We are pleased to announce the publication of the Open Annotation Specification (Community Draft 2). This work is the product of the W3C Open Annotation Community Group jointly founded by the Annotation Ontology initiative and the Open Annotation Collaboration. In 2013, with the support of the Open Annotation Collaboration and the Andrew W. Mellon Foundation, the W3C OA Community Group hosted three public rollouts of this specification: U.S. West Coast, U.S. East Coast, and in the U.K. These rollouts concluded the work of the Open Annotation Collaboration. This work is now being carried on by the W3C Open Annotation Community Group. This Web site is maintained for historical purposes.
