+<p>This extension defines a generic container for data, called an <q>Atom</q>,
+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 <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>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 <a
+href="http://lv2plug.in/ns/ext/event">LV2 event</a> extension.</p>
+
+<p>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 <code>struct</code> type).  New binary formats are an
+implementation burden which harms interoperabilty, and should only be defined
+where absolutely necessary.</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>

+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 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

+	lv2:documentation """
+<p>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
+<em>completely</em> described by port values (as with all LV2 plugins) and a
+dictionary.</p>
+
+<p>The <q>state</q> 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
+<q>property</q>.  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.</p>
+
+<p>This state model is simple yet has many benefits:</p>
+<ul>
+  <li>URID keys provide both fast performance and RDF compatibility.</li>
+  <li>Fully extensible, no limitations on keys or value types.</li>
+  <li>Easy to serialise in many formats (e.g. any RDF syntax, plain
+  text, JSON, XML, key:value databases, SQL, s-expressions, etc.).</li>
+  <li>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).</li>
+  <li>Does not impose any file formats, data structures, or file system
+  requirements.</li>
+  <li>Suitable for portable persistent state as well as fast in-memory
+  snapshots.</li>
+  <li>Easily stored in a typical <q>map</q> or <q>dictionary</q> data
+  structure.</li>
+  <li>Keys may be defined by extensions and used by several plugins,
+  making state meaningful enabling dynamic state control.</li>
+</ul>
+
+<p>Implementations or further extensions which work with plugin state
+(including dynamic plugin control) SHOULD work entirely within this model.
+That is, <strong>do not complicate the state model</strong>.  <em>All</em>
+information required to express an instance's state at any given time can, and
+should, be expressed within this model.</p>

+<h3>Referring to Existing Files</h3>
+
+<p>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 <a href="#mapPath">state:mapPath</a> for details.</p>
+
+<h3>Creating New Files or Directories</h3>
+
+<p>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 <a
+href="#newPath">state:newPath</a> makes this possible, if it is provided by the
+host.</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
+last value that was sent to the port before session has been saved. In other
+words, string port values "stick" to message ports.</p>
