Annotation Ontology

The Annotation Ontology specification is currently used as input for the activities of the http://www.w3.org/community/openannotation/'>W3C Open Annotation Community Group that works towards a common, RDF-based, specification for annotating digital resources. The Group effort starts by working towards a reconciliation of two proposals that have emerged over the past two years: the http://code.google.com/p/annotation-ontology/'>Annotation Ontology and the http://www.openannotation.org/spec/beta/'>Open Annotation Model.
