Re: [ontology-summit] Ontology Summit 2013

[Amanda Vizedom <amanda.vizedom@xxxxxxxxx>]

Not directly, I'd suggest. More precisely:

-- I agree with Steve's comments regarding the need to keep the focus *clearly* on evaluation, in order to have a sufficiently defined scope. The need for a clear and steady filter angle of approach for summit topics and sessions is a consistent summit risk-point.

-- To the extent that TOGAF/EA does come in an call for special attention, I suggest that it needs to happen organically, via the attention to evaluation.

-- That said, there are a number of ways it might happen organically. For one thing, depending on the use case, the suitability of an ontology often involves the match/mismatch between its provenance and its provenance requirements. Both of these can intersect importantly with the architecture.  For another, ontology requirements for a use case have many points of contact with the architecture. Finally, gathering and analyzing requirements, a step without which meaningful/predictive ontology evaluation cannot be done, is (notoriously) more often skipped than conducted, even in many cases in which some type of ontology evaluation is attempted. 

- So, architecture and evaluation clearly have implications for each other. It is surely going to come up in a number of ways. But calling out TOGAF, or other aspects of EA practice, IMHO should be done only as directly motivated by the evaluation focus as described, and with care to keep that focus central.  Same with SWE and KA methodologies and frameworks, I'm thinking...

John, Amanda, Michael,

Should consideration be given to injecting TOGAF
into the summit structure?

That's an important topic.  But the lifecycle of an ontology is
co-extensive with the lifecycle of any application or system that
uses or is based on that ontology.

This morning, I sent replies to two email lists that most people
on this list subscribe to.

 1. To Nancy W. on IAOA, I made the point that you can't separate
    the ontology of a system from its architecture or design.

 2. To Rich C. on Ontolog Forum:  "Imagine an IT department that had
    one group doing the architecture, a second group doing the design,
    a third group doing the ontology, and a fourth group doing the
    implementation."

I would relate that point to evaluation:  a critical issue in a good
ontology is its accuracy in reflecting the design and/or architecture
of the system.

There are aspects and modules that could be distinguished.  For
example, the complete ontology of a system might combine multiple
modules or microtheories.  But the complete ontology of a system
and its complete architecture must be closely coordinated.

Any evaluation of an ontology must address these issues.
