    Abstract An extension of the Dublin Core Collections Application Profile DCCAP suitable for representing context dependent collection level metadata is presented in this paper The extended model called Multidimensional DCCAP is based on a multidimensional extension of RDF Contexts are specified by assigning values to a set of appropriately chosen parameters called dimensions The proposed extension allows the user to encode metadata for each defined context enriching substantially in this
