Semantic Documents - Example for CCTS-Based and RDFa-Annotated XHTML Documents

If heterogeneous information systems store documents to the ontology-based document repository, they have to provide ontology-based documents (i.e. semantic documents). In this paper, we present how ontology-based documents (XHTML+RDFa) can be provided. The RDFa markup is used for embedding exchangeable information in the RDF format within the XHTML documents. Before we can provide ontology-based documents, we have to specify the data model. In this paper, we introduce how we modeled CCTS-based data and how we formed the RDF repository which supports the CCTS-based data. Our example is from the National Project for IT in Social Services (Tikesos) which main aim was to specify the ontology-based national archive to improve the interoperability of client data in diverse information systems.
