RGML Specification

The RDF Graph Modeling Language (RGML) is a W3C RDF vocabulary to describe graph structures, including semantic information associated with a graph. Viewing general graphs as Web resources, RGML defines graph, node, and edge as RDF classes and attributes of graphs (such as label and weight) as RDF properties. Some of these RDF properties establish relationships between graph, node, and edge instances. RDF Statements about graph elements involve subjects, predicates and objects. Subjects and predicates are RDF Resources, while objects are either RDF Resources or RDF Literals. RGML uses the XML Schema datatypes for RDF Literals. RGML can be easily combined with other RDF vocabularies, for example, to add Dublin Core properties. RGML is very useful for describing webgraphs (the structure of a web site), web collections, and sitemaps.
