[Zope-CMF] Dublin Core's Relation implementation was:(Portal Topics as items' metadata)

[Ausum]

Just after posting my previous message I read more about this subject.
If I'm not wrong, it looks like DC's Relation element is still a work in
progress, and that a simple identifier (URL, URN, etc) is recommended
for this label, by the DCMI.

I think that within the context of the CMF, the Relation element, IMHO,
should be understood as one object's engine, and not just as a
collection of identifiers. Your idea, Seb, is good, but I think that
without the aid of artificial intelligence tools (which high-end CMSs do
have), every related resource must be found after an adjusted search, at
a per-object basis. As I see it (considering all the previous), a good
"related info" box should contain "stuck", previouly approved resources,
and "floating" resources as well. And all this seem to need a user
interface.

So the question still remains. How would you attach a Portal Topic to a
portal resource, as metadata?

Thanks again,


Ausum
