Thesauri are possible building blocks of a web of linked data. As DBpedia for large data sets in general, specialized thesauri could be useful as interlinking hubs for professional communities – if they are available on the linked data web. The paper describes the conversion of a large economics thesaurus to RDF/SKOS, using the enhancement mechanisms of SKOS to dispose some non-standard features of this thesaurus. The deployment, using RDFa pages, and the interlinking with other resources, namely a library catalog, and an experimental mapping to DBpedia are presented. For information retrieval support, a SPARQL query facility uses the data for building a thesaurus-backed terminology web service
