The meaning is application dependent. For instance, Lotus Connections uses a category scheme value "http://www.ibm.com/xmlns/prod/sn/type";, which when used with a set of specific terms (e.g. "message", "bookmark", "chat", etc) has a very specific meaning in the Lotus Connections product.
Essentially, the scheme identifies the ontology to which the term belongs. - James Geoffrey Sneddon wrote: > > On 1 May 2007, at 19:28, James M Snell wrote: > >> The IRI has meaning, it just may not be dereferenceable. > > What meaning?
