Open Annotation Collaboration
http://openannotation.org/

Annotating is a pervasive element of scholarly practice for both the humanist and the scientist. Over time annotations have scholarly value in their own right. The importance of annotating as a scholarly practice coupled with the real-world limitations of existing practices and tools supporting annotation of digital content has had a retarding effect on the growth of digital scholarship and the level of digital resource use by scholars. The overarching goals of the Open Annotation Collaboration (OAC) are to facilitate to 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 the utility of this environment, and to see widespread adoption of this environment.
