These exercises are usually a one-off as the technology and resources required are cost intensive. However, there is a recent impetus on the creation of 3D collections to document heritage artefacts which are semantically enriched by using annotations. A requirement of these solutions is the ability to support several representations of a heritage artefact recorded through time. This paper will propose an infrastructure to systematically enrich 3D shapes in a collection by using propagated annotations. In addition, it will describe the mechanisms for annotating, propagating and structuring the annotations using the CIDOC-CRM ontology. The results of this research have the potential to support heritage organisations in making their semantically rich 3D content available to a wider audience of professionals.E.2 [Data]Data Storage and RepresentationsLinked representations H.3.1 [Information Systems]Information Storage and RetrievalContent Analysis and IndexingAbstracting methods H.3.7 [Information Systems]Information Storage and RetrievalDigital Libraries[ Collection]I.3.5 [Computing Methodologies]Computer GraphicsComputational Geometry and Object Modeling[Object hierarchies]
