+	lv2:documentation """
+
+This is a vocabulary for LV2 plugin presets, that is, named sets of control
+values and possibly other state.  The structure of a pset:Preset is
+deliberately identical to that of an lv2:Plugin, and can be thought of as a
+plugin template or overlay.
+
+Presets may be defined in any bundle, including the plugin's bundle, separate
+third party preset bundles, or user preset bundles saved by hosts.  Since
+preset data tends to be large, it is recommended that plugins describe presets
+in a separate file(s) to avoid slowing down hosts.  The `manifest.ttl` of a
+bundle containing presets should list them like so:
+
+    :::turtle
+    eg:mypreset
+        a             pset:Preset ;
+        lv2:appliesTo eg:myplugin ;
+        rdfs:seeAlso  <mypreset.ttl> .
+
+"""^^lv2:Markdown .
+
+pset:Preset
+	lv2:documentation """
+
+The structure of a Preset deliberately mirrors that of a plugin, so existing
+predicates can be used to describe any data associated with the preset.  For
+example:
+
+    :::turtle
+    @prefix eg: <http://example.org/> .
+
+    eg:mypreset
+        a pset:Preset ;
+        rdfs:label "One louder" ;
+        lv2:appliesTo eg:myplugin ;
+        lv2:port [
+            lv2:symbol "volume1" ;
+            pset:value 11.0
+        ] , [
+            lv2:symbol "volume2" ;
+            pset:value 11.0
+        ] .
+
+A Preset SHOULD have at least one lv2:appliesTo property.  Each Port on a
+Preset MUST have at least a lv2:symbol property and a pset:value property.
+
+Hosts SHOULD save user presets to a bundle in the user-local LV2 directory (for
+example `~/.lv2`) with a name like `<Plugin_Name>_<Preset_Name>.preset.lv2`
+(for example `LV2_Amp_At_Eleven.preset.lv2`), where names are transformed to be
+valid LV2 symbols for maximum compatibility.
+
+"""^^lv2:Markdown .
+
+pset:value
+	lv2:documentation """
+
+This property is used in a similar way to lv2:default.
+
+"""^^lv2:Markdown .
+
+pset:preset
+	lv2:documentation """
+
+Specifies the preset currently applied to a plugin instance.  This property may
+be useful for saving state, or notifying a plugin instance at run-time about a
+preset change.
