Dear Eric,Perhaps you should take a look at the EPISTLE Core Model. This
is an entity-relationship model (so precisely structural in your terms)
of some 200 entity types as an upper ontology - starting with thing,
supported by a Reference Data Library of some 10,000 concepts, aimed at,
but not limited to the Process Industries. This data model is already
being standardised by ISO in ISO TC184/SC4 - Industrial Data, as
ISO15926 (the data model is part 2). It is currently going through
pre-publication checks of the Final Draft International Standard.Some of
the draft material is available

     Subject: SUO: What the marketplace needs from us.    (05)

     My current role is in advising a particular portion of the US
     government in where to focus a few of its technological
     expenditures.  In that capacity, I have been getting to know a
     vast sea of data sets, tools, and legacy systems.  And I have
     formed the view that the most crying technological needs
     happen to be ones with which we ontologists can help:    (06)

     My customer needs to tie together large numbers of structured
     data sets into one seamless analytical environment.    (07)

     They need to share that seamless picture with other groups.    (08)

     They need a robust object model to support such a seamless
     environment.    (09)

     To that end, Iím not looking for, Horn clauses or free form
     axioms.  Iím looking for what I call structural axioms.
     Structural axioms specify the object-oriented subset of a
     logical theory Ė namely entities, type inheritance, other
     relations, relation argument typing (argxIsa), etc.    (010)

     They need an upper ontology from which to derive our object
     model.  To me, an upper ontology means chiefly the structural
     axioms starting with ďThingĒ and descending the inheritance
     lattice a relatively small number of levels.  The focus of
     that ontology is the actual domain entities such as people,
     events, places, but includes other entities and relations
     needed to properly specify and utilize the these domain
     definitions.    (011)

     Please give us the simple structural definitions with which we
     can model our domains.  Horn clauses are wonderful, but they
     havenít yet made much of an impact on the market place since I
     first encountered them as an undergraduate a couple of decades
     ago.  And if the marketplace isnít ready for Horn clauses, it
     certainly isnít ready for more sophisticated free-form axioms.    (012)

     In the commercial world, Iíve found the need to be the same.
     When Deborah McGuiness helped VerticalNet to set up their
     ontology group, she advised the same structural subset of
     logic.  Pat Cassidy and I worked in that ontology group
     (for Leo Obrst) where we oversaw and helped with the knitting
     together of multiple product catalogues into one seamless
     product picture.    (013)

     So Iím suggesting that if we are not focusing on structural
     axioms we are not giving the marketplace what it really needs
     or will soon fund seriously.    (014)
