My feeling says that it would make sense to factor this
out of Document. What about using a dublin core class:
document.getDublinCore().getCreator()
This way, changes to the dublin core don't have to be
reflected in the Document interface and all its implementations.
And it would be a good basis for a GoF proxy implementation
of the dublin core which requires parsing the document.
What do you think?

So who's eager to do it?

agreed. It would also allow better reuse.

I guess Andreas just wants to make the interface generic and not
necessarily implement other standards beside Dublin Core. So I don't see
any reason to worry.

Of course, you're right. But is it just for the sake of it, or do
people really need other metadata standards? IMHO we should at least
think about extensibility and decide if it's worth implementing it.

Sounds reasonable. Could you point us to some of these projects?
Maybe we can start with a Metadata interface:
- MetaData Document.getMetaData()
- class DublinCore implements MetaData
The metadata classname would probably be added to the doctype
definition.

Although I am a big fan of DublinCore (it is after all better than no standard)
there are large groups of people out there who use competing standards to
Dublin Core. Please make it pluggable if possible.
