W3C is reportedly discussing a proposal for a Semantic Web Activity
at its Advisory Council meeting this week.
A vote of the W3C membership will be conducted in December,
with a decision by the Director (Tim) in January.
W3C Proposals are members-only,
but a public abstract is being developed for IETF.
Last Week's Minutes
Frank van Harmelen had a minor correction; otherwise the minutes were approved.
EU Semantic Web Technologies Workshop
Ian reported on the
held last week in Luxembourg.
DAML and OIL were mentioned prominently.
Mike Dean brought up the concept of having standard language
constructs to describe ontology mappings, which has been
discussed during several of his visits to DAML technology
Having a standard set of language constructs would allow a clean separation
between tools to identify mappings and tools to execute translations,
and also provide a means to provide guidance to automated mapping discovery tools.
equivalentTo is a starting point.
Jeff Heflin discussed ontology mappings in SHOE.
Renaming and rules can cover a lot of the space,
but can't handle issues such as
unit-of-measure conversions (due to a lack of arithmetic).
Bi-directional mappings require 2 rules.
OIL uses an approach similar to SHOE,
but allows explicit uni- or bi-directional mappings.
The following people have confirmed their plans for next week's meeting in DC
- Tim Berners-Lee - ?
- Dan Brickley - ?
- Dan Connolly - yes
- Mike Dean - yes
- Stefan Decker - no
- Dieter Fensel - no
- Frank van Harmelen - yes
- Pat Hayes - no
- Jeff Heflin - yes
- Jim Hendler - yes (1/2 day+)
- Ian Horrocks - yes
- Ora Lassila - yes
- Deb McGuinness - yes
- Lynn Andrea Stein - no
There was consensus that it would be useful to schedule some
background briefings on SHOE, RDF/RDFS, and OIL, covering rationale,
debates, limitations, future plans, and other issues not found in the published
a Protege-like editor for OIL/DAML with a connection to a reasoning engine.
Jeff Heflin announced that his SHOE tools are now open source and available
Deb announced that Ontolingua and Chimaera now support input of
DAML-ONT, OIL, and RDFS.
They also support DAML-ONT output and could easily support
OIL and RDFS output as well.
Stefan announced an XMI to DAML-O conversion
We should see demos of these tools in DC next week.
There was consensus that we should defer publically announcing these tools
to www-rdf-logic until after we decide on upcoming language versioning next week.
