Re: [ontolog-forum] Foundation ontology, CYC, and Mapping

["Matthew West" <dr.matthew.west@xxxxxxxxx>]

Dear Sjir,

 

This was a conceptual data model, so attributes were not a focus. However, ISO 15926 and the Shell DDM were designed to be  data driven, so there were very few attributes. Most things that would usually be modelled as attributes were modelled as relationships to entity types. So the model was meaningfully instantiable.

 

Regards

Dear Matthew,

 

Very interesting figures.

 

Could you tell us how many properties or attributes were associated with the 1700 entity types?

 

Kind regards

 

Sjir Nijssen

MW: As another example, about 5 years ago when I was still working for Shell
I was charged with developing a conceptual data model for Shell's Downstream
business (oil tanker to petrol pump). We started with ISO 15926 as a
foundation ontology, and developed a 1700 entity type data model in 12
months with a team of ten people. This would normally just not work:

 - A team of ten people will usually fail to agree on how to model things,
 - If you let ten people model independently different areas they will come
up with incompatible models,
 - If you have a team of 2-3 people it will take a lot longer than a year to
produce 1700 entity types.

Because we had a foundation ontology that we had confidence in as an
analysis framework we did not suffer these problems.

I presented the project at a DAMA conference and one of our major
competitors was present. After the presentation I asked what they thought
such a model would cost them to develop. They said $5m. It actually cost
$1m.

Whether foundation ontologies play much role in reasoning, is I think rather
to miss the point.
