Schema for characterizing relationships with roles
This schema provides the most basic classes and slots to qualify
relationships between two things. The connection to the
thing-schema is the qualified_relations
slot, which can be used to qualify relations between things via any number
of Relationship declarations.
Each Relationship links one object (Thing) to a subject (Thing) and
associates one or more roles (Role) with this relationship via the
roles slot.
A Role is itself a Thing, and can be annotated with (inline)
attributes as needed. However, typically it should be sufficient
to reference a role by a URI.
This schema also incorporates the schemas
The schema definition is available as
