+ lv2:documentation """
+<p>This extension defines a generic format for a typed piece of data, called an
+lv2:Atom (e.g. integers, strings, buffers, data structures,
+etc). Atoms allow LV2 plugins and hosts to communicate, process, serialise,
+and store values of any type via a generic mechanism (e.g. LV2 ports, events,
+disk, shared memory, network). Atoms are, with one exception, Plain
+Old Data (POD) and may be safely copied (e.g. with a simple call to
+<code>memcpy</code>).</p>
+
+<p>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.</p>
+
+<p>An Atom can be trivially constructed in-place from an
+<a href="http://lv2plug.in/ns/ext/event#Event">Event</a> as defined by the
+<a href="http://lv2plug.in/ns/ext/event">LV2 Event</a> extension. In other
+words, an Event is simply an Atom with a time stamp header. Atoms SHOULD
+be used anywhere a "value" needs to be stored or communicated, to allow
+implementations to be polymorphic and extensible.</p>
+
+<p>Atoms (the start of the LV2_Atom header) MUST be 32-bit aligned.</p>
+
+<p>Atoms can be communicated in many ways. Since an Atom is the payload of an
+Event, an <a href="http://lv2plug.in/ns/ext/event#EventPort">EventPort</a> can
+be used for communicating Atoms in realtime with sub-sample time stamp
+accuracy. This extension also defines two port types for connecting directly
+to a single Atom: atom:ValuePort and atom:MessagePort, which both have the same
+buffer format but different semantics (with respect to how the run() callback
+interprets the Atom).</p>
+
+<p>Implementing this extension requires a facility for mapping URIs to
+integers, such as the <a href="http://lv2plug.in/ns/ext/urid">LV2 URID</a>
+extension.</p>

+<p>An extension for LV2 plugins which have several execution contexts.</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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.</p>

+ lv2:documentation """
+<p>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.</p>
+
+<p>To detect that a plugin library implements a dynamic manifest generator,
+the host checks its static manifest for a description like:</p>
+
+<pre class="turtle-code">
+&lt;http://example.org/my-dynamic-manifest&gt;
+ a dman:DynManifest ;
+ lv2:binary &lt;mydynmanifest.so&gt; .
+</pre>
+
+<p>To load the data, the host loads the library
+(e.g. <code>mydynmanifest.so</code>) as usual and fetches the dynamic Turtle
+data from it using this API.</p>
+
+<p>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.</p>
+
+<h3>Accessing Data</h3>
+
+<p>Whenever a host wants to access data using this API, it could:</p>
+
+<ol>
+<li>Call lv2_dyn_manifest_open().</li>
+<li>Create a FILE for functions to write data to (e.g. using tmpfile()).</li>
+<li>Get a <q>list</q> of exposed subject URIs using
+ lv2_dyn_manifest_get_subjects().</li>
+<li>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).</li>
+<li>Call lv2_dyn_manifest_close().</li>
+<li>Parse the content of the FILE(s).</li>
+<li>Free/delete/unlink the FILE(s).</li>
+</ol>
+
+<p>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.</p>
+
+<p>Each call to lv2_dyn_manifest_open() causes the (re)generation of the
+dynamic manifest data, and invalidates all data fetched before the call.</p>
+
+<p>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.</p>
+
+<h3>Threading Rules</h3>
+
+<p>All of the functions defined by this specification belong to the Discovery
+class.</p>

+<p>This extension provides a mechanism for plugins to portably refer to files
+in persistent plugin state (using the <a
+href="http://lv2plug.in/ns/ext/persist">LV2 Persist</a> extension), and create
+instance-local files in host-defined locations (e.g. for recording).</p>
+
+<p>The motivating idea behind this extension is that all details of file
+management MUST be handled by the host since different hosts may have very
+different requirements. Plugins MUST NOT make any assumption about file system
+locations beyond what is explicitly guaranteed by this extension.</p>
+
+<p>This extension defines two features: files:newFileSupport allows plugins to
+create new files within an instance-specific namespace at any time (except in
+realtime contexts); while files:pathSupport allows plugins to refer to file
+paths in plugin state in a way transparent to the host.</p>
+
+<p>To create a new file, the plugin MUST request a path from the host using
+LV2_Files_New_File_Support::new_file_path(). Thus, the host may choose an
+appropriate location for the file (e.g. a writable path on the appropriate disk
+volume or a path within a session directory) using information not available to
+the plugin.</p>
+
+<p>To store a path in persistent state, the plugin MUST map it to an
+<q>abstract path</q> using LV2_Files_Path_Support::abstract_path(). To use a
+path loaded from persistent state, the plugin MUST map the (abstract) path to
+an absolute path using LV2_Files_Path_Support::absolute_path(). Thus, the host
+can manage all paths used in a session and support exporting sessions to a
+portable self-contained format for archival or distribution.</p> """ .

