YUMA is an open-source annotation framework and set of tools developed for annotating multimedia objects on the web, including historic maps. It allows for cooperative annotation and research. The demo annotates a historic map from the Library of Congress with places, people and descriptions. YUMA implements the Open Annotation data model to link annotations to targets on maps and other metadata. Issues being addressed include tiled map annotations and content negotiation.

6. YUMA and OAC
• YUMA implements the following models:
• LEMO (default)
• OAC Alpha 3 (beta)
• OAC should become the default model
