Our Graph Data Model (GDM) makes use of RDF concepts on top of the (more powerful) property graph model, which allows relationships to have not only a type, but an arbitrary number of properties. Comparison by example:

<table">

Feature RDF GDM resource (URI resource, bnode) Node Node attribute rdf:Property instance (predicate) Relationship Type statement (subject, predicate, object) Triple Relationship (= predicate) (incl. start node (= subject) + end node (= object)) resource identifier URI **uri** property of a Node + has a node label **RESOURCE** (or **TYPE_RESOURCE**) value Literal **value** property of a Node + has a node label **LITERAL** n-ary relationships/ qualified attributes of a statement n.a. / reification property of a Relationship, e.g. **order**, **index**, **data_model** order (in a list, i.e., statements that have the same subject and predicate) n.a. / reification **order** property of a Relationship index (absolut position of a statement in a container of statements that belong to a certain Resource (cf. CBD etc.)) n.a. / reification **index** property of a Relationship provenance Named Graph **data_model** property of a Relationship