+LV2_FILES_PATH_SUPPORT_URI and LV2_Feature::data pointed to an instance of

+
+<p>Abstract paths reside in a namespace specific to a plugin instance.

+<p>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:</p>
+<pre class="turtle-code">
+@prefix pui: &lt;http://lv2plug.in/ns/ext/pui#&gt; .
+&lt;http://example.org/my-ui&gt; a pui:Gtk2UI ;
+ lv2:appliesTo &lt;http://example.org/my-plugin&gt; ;
+ pui:binary &lt;my-ui.so&gt; .
+</pre>
+<p>... where <code>http://example.org/my-plugin</code> is the URI of the plugin,
+<code>http://example.org/my-ui</code> is the URI of the plugin UI and
+<code>my-ui.so</code> 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.</p>
+
+<p>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).</p>
+
+<p>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.</p>
+
+<p>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.</p>
+
+<p>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 <strong>not</strong> 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.</p>

+<p>The class which represents an LV2 plugin UI.

+<li>lv2:appliesTo (with a LV2 plugin as object)</li>
+</ul>
+
+<p>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.</p>

+capitalization, e.g. "Flashy Mixer GUI". Use lv2:documentation for more
+detailed descriptions.</p>

+<p>This extension provides a mechanism for plugins to save and restore state
+across instances, allowing hosts to save, restore, clone, or take a snapshot of
+a plugin instance's state at any point in time. The intention is for a plugin
+instance's state to be <em>completely</em> described by port values (as with all
+LV2 plugins) and a simple dictionary.</p>
+
+<p>The <q>state</q> described by this extension is conceptually a single
+key/value dictionary, where keys are URIDs and values are type-tagged blobs of
+any type. The plugin provides an LV2_State_Interface for working with this
+state. 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 key/value pair. The host is free to implement saving and restoring in
+any way; the actual mechanism is completely abstract from the plugin's
+perspective.</p>
+
+<p>Because state is a simple dictionary, hosts and plugins can work with it
+easily from many languages and protocols. Keys are URIDs for performance
+reasons as well as RDF compatibility, which makes it simple to serialise state
+in many formats (e.g. any RDF syntax, JSON, XML, key/value databases such as
+BDB, etc.). In particular, state can be elegantly described in a plugin's
+Turtle description, which is useful for e.g. presets or default state.
+Specific keys may be described in Turtle on the fly or in extensions,
+allowing plugins to use common well-defined keys.</p>
+
+<p>This extension defines a conceptual model of state and a mechanism for
+saving and restoring it, but no interface for manipulating it dynamically.
+While no such mechanism is defined here, dynamic control of plugins SHOULD be
+achieved by generic manipulations of the same conceptual state dictionary used
+by this extension (e.g. <code>plugin->set(key, value)</code>). Accordingly,
+plugins SHOULD use meaningful and well-defined keys wherever possible.</p>
+
+<p>In pseudo code, a typical use case in a plugin is:</p>
+<pre class="c-code">
+#define NS_EG "http://example.org/"
+#define NS_ATOM "http://lv2plug.in/ns/ext/atom#"
+
+LV2_Handle my_instantiate(...)

+<h4>UI issues</h4>

+LV2_STRING_PORT_URI (mapped with http://lv2plug.in/ns/extensions/ui specified
+as map URI).</p>

+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.</p>
+
+<h4>Storage</h4>
+<p>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

+<p>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.</p>
+
+<p>This extension is intended as an improved and simpler replacement for the <a
+href="http://lv2plug.in/ns/ext/uri-map">uri-map</a> extension, since the
+<q>map</q> context parameter has been found problematic.</p>
