Open Annotation Collaboration (Phases I, II and III)


This 3-phase project seeks to facilitate the emergence of a Web and Resource-centric interoperable annotation environment that allows leveraging annotations across the boundaries of annotation clients, annotation servers, and content collections; to demonstrate through implementations an interoperable annotation environment enabled by the interoperability specifications in settings characterized by a variety of annotation client/server environments, content collections, and scholarly use cases; and to seed widespread adoption by deploying robust, production-quality applications conformant with the interoperable annotation environment in ubiquitous and specialized services, tools, and content used by scholars.

The current phase, Phase III, will cement, preserve and further establish the foundation created by the outcomes of OAC Phases I and II. In order to facilitate broad adoption and sustainability of the Open Annotation data model the OAC Phase III team is:
  •  systematically developing the OA community and engaging digital annotation stakeholders; and
  • providing essential community infrastructure elements.
