Participation
Intent
This pattern can be used to model simple participation relations, involving just one object and one event.
The pattern is specialized from the http://www.loa-cnr.it/ontologies/DUL.owl.
If you need to talk about participation with more objects or events, or with time indexing, use the N-ary participation pattern.
Examples

Co-participation
Intent Code
The pattern is useful in order to talk e.g. of linguistic 'thematic roles' and most verb-based concepts, such as 'meets', 'funds', 'loves', etc.
The pattern is extracted from http://www.loa-cnr.it/ontologies/DUL.owl.
If time indexing is needed, you can use or specialize the N-ary participation pattern.
Examples
John loves Mary.

Collection Entity
Intent
This pattern can be used to model collections as individuals, and membership as an owl:ObjectProperty.
The pattern is useful in order to talk directly about collections.
The pattern is extracted from http://www.loa-cnr.it/ontologies/DUL.owl.
If time indexing is needed, you can use or specialize the "classification" pattern.
Examples
Qatar is one of the Arab League states. A main goal of the Arab League is to draw closer the relations between member States.

The pattern is extracted from http://www.loa-cnr.it/ontologies/DUL.owl.
