This thread raising DAML+OIL was reassuring to see in this context, and Sean's
added ref. to WebONT.

I confess that it's easier to go forward with  a few embarrassing "can you
explains" (as you'll find below) after having duly tried to RTFM, than to lurk
in partially informed silence.  Hence, I'll be the guy who was sleeping when
the teacher gave the assignment and digress with a few points, begging folks'
indulgence.

A couple of simple questions, some acronymical:

Which EARL (the second one?):
EARL  Electronic Audit Research Log
EARL Enhanced Address Recognition Logic

Which FOPL?
FOPL Forty-One Hundred Port Log (USCG)
FOPL Frequency of Primary Line

And this makes better design sense, to build upon those standards "classes"
which multiple ontologies can inherit and extend, e.g. RDF Schema & Model, and
derive the resulting association of the respective ontologies (DC, other KM
stuff, whatever) is syntactically enabled from the design foundation, rather
than back-mapped at the mere semantic level.

Following above, this would furnish the HumanML syntax matrix for inherited
and extending ontologies.

Will these hints and tips be made available to this list and/or the net?

I did think I understood QName and local name resolution for namespaces (at
least from the XSLT and XPath perspective of addressing and transforming
them), and so I'm having to confess a little uncertainty about which "model"
you mean the namespace/QName is not preserved in . . . the DOM?  That doesn't
make easy sense either b/c QName, local name and namespace (as an @ value) are
addressable nodes.  So, as noted above, I'm gonna go ahead and be the "duh,
um, uh - I don't get this" guy on this list.
