Dear Deborah, (01)
Just to tie this up for people not in the know... (02)
> The International Alliance for Interoperability has changed its name to
> building SMART international http://www.buildingsmart.com/. Another
> relevant ISO standard to add to your list is 16739 Industry Foundation
> Classes (IFC). Here is part of a diagram for referencing classes in IFC
> http://ontolog.cim3.net/file/work/BSP/FPML/IFC2xObjectDiagram%23141B04B
> .jpg. Please also see the Model View Definitions at http://www.blis-
> project.org/IAI-MVD/ for IFC data exchange, ideally supported by the
> IFD.
>
> There are a number of chasms and gaps in the connections from the IFCs,
> to the IFD, to EPISTLE and related standards. (03)
[MW] The EPISTLE work is standardised as ISO 15926 of course. (04)

> The International Framework for Dictionaries (IFD) (ISO 12006-3)
> standard is developed by ISO TC 59/SC 13/WG 6. Many of the members
> of the work group are also members of International Construction
> Information Society (ICIS ). The IFD standard has many similarities
> with the EPISTLE standard for the Oil and Gas industry.
>
> While the IFC standard describes objects, how they are connected,
> and how the information should be exanged and stored, the IFD
> standard uniquely describe what the objects are, and what
> properties, units and values they can have. IFD provides the
> dictionary, the definitions of concepts, the relationships between
> them and the common understanding necessary for the communication
> to flow smoothly.

>
> That diagram uses relations with the following names: 'is a type of',
> 'is a part of', 'consists of', 'can be', and 'relates to'.
>
> Those five relations by themselves (including the catchall 'relates
> to') provide a gross level classification, but they aren't sufficient
> for detailed reasoning. However, they are very important for
> searching, classifying, and natural language analysis and
> disambiguation.
>
> That level of detail is certainly insufficient for designing doors that
> can be interchanged among different buildings. Those details, however,
> have always been stated in very low-level specifications, such as
> traditional blueprints or CAD/CAM programs.
>
> Those two levels of specification are typical of every field:
>
> 1. A gross-level classification with very few relation types and
> few if any axioms.
>
> 2. A precise, extremely detailed specification that can support
> extended reasoning, computation, construction, and assembly.
>
> At the gross level, there is very little difference between an ontology
> and a terminology. The detailed levels are where all the complex
> reasoning and computations are carried out.
>
> If our ontology proposals are to be useful in practice, it is essential
> for us to recognize those two levels and incorporate them in any
> proposed standards or guidelines.
