The aim of the 3D Semantic Annotation (3DSA) system is to deliver a Web-based semantic tagging and annotation service for 3D cultural heritage objects - that enables users to attach semantic tags/annotations to points, surface regions and volumetric segments on 3D digital objects. Specific objectives of the 3DSA system are: support for interactively defined, complex 3D segments; interoperability of the resulting tags/annotations; and fast, efficient capture, retrieval and rendering of annotations on complex 3D fragments. With these objectives in mind, the 3DSA system is based on the Open Annotations Collaboration (OAC) model, which has been extended using X3D fragment identifiers. This paper describes our implementation of the X3D extensions to the OAC data model and demonstrates how this approach significantly improves the speed of capturing, retrieving, downloading and rendering annotations on volumetric segments. The context for this work is the capture of community-generated tags and annotations for cultural heritage artifacts from the University of Queensland Antiquities Museum.
