If we really want to achieve that systems talk a common language for
interoperability and data integration, then we should develop and use a kind of
Formal English (and other formal natural language variants) in which the
semantic rules of the formal language are defined. This requires a managed
formal dictionary-taxonomy. (01)
Such a Formal English should also provide a universal Formal Language structure
that can be used as a universal data structure to harmonize and integrate
industrial databases. (02)
An example of such a language is as Gellish English
(http://en.wikipedia.org/wiki/Gellish_English). (03)
But that might be too disruptive.

Very well said. I'm including this post and the DAML proposal as required
readings in my Semantic Analysis Methods course as of tonight. (06)

I am *very strongly* in favor of disruptive technology. An example
is the WWW. It revolutionized everything. But it *built on* and
*extended* legacy systems in the best possible ways: (010)
1. It built on the Internet and TCP/IP, which was a legacy that
started out as Arpanet in 1969. (011)
2. It developed HTML, which was based on SGML, which is a legacy
from IBM's GML (Generalized Markup Language) from 1969. (012)
3. Tim Berners-Lee was inspired by using Apple's HyperCard, which
was a proprietary application that was inspired by the Hypertext
idea that Ted Nelson proposed in the 1960s, which was inspired
by Vannevar Bush's Memex article from 1945. (013)
4. By 2000, almost every commercial web site was built around
a relational database. Big sites used Oracle or IBM DB2.
Smaller sites used LAMP -- of which the M stands for MySQL. (014)
In 2000, Tim B-L wrote the DAML proposal for funding to build the
Semantic Web. Tim did not want to replace legacy systems. Instead,
he proposed to extend the WWW and the existing applications that
used the WWW. Please read Tim's DAML proposal: (015)
http://www.w3.org/2000/01/sw/DevelopmentProposal (016)
In that proposal, the keywords are 'interoperability', 'heterogeneous',
and 'diversity'. That would have enabled commercial web sites to work
with semantic tools in a smooth migration path. (017)

The database world was talking about semantics and ontology long
before Tim proposed the Semantic Web. In Tim's DAML proposal,
he definitely supported interoperability with relational DBs. (019)
Unfortunately, what you have been hearing is the decidability mantra.
None of the legacy systems are decidable. But they are powerful
enough to run the world economy. In comparison, the decidable
systems are just toys. (020)
