Abstract
A Common Annotation Framework includes, in an embodiment, an annotation having a context anchor that identifies a resource and a position in the resource that the annotation pertains to, and a content anchor that identifies data that is annotating the resource. The annotation can also be extended with client application-defined data and/or functionality, and the framework can be extended with one or more of application-defined objects, methods, and annotation stores.
