Semantic data transformation plays an important role in realizing the vision of the semantic web. It supports the transformation of data in different representations into on-tologies. In order to allow the task to be achieved effec-tively, the instructions on how to realize transformation should be well specified, preferably in a declarative and re-usable format, thus allowing the construction of robust tools which on the one hand assist users to generate and maintain mappings at design time and on the other hand perform semantic data transformation at run time. Furthermore, the transformation instructions should not only allow the gen-eration of semantic data objects but also allow the creation of rich semantic relations between them. In this context, we developed a comprehensive instance mapping ontology. One distinctive feature of the instance mapping ontology is that it provides comprehensive support for the specification of complex mappings. Another feature is that the instance mapping ontology is representation independent, which does not limit itself to data sources in particular representa-tions. This ontology has been applied in generating a se-mantic layer for the web site of the Knowledge Media Insti-tute (KMi) at the Open University.
