Agenda & Proceedings

1. Meeting called to order:

2. Roll Call:

  • see above
  • new participant introduction (as required)

3. Key items for review and discussion today:

3.1 Opening: - by Michael Grüninger

The objective of this workshop is to address the following questions:

are required to support the OMV use cases?

These are empirical questions that we can answer, given some effort.

3.2 Discussion:

  • From the 2011.03.18 "OOR Metadata Workshop-I":
    • 1. review Ken's use cases to validate the adequacy of OMV - near term
    • 2. research, discussion, sought expert advice on state-of-art on versioning, identifier, etc. - medium term
    • 3. drive the sandbox to production box transition - urgent
    • Specific question for the OOR Team:
      • Why do we believe that extensions to OOR are needed?
        • What use cases do we have in OOR to motivate such extensions?
        • Has anyone in OOR used OMV? If so, what issues have they encountered?
  • continued discussion and exploration of the above ...
  • explore what resources are needed to carry this work forward, and solicit volunteers
  • [OT] (optionally) ... if we have some extra time, we might spend a few minutes to see if there are questions about the OOR-Logo

anonymous morphed into MariCarmenSuarezFigueroa

MariCarmenSuarezFigueroa: Bodil Nistrup

JouniTuominen: As a reference, in ONKI we describe ontologies with following metadata:

http://www.seco.tkk.fi/u/jwtuomin/tmp/onki-ontology-metadata.ttl

JouniTuominen: When we designed the metadata schema, we weren't aware of the OMV. It would be

reasonable to make it OMV-compatible, by using OMV properties when possible, and extending it when

necessary.

MariCarmenSuarezFigueroa: do you have documentation about those metadata? Any document, or figure?

Mike Bennett: Just a heads-up: we have started joint work with the OMG on Semantics Repository

standardization; a major component is how to socialize the middle/upper ontology content. We would

expect to leverage OMV terms.

Michael Grüninger: What metadata do we require to support modularity?

Michael Grüninger: What extensions to OMV are needed to support additional ontology representation

languages such as Common Logic?

Mike Bennett: We are still working out what is the best formal approach - at present we've got

placeholder terms for most content, will look at how to align with external ontologies. In

particular, not ontology-level terms but terms about terms (SKOS type of terms etc.).

Tim Darr: This is the only relationship between ontologies that we would be interested in. We

typically decompose our ontologies as taxonomies, relations, and rules.

Tim Darr: A query, it seems to me, should match against the "composition" as opposed to the

individual components.

Peter P. Yim: [action] JouniTuominen will do a comparison of the ONKI metadata schema with OMV and

report back (at the next workshop)

Michael Grüninger: @Tim: The modularity I was thinking about is along the lines of an ontology that

combines a time ontology, a product ontology, and a business process ontology, which in turn extends

a generic process ontology. How are all of these ontologies related to each other?

Tim Darr: @Mike Is that different from the OMV import relations?

Mike Bennett: THe kinds of ontologies we are looking at include UN-FAO, REA, XBRL (probably XBRL-GL),

OWL Time, OMG's Time model,

Tim Darr: OMV provides a way to list the ontologies that are imported

Mike Bennett: Future one would include GeoNames, any ISO standards that are

ontologies;

Peter P. Yim: maybe we can take MikeBennett's use cases ... and see if OMV suffices (or what extensions

are necessary to meet his needs)

Mike Bennett: Units of Measure

Mike Bennett: Action on me: Define Use Case

Mike Bennett: @Michael at 14:33 this is very much our use case

Michael Grüninger: @Tim: In COLORE, we make distinctions between conservative and nonconservative

extensions. In the latter case, some modules allow the entailment of new axioms

Mike Bennett: I am working through an example with the REA ontology to see what approaches work best.

Tim Darr: Use vs. extend, for example?

Mike Bennett: I have a draft paper on that which might be useful.

Tim Darr: Yes

Tim Darr: That sort of ontology-to-ontology relationship seems to me to be useful: what you are doing

with the ontology that you import.

Mike Bennett: Our challenges are two-fold: The SR ontology adds decorative terms (Archetypes) which

are not an OWL concept, and it disposes all high level terms under 3 top level lattices. So most

(not all) external ontologies which have owl:Thing at the top, would be redisposed under the

Sowa-derived lattice

Michael Grüninger: Would it make sense to focus on a particular domain or a particular set of

ontologies such as time?

Mike Bennett: Time ontology efforts: W3C time; OMG draft work; Mayo Clinic (Cui Tao, paper at ICBO in

Buffalo in July); FpML derived time terms; our own draft terms

Mike Bennett: Pat Hayes: Catalog of Temporal Theories

Mike Bennett: One thing we are thinking of is separating business domain specific (Legal, Accounting)

versus domain neutral things like time and math and units of measure which are not related to any

industry

MariCarmenSuarezFigueroa: Related to TimDarr's comment: with OMV you can describe the relationships

between two ontologies (imports, versions, compatibility); and if more are needed OMV can be

extended.

Peter P. Yim: In the interest (and urgency) of our need to stand up a "production" instance of the OOR

... noting that we only have a "sandbox" instance of OOR now, and that the key differentiation

between the two is the implementation of "Gate Keeping" which, among other things, *requires* anyone

who uploads an ontology to OOR to populate the metadata (which is not required for the OOR-sandbox -

Question: can we just go ahead and implement the "Gate Keeper" with OMV (as is) or (we here, take

the time to) specify a "minimal required subset" ... can we discuss this?

Mike Bennett: Tree analogy: mid level is under-specified. things like legal, country, legal entity,

are owned by some industry but are terms which other industry need to refer to (financial:

securities are contracts; insurance: risk etc.

Michael Grüninger: @MikeBennett: Which of the ontologies that you mention in your chat posts can be

submitted to OOR Sandbox?

Mike Bennett: @MichaelGruninger the thing that can be submitted at present: OMG time work when this

is done. The Mayo work definitely. Need to deduplicate these two

Michael Grüninger: Action Item 1: Focus on time ontologies as a testbed for exploring relationships

between ontologies

Ken Baclawski: The OMV would have to be extended to deal with the gatekeeping metadata such as the

owner, group, status, rights, etc. I noticed that the onki ontology has some properties dealing with

these issues.

MariCarmenSuarezFigueroa: Metadata such as status, developers, rights, etc. are also covered by OMV.

We can analyse which ones from ONKI are not covered yet by OMV.

Mike Bennett: Accounting: XBRL and REA which have related but different terms and ontological

commitments

Tim Darr: How about something like SPIN?

Michael Grüninger: Action Item: Contact GaryBergCross (SOCoP) to contribute geospatial ontologies to

OOR Sandbox

Mike Bennett: Geographical ontologies would be a very useful area to align and cross reference

ontologies (for instance UN-FAO has very specific scope; ISO 3166 has no axioms;

GeoNames?...

Mike Bennett: Geographical is a good one to focus on because it is more like an "industry" vertical

(there are expert bodies, standard bodies etc. specific to it) but it is a set of terms which almost

any ontology will need to refer to (securities; buildings management; etc.)

Mike Bennett: And if anyone wants to be involved in the OMG joint work drop me a mail

Peter P. Yim: Next session: Fri 5/20 "Architecture & API - V" ... then Fri 5/27 "Metadata III"
