Hi,

The open-source ontology registry/repository is a great idea. I am
thinking about it for some time. The way I envision it is to have a sort
of Ontology SourceForge that would provide collaborative tools to
develop ontology (versioning maintenance, search tool, editing tool,
reasoner, validator, semantic wiki, etc...). Such a web service would
provide a tremendous momentum to the SW activities. I am wondering if
W3C may be the right place to do this...

Best regards

An OWL version of such an ontology would be a "good thing."  Discussions
a while back on these lists, revealed that the XML derived semantics for
integers and floats in RDF are not what is wanted for such engineering
uses such as measured values.  Developing an open-source OWL-based
engineering math ontology is also a timely idea as there has recently
been talk of some 
of the high profile promoters of the semantic web directly supporting an

open-source ontology registry/repository.

For Semantic Web styled models in this area, have a look at David Leal's
work 
on an RDF(S) vocacabulary for quantities and units[1].  This reuses work
that 
was done as part of the ISO STEP standardization effort to support
information 
exchange of (manufactured) product data.  CIM/XML[2] may also include
models 
for units and measured values, although again these would be in RDFS.
CIM is a power industry standard and their control systems associate
somewhat richer metadata with measured values.
