Adobe's use of RDF

XMP Lowdown "Adobe looks very strongly committed to XMP. Their decision to make it an RDF-based format, the high profile that Adobe products have in the commercial publishing world, and big print media publishers' growing interest in efficiently tracking their metadata are three factors that combine to make XMP a golden opportunity for the business world to appreciate the value of RDF. This business community doesn't care much about the Semantic Web, and its use of XMP (and hence RDF) will be behind firewalls, but an increased use of XMP in PDF, JPEG, and other formats will eventually mean more files with RDF-based metadata sitting on publicly accessible web servers, and hence a greater extension of the Semantic Web."
