Note

Only one of the attributes active and mutual may be supplied; the attribute passive may be supplied only if the attribute active is supplied. Not all of these constraints can be enforced in all schema languages.

Example
<relation type="social" name="supervisor"
 active="#p1" passive="#p2 #p3 #p4"/>

This indicates that the person with identifier p1 is supervisor of persons p2, p3, and p4.

Example
<relation type="personal" name="friends"
 mutual="#p2 #p3 #p4"/>

This indicates that p2, p3, and p4 are all friends.

Example
<relation type="CRM"
 name="P89_falls_within"
 active="http://id.clarosnet.org/places/metamorphoses/place/italy-orvieto"
 passive="http://id.clarosnet.org/places/metamorphoses/country/IT"/>

This indicates that there is a relation, defined by CIDOC CRM, between two resources identified by URLs.

Example
<relation resp="http://viaf.org/viaf/44335536/"
 ref="http://purl.org/saws/ontology#isVariantOf"
 active="http://www.ancientwisdoms.ac.uk/cts/urn:cts:greekLit:tlg3017.Syno298.sawsGrc01:divedition.divsection1.o14.a107"
 passive="http://data.perseus.org/citations/urn:cts:greekLit:tlg0031.tlg002.perseus-grc1:9.35"/>

This example records a relationship, defined by the SAWS ontology, between a passage of text identified by a CTS URN, and a variant passage of text in the Perseus Digital Library, and assigns the identification of the relationship to a particular editor (all using resolvable URIs).
