Re: scientific publishing task force update

Following up to Phil's point, an alternative to building upper ontologies (UO) first, is to consider constructing a "Covering Map" between apparent overlapping sets of "related" ontologies. These are light weight, RDF associations that can help "pin-down" potentially related items/classes from different ontologies. I also agree the notion of "guides" is very powerful when dealing with a diverse community, yet trying to get things up and running sooner than later...

I've written this up on the HCLS/OntologyTaskForce wiki:
http://esw.w3.org/topic/HCLS/OntologyTaskForce/OntologyCovering

As BioRDF progresses in making more life sciences data available as RDF, we will have to deal with such ontological issues more frequently, so it's very useful for everyone to be discussing these issues at this point.

cheers,
Eric

Their paper did cause, how shall I say, somewhat of a stir.

If I were being cynical (those of you who know me will know how rare
this is), I would suggest that it's a case of "standards are so good,
that we need one each".

The issue is a slightly deeper one in bio-ontologies. It's not clear
that an upper ontology actually brings significant value to the
table. The claimed advantage of interoperability between ontologies
is, to my mind, somewhat bogus; they only really allow
interoperability when you are querying over the concepts in the upper
ontology. Much more important is that they help to ease the design of
an ontology; you have more idea where concepts should go, so you can
spend more time worrying about the details of what ever you are
modelling and less about the big picture.

On the flip side, they tend to complicate some stages of ontology
development, mostly notably the first month when you have lots of
biologists tearing their hair out trying to work out what a perjurant,
continuant, sortal, self-standing kind is.

The juries still out in my opinion.
