implementation are not necessarily the same process (and not even +necessarily on the same machine). This means that plugin and UI code can +not use singletons and global variables and expect them to +refer to the same objects in the UI and the actual plugin. The function +callback interface defined in this header is the only method of communication +between UIs and plugin instances (extensions may define more, though this is +discouraged unless absolutely necessary since the significant benefits of +network transparency and serialisability are lost).

+ +

Since the LV2 specification itself allows for extensions that may add new +functionality that could be useful to control with a UI, this extension allows +for meta-extensions that can extend the interface between the UI and the +host. These extensions mirror the extensions used for plugins - there are +required and optional "features" that you declare in the RDF data for the +UI:

+ +
+<http://my.pluginui> lv2:requiredFeature <http://my.feature> .
+<http://my.pluginui> lv2:optionalFeature <http://my.feature> .
+
+ +

The rules for a UI with a required or optional feature are identical to +those of lv2:Plugin instances: if a UI declares a feature as required, the host +is NOT allowed to load it unless it supports that feature; and if it does +support a feature, it MUST pass an appropriate LV2_Feature struct to the UI's +instantiate() method. These features may be used to specify how to pass +specific types of data between the UI and the plugin port buffers (see +LV2UI_Write_Function for details).

+ +

UIs written to this specification do not need to be threadsafe - the +functions defined below may only be called in the same thread the UI main loop +is running in.

+ +

Note that this UI extension is NOT a lv2:Feature. There is no way for a +plugin to know whether the host that loads it supports UIs or not, and the +plugin must always work without the UI (although it may be rather useless +unless it has been configured using the UI in a previous session). From the +plugin perspective, control from a UI is the same as control from anywhere else +(e.g. the host, the user): via ports.

+ +

A UI does not have to be a graphical widget, it could just as well be a +server listening for OSC input or an interface to some sort of hardware device, +depending on the RDF class of the UI.

This extension defines a number of units for use in audio processing.

+ +

For example, to say that a gain port's value is in decibels (units:db)

+
+@prefix units: <http://lv2plug.in/ns/extensions/units#> .
+@prefix eg:    <http://example.org/> .
+
+eg:plugin lv2:port [
+    a            lv2:ControlRateInputPort ;
+    lv2:datatype lv2:Float ;
+    lv2:index    0 ;
+    lv2:symbol   "gain" ;
+    lv2:name     "gain" ;
+    units:unit   units:db
+] .
+
+ +

Using the same form, plugins may also specify one-off units inline, to give +better display hints to hosts:

+
+eg:plugin lv2:port [
+    a            lv2:ControlRateInputPort ;
+    lv2:datatype lv2:Float ;
+    lv2:index    0 ;

+        units:symbol "fr" ;
+        units:render "%f f"
+    ]
+] .
+
+ +

It is also possible to define conversions between various units, which makes +it possible for hosts to automatically and generically convert from a given +unit to a desired unit. The units defined in this extension include conversion +definitions where it makes sense to do so.

The standard language tagging facility of RDF can be +used to provide multi-lingual documentation.

XHTML Basic is a W3C Recommendation which defines a basic subset of XHTML +intended to be reasonable to implement with limited resources (e.g. on embedded +devices). See XHTML Basic, Section 3 for a list of legal tags.

+""" . + + + a owl:Ontology ; + owl:imports ; + lv2:documentation """ +

LV2 is an interface for writing audio processors, or plugins, in +C/C++ which can be dynamically loaded into many applications, or hosts. +This core specification is simple and minimal, but is designed so that +extensions can be defined to add more advanced features, making it +possibly to implement nearly any feature imaginable.

+ +

LV2 maintains a strong distinction between code and data. +Plugin code is in a shared library, while data is in a companion data file +written in Turtle. +Code, data, and any other resources (e.g. waveforms) are shipped together in a +bundle directory. The code contains only the executable portions of the +plugin which inherently must be written in code. All other data is +provided in the data file(s). This makes plugin data flexible and extensible, +and allows the host to do everything but run the plugin without loading or +executing any code. Among other advantages, this makes hosts more robust +(broken plugins can't crash a host during discovery) and allows generic tools +and non-C programs to work with LV2 data. LV2 itself and extensions are +distributed in a similar way.

+ +

An LV2 plugin library is suitable for dynamic loading (e.g. via +dlopen()) and provides one or more plugin descriptors via the +lv2_descriptor() function. These can be instantiated to create +plugin instances, which can be run directly on data or connected +together to perform advanced signal processing tasks.

+ +

Plugins communicate via ports, which can transmit any type of data. +Data is processed by first connecting each port to a buffer, then +repeatedly calling a plugin's run() method to process blocks of +data.

+ +

This core specification defines two types of port, equivalent to those in LADSPA: lv2:ControlPort and lv2:AudioPort. +Audio ports contain arrays with one float element per sample, +allowing a block of audio to be processed in a single call to +run(). Control ports contain single float values, +which are fixed and valid for the duration of the call to run(). +Thus the control rate is determined by the block size, which is +controlled by the host (and not necessarily constant).

+ +

Threading Rules

+ +

To faciliate use in multi-threaded programs, LV2 functions are partitioned +into several threading classes:

+ + + + + + + + + + + + + +
Discovery ClassInstantiation ClassAudio Class
lv2_descriptor()LV2_Descriptor::instantiate()LV2_Descriptor::run()
LV2_Descriptor::extension_data()LV2_Descriptor::cleanup()LV2_Descriptor::connect_port()
LV2_Descriptor::activate()
LV2_Descriptor::deactivate()
+ +

The rules that hosts MUST follow are:

+
    +
  • When any function is running for a plugin instance, +no other function in the same class may run for that instance.
    • +
  • When a Discovery function is running, +no other functions in the same shared object file may run.
    • +
  • When an Instantiation function is running for a plugin instance, +no other functions for that instance may run.
    • +
+ +

Any simultaneous calls that are not explicitly forbidden by these rules are +allowed. For example, a host may call run() for two different +plugin instances simultaneously.

