+      	<p>The Qualified involvement classes allow for the representation of qualifying information on the core provenance relations used, wasGeneratedBy, generation, and hadParticipant which are defined as OWL object properties in PROV-O.</p>
+      	<p>The OWL classes Usage, Generation, Control, and Participation are specializations of the class QualifiedInvolvement.  For each QualifiedInvolvement there must be some entity referenced via the property hadQualifiedEntity, for Participation and Control this entity is inferred to have type Agent.</p>
+      	<p>Qualified Involvement exists so qualifiers may be represented on core provenance relations between entities and activities. An example qualifier would be role information for an entity's involvement in the activity.  Role information always describes the entities function within the context of the entities association with the activity, which is why role is expressed on the QualifiedInvolvement.  Other qualifying information could include, time of involvement, location of entity in involvement, authority of agent in control, subset of document used in a usage, etc.  Only a few universal qualifiers will be defined in PRO-O, it is expected that users will define domain-specific qualifiers based on their unique requirements.</p>
