Definition[edit]
A content relation in eSciDoc is a resource that relates two content objects. A content relation can relate:
- Content item with another content item
- Content container with another content container
- Content item with a content container
Note: content relations are binary and bi-directional relations i.e.
- a content relation can be established only by two content objects
- a content relation a->b also assumes a content relation b->a
- directions a->b and b->a may have different labels (e.g. isRevisionOf, hasRevisions) that are expressed with a specific relation ontology
A content relation has the following properties:
- Relation type: defines the meaning of how two content objects (items, container) are related. This meaning is expressed with an ontology (such as Fedora relation ontology, eSciDoc relation ontology) for both directions of the relation
