As the number of RDF Schemas increase, it is becoming more and more
difficult to create complex RDF (such as the XHTML to RDF conversion stuff)
without referencing a huge quantity of namespaces. I'm starting to think
that it may be better if for a very complex RDF system, one created a single
namespace that includes synonyms (using "isDefinedBy" and "equivalentTo"
properties) for all of the separate namespaces and properties/classes
therein that one uses. To some extent this cannot be done because languages
like RSS have (prose) structuring, but if I needed one property from each of
ten namespaces, why not just create another RDF Schema that contains
synonyms for them all and use that as the only namespace?
As to the more structured stuff (RSS, EDL etc.), I'm not sure that there is
any easy solution to mix them, becasue as yet they don't have any form of
Schema that defines how they can be mixed. However, if they did have Schemas
(XML) that would be a piece of cake as well, wouldn't it?
My 2p worth...
