[wg11-owl] Goal of the review

[David Price]

Hi Gerry,

I actually didn't mean "four current uses" but "four potential uses" so the
current content of 15926-4 doesn't come into it. I don't object to spliting
3 into ontologies and information models. However, we'd need a definition
that explained the distinction. On terms, are we comfortable with saying
domain-specific (e.g. STEP) information models are for unambiguous data
exchange purposes and domain-specific ontologies are for reasoning over a
set of assertions? Then we'd have:

1) modeling universal semantic repositories (e.g. 15926 data warehouses)

2) modeling taxonomies used to classifcy content related to databases and
data exchange (e.g. OASIS PLCS)

3) modeling domain-specific information models for exchange (e.g. as an
alternative to STEP)

4) modeling domain-specific ontologies for reasoning (a new use case)

5) as an implementation technology for EXPRESS-based models (a new use case)

There's likely a little overlap but we can probably ignore that for these
purposes.

Cheers,
David

David:

The actual 15926-4 RDL part consists mainly of a taxonomy.  So I think that
a "general purpose, universal semantic repository" is more of a goal than a
reality at this point, at least with regard to the published standard.

What about OWL as a replacement for EXPRESS as the SC4 information modeling
language?  I'm not in favor of using pure OWL as a modeling language, but it
should be discussed.  Perhaps a UML stereoptype for SC4 (requirements
currently captured in EXPRESS) with a mapping to OWL would be more useful.

Maybe you intended that to be covered by 3, but I do not think that all of
our information models are "domains-specific ontologies".

Regards
Gerry

As a start, there are multiple ways in which OWL might be used by SC4. As
OWL is built on RDFS and RDF, it may also be appropriate to consider some
use of those languages as well.

Seems like there are at least four uses:

1 - As a language for defining general purpose, universal semantic
repositories similar to what 15926 provides for the Oil and Gas industry.

2 - As a language for defining taxonomies to be used with the External_class
modules in STEP, etc.

3 - As a modeling language for domain-specific ontologies (i.e. schemas) as
done in STEP today, Mandate, etc.

4 - As an implementation language with the concepts of Class, Property and
Individual, standard XML and other encodings, industry query languages, and
industry APIs.

1, 3 and maybe some cases of 4 enable the use of reasoners, etc. too.

Anyone think of any other uses?

To my knowledge, OWL is not "deployed" anywhere in SC4. It is being used in
OASIS standardiziation for use 2 with AP239.

Hi all, 

Dave> "SC 4 requests WG11 to conduct a review of the deployment of OWL
Dave> technology in SC 4, with contributions from the other WGs, and 
Dave> make recommendations for its consistent use."

Based on the original SC4 resolution, I would expect the end result of these
discussions to be a brief WG11 white paper summarizing the current usages
and your feelings on where things should go.  Obviously, Spain is 
a bit close, but hopefully you can have something by the next meeting.

Cheers,
