Again, only the abstract or ROA of the airplane using the VIN is named. An instance might have parts from different craft with mixed VINs. That's common in the automotive industry and probably the airline industry. The VIN gets you the assembly identity. After another few rounds of beating on this, it may become clear that is isn't possible to completely identify any real world (by that I mean dynamic, changing, multi-part) object with URIs with 100% reliability. This system is approximate at its very best. It names documents more reliably than real world objects, so the system is defined in terms of itself (the representations). Identity is a maintained value; not static. Humans have no problems with this. Machines may if you expect them to deliver 100% unambiguous results 100% of the time. The web is not capable of that in Trad or Sem form. Human language isn't capable of that. Roy is right. It doesn't matter. len From: www-tag-request@w3.org [mailto:www-tag-request@w3.org]On Behalf Of Jonathan Borden By such definition, although Mark Baker cannot currently be completely defined in OWL, such things as a Car, an airplane and/or various colors could be (e.g. the documentation for the Boeing 707 along with a particular "VIN").
