Yes. And I'd add IBM and Apple to that list. Guha gave a talk
about Schema.org from Google's point of view, but it would be
good to have a broader overview of what Google does. (03)

I very strongly agree. Academics with no experience in mainstream IT
are incapable of designing tools that will be used in mainstream IT. (05)

I agree. The natural language texts written by people for other people
determine the real semantics of the SW (or the WWW). In fact, most OWL
ontologies have very little formal semantics -- the real "meaning" of
the OWL terms is buried in the NL comments. (07)

They're more than features. A better term is requirements. (09)
All the diverse methods that anybody has found useful are important,
and they should be supported. Tim outlined a strategy for doing that
in his proposal of Feb. 2000: (010)
http://www.w3.org/2000/01/sw/DevelopmentProposal (011)

I agree that there are many tools. But we need far more R & D
for developing ontology tools that are easy to learn, easy to use,
efficient to run, and interoperable with mainstream IT. (013)
The DAML final report of 2005 was very narrow in comparison to Tim's
original vision: (014)
From http://www.w3.org/2005/12/31-daml-final.html

> final stages of standardization, is for many people a key to the usability
> of semantic web data. (015)
That is *not* what Tim said about SQL. There is nothing wrong with
designing a YAQL (Yet Another Query Language), but it was hopelessly
naive to think that they could replace the language that runs the world
economy and the overwhelming majority of commercial web sites. (016)
DAML final
> we developed a stand-alone program to export an existing SQL database
> as RDF data on the web. (017)
That is *not* concurrent interoperability. It is an open invitation to
disaster to convert a mission-critical RDB to RDF. (018)

Google, Apple, Microsoft, IBM, Amazon, and other major vendors don't
use the DAML technology. That is a sign that we should consider it
a small subset of what humanity needs. (020)
KI

That's good. (022)
A combinations of DAML technology with mainstream IT and with any
other developments that anybody has found useful is important.
That is completely consistent with Tim's original proposal. (023)
Recommendation: Treat the DAML final report for what it is:
a research exercise. Tim's original proposal is a much better
statement of the SW goals and directions. That proposal should
be used as a guideline for future developments that support
interoperability among the DAML tools and all the alternatives. (024)
