Sure, I was just paraphrasing (SW). But I would distinguish between the 
'map
and the territory' (phrase by Korzybsky). Otherwise, in ontology 
language,
we could say, TheWeb is aKindOf Map. The web is the territory, the
ontology is the map. The Meta-Ontology carries the addresses of all the
micro-ontologies (including the ontology of Ontology) scattered all over
the territory on various servers (maybe). Schemaweb looks like they
are doing a good thing by being a repository of schema. But they
should agree on terms (schema or ontology - while both words have
other meanings in cognitive science and philosophy).    (01)

I'll hold off on the OM Ontology MOO discussion for a while... I think  
that is
absolutely doable. It's just the 'navigation' of an OWL file:    (02)

You are in AnOntology, its very complex in here. Obvious exits are:
North to KnowledgeSpecification, South to DAO.

Danny is sitting at his computer.
@say 'danny, what are you doing here, I thought you were going to the
party in ComputationalLinguistics tonight.
@build ComputerMusicOnotology South (making a subclass of 
DigitalArtOntology)
@go South
@viewCode (gives you the code for the new class just created)
@addProperty "xyxyx" (distinquishes ComputerMusicOntology from parents)
@etc.    (03)

Why do this? For an ontology designer to become 'involved,' like a work
of art, you would like to make the class 'AudioSample' a keeper - an 
object
of durability/eternal, or until magnitudes are no longer specified by 
numbers.
Its not top-down or bottom-up design - its inside-out.

The Getty Vocabularies are done at:
http://www.getty.edu/research/conducting_research/vocabularies/aat/
But of course Art and Music ontologies like Art and Music curriculum 
only
go so far toward our needs in digital arts, right?    (04)

Also I have posted my Protege project file  (just a test) - it has some 
DAO
concepts that are connected to the standard upper ontology.
http://dao.cim3.net/file/pub/testProtege/
and http://dao.cim3.net/file/pub/testHtml/ for the exported html of 
that project.
This is just a test for sharing data for this project.    (05)

I think we might agree that working on small ontology units and using 
merge
functions is great. But, there are also big  problems with working 
bottom-up
(no inheriting a bunch of helpful material from the upper ontologies).
More on that much later.    (06)

Let's make 'scope' another thread - as it's certainly a key topic. But 
the
comment on the Getty vocabularies is part of the answer.    (07)
