I think this note by Dan Brickley covers much: http://rdfweb.org/mt/foaflog/archives/000047.html The essence of this note is pretty much encapsulated by this couple of paragraphs: [[ Just as missing out information isn't wrong, nor is adding more information. From an XML perspective, it is both tempting and natural to see this as a too liberal and free-form. XML encourages us to think about this problem in terms of tags: "what tags can appear inside a foaf:knows? is foaf:Person allowed? what about wordnet:Programmer?". Unfortunately that doesn't scale well, since it requires a painful amount of coordination amongst the parties defining these vocabularies. RDF was designed to expect the unexpected. You don't need anyone's permission to invent new tags, or to have your tags 'go inside' their tags or vice versa. This is hugely liberating, particularly for FOAF because so many problem domains overlap in this space, and life is too short to spend in standardisation committees arguing about XML schemas for dictating whose XML tags enclose whose. ]] The Internet brought us the possibility of networked applications that span the world. RDF extends this world-spanning possibility to application data as well, by allowing the data itself to grow. #g ------------ Graham Klyne For email: http://www.ninebynine.org/#Contact