+ +

Plugin functions in any class MUST NOT manipulate any state which might +affect other plugin or host code, e.g. by using non-reentrant global +functions.

+ +

Extensions to this specification which add new functions MUST declare in +which of these classes the functions belong, define new classes for them, or +otherwise precisely describe their threading rules.

The minor version of an LV2 Resource. This property is used (along with +lv2:microVersion) by hosts to distinguish different versions of a compatible +resource, e.g. to load only the bundle with the most recent version.

+ +

The version of an LV2 resource is composed of two fields: minor version, +and micro version. These have the usual semantics:

+ +
    +
  • The minor version MUST be incremented when backwards (but not +forwards) compatible additions are made, e.g. the addition of a port to a +plugin.
    • + +
  • The micro version is incremented for changes which do not affect +compatibility at all, e.g. bug fixes or documentation updates.
    • +
+ +

Note there is deliberately no concept of a major version: all versions of an +LV2 resource with a given URI are by definition backwards compatible. More +precisely: replacing a resource with a newer version of that resource MUST NOT +break anything. If a change is made which breaks this rule, the URI +of the resource MUST be changed. In contexts where a full (e.g. SemVer conformant) version number is required, the +major version of all released LV2 resources is 1.

+ +

Plugins and extensions MUST adhere to the following rules:

+
    +
  • All versions of a plugin with a given URI MUST have the same set of +mandatory (i.e. not lv2:connectionOptional) ports with respect to lv2:symbol +and rdf:type. In other words, every port on a specific version of a plugin has +a lv2:symbol and a set of rdf:types; all future versions of that plugin are +guaranteed to have a port with the same lv2:symbol and at least those +rdf:types. New types may be added only if doing so does not break +compatibility, i.e. if old hosts will continue to work correctly with the new +plugin.
    • + +
  • New ports MAY be added without changing the plugin URI if and only if they +are lv2:connectionOptional and the minor version is incremented.
    • + +
  • The minor version MUST be incremented if the index of any port (identified +by its symbol) is changed.
    • + +
  • All versions of an extension MUST be compatible in the sense that an +implementation of the new version can interoperate with an implementation of +any previous version.
    • +
+ +

(Note these rules are not necessarily exhaustive)

+ +

Anything that depends on a specific version of a plugin (e.g. a +serialisation that references ports by index) MUST refer to the plugin by both +URI and version. However, implementations should be tolerant and extensions +should be designed such that there is no need to do this (e.g. indices should +only be meaningful for a particular plugin instance at run-time).

+ +

When hosts discover several installed versions of a resource, they SHOULD +warn the user and load only the most recent version.

+ +

An odd minor or micro version indicates that the resource is a +possibly unstable development version. Hosts and tools SHOULD clearly indicate +this wherever appropriate. Several versions of a resource with an odd version +may exist; i.e. it is acceptable to work on a development version of a resource +(e.g. in source control) without worrying about version numbers as long as +either the minor or micro version is odd.

+ +

This property describes half of a resource version. See also lv2:minorVersion, the +property which describes the other half.

+""" . + +lv2:microVersion a rdf:Property , owl:DatatypeProperty ; + rdfs:domain lv2:Resource ; + rdfs:range xsd:nonNegativeInteger ; + rdfs:label "micro version" ; + lv2:documentation """ +

The micro component of a Resource's version.

+ +

Releases of plugins and extensions MUST be explicitly versioned. Correct +version numbers MUST always be maintained for any versioned resource that is +published. For example, after a release, if a change is made in the development +version in source control, the micro version MUST be incremented (to an odd +number) to distinguish this modified version from the previous release.

+ +

This property describes half of a resource version. For detailed +documentation on LV2 resource versioning, see lv2:minorVersion.

The lv2:binary of an lv2:Plugin is the +shared object containing the lv2_descriptor() function which can +be used to access the descriptor for that plugin. This property may be used +similarly by extensions to relate other resources to their implementations.

Specifies that a resource is related to a plugin. This is primarily intended +for discovery purposes: bundles that describe resources that work with +particular plugins (e.g. presets or user interfaces) SHOULD use this predicate +in manifest.ttl to relate the resource to the applicable +plugin(s), e.g.:

+""" . + +lv2:hardRTCapable a lv2:Feature ; + rdfs:label "Hard realtime capable" ; + lv2:documentation """ +

Indicates that the plugin is capable of running not only in a conventional +host but also in a hard real-time environment. To qualify for this the +plugin MUST satisfy all of the following:

+
    +
  1. The plugin MUST NOT use malloc(), free() or other heap memory management + functions within its Audio class functions.
    2. + +
  2. The plugin MUST NOT attempt to make use of any library functions in its + Audio class functions, unless those functions themselves adhere to these + rules (i.e. are hard realtime safe). The plugin MAY assume the standard C + and C math library functions are safe.
    3. + +
  3. The plugin will not access files, devices, pipes, sockets, IPC or any other + mechanism that might result in process or thread blocking within its Audio + class functions.
    4. + +
  4. The plugin will take an amount of time to execute a run() call + approximately of form A + B * sample_count where A + and B depend on the machine and host in use. This amount of + time MUST NOT depend on input signals or plugin state.
    5. +
+

Note these rules apply to the connect_port() function as well as run().
