+
+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:
+
+    :::turtle
+    <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
+
+To access data using this API, the host must:
+
+  1. Call lv2_dyn_manifest_open().
+
+  2. Create a `FILE` for functions to write data to (for example with `tmpfile()`).
+
+  3. Get a list of exposed subject URIs using lv2_dyn_manifest_get_subjects().
+
+  4. Call lv2_dyn_manifest_get_data() for each URI of interest to write the
+  related data to the file.
+
+  5. Call lv2_dyn_manifest_close().
+
+  6. Parse the content of the file(s).
+
+  7. Remove the file(s).
+
+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
+
+All of the functions defined by this specification belong to the Discovery
+class.
