Peter P. Yim: participants introduced themselves
Frank Olken: Howard mentioned the case of ton - which has multiple
definitions in differents systems of units. Worse, ton has several
different possible dimensionalities: ton as unit of mass, ton as unit of
power (for refrigeration), and ton as unit of energy (as in megatons of

Frank Olken: UCUM is being adopted by HL7 and Open Geospatial Information

Frank Olken: There is some argument about UCUM - it only considers units
not quantities. 9:14 am

informative versions available in OWL and UML, right?

Steve Ray: The advantage is that people can stay in their comfort zones
regarding development environments.
Frank Olken: RogerBurkhardt: QUDT also uses Object Constraint Language.
Peter P. Yim: 9:50am EDT - review / discussion on work-in-progress (draft)
Roger Burkhart: The QUDV model uses the OMG Object Constraint Language
(OCL) in combination with UML class diagrams to express consistency and
derivation rules such as dimensional analysis. The greater
expressibility of Common Logic could be important to express such
Joel Bender: As a follow up to my comment, I forgot to complete the
thought. When a document is presented in more than one language it
multiplies the amount of work that is needed to keep everything
consistent, and there is a danger that some constraint cannot be
represented in one or more of the languages. This is pretty obvious when
stated, but isn't always followed through very well depending on how
well the committee participants cooperate. Just a note of my personal
anxiety as the process continues.
Frank Olken: We are getting ready to resume the discussion here shortly
HansPeter_de_Koning: @Joel: I fully agree. Ideally we should have an
automated way of generating alternative informative specifications,
avoiding dependence on human transformations.
Pat Hayes: @Joel: I agree this is an issue we should be aware of. Just
baldly publishing several 'versions' would not do the job.
Peter P. Yim: 10:25am EDT now going into "Scope issues"
Ontology. see his slides linked from the meeeting agenda.
Frank Olken: First issue units of measure only, or also quantities. UCUM
has not quantities. NIST believes we need quantities.
Nicolas Rouquette: In the OMG, there is a specification called Query,
Views & Transformations, QVT, which provides support for specifying
mappings of an ontology to/from different representations in, e.g., UML,
OWL, RDF, etc... This approach is what the Ontology Definition Metamodel
(ODM) uses to specify the mappings amongst UML, OWL, RDFS and Topic
Frank Olken: Nicola Guarino concurs with units + quantities, also wants
reference frames for coordinates, etc.

Frank Olken: We need to talk about vector quantities to differentiate
between work and torque.

extend to vectors and tensors eventually. We should start with scalars,
but not preclude vectors and tensors.
Frank Olken: EdBarkemeyer: simply create base types for vectors but do
not explicate them further.

vector; rank 2 is matrix; rank > 2 is higher order tensor

Joel Bender: What is the chance that some user of this work will pick the
wrong label, or build a derived work, that uses the wrong class? What is
the consequence of picking the wrong one?
scope matters. I want to return to what the scope of the ontology.

Nicolas Rouquette: 1) Temperature of a Person: this is a general property
in the sense that a Person is a general concept. 2) Temperature of
Nicola Guarino is a specialization of the property: Temperature of a
Person. 3) Temperature of Nicolas Rouquette is a distinct specialization
of the property: Temperature of a Person. 4) We can then further
specialize the property to narrow the context in which we want to talk
about such quantities as properties of things in some context. 5) A
measurement model (In the sense of VIM) can impose additional
constraints on the context in which we can say that a quantity property
is measurable and then talk about a measurement as another kind of
property about a property quantity which is a property of something.

Frank Olken: EdBarkemeyer: count is another quantity kind.
and quantity role (length vs. height, width, ...)
HansPeter_de_Koning: According to VIM kind of quantity is NOT the same
as dimension - Dimension of a (kind of) quantity is the product of
powers of base quantities that you have selected for your system of
Frank Olken: Nicola Guarino: Two different quantities might have same
HansPeter_de_Koning: The VIM terms are "kind of quantity" and "quantity
Pat Hayes: @Nicolas: "specialization of a quantity" isn't a very useful
notion, as it has no way to be cashed out in any theories of quantity
relations. The temperature of Nicola (at a time, as determined by an act
of measurement) is not a specialization of temperature, it is a *value*
of temperature. It is not a property at all, but an actual temperature.
The property *temperature of person* is formally a set of pairs <x
y>where x is a person and y is a temperature. We have to allow
temperatures in this ('abstract') sense to *exist*, and when we do, they
suffice to say all that we want to say.
Nicolas Rouquette: @PatHayes: "Temperature of Nicola" is a Tensor; this
property is not tied to a particular context. We can specialize this
tensor, e.g., to refer to the "Temperature of Nicola on Oct. 30, 2009"
which isn't a measurement either.

Nicolas Rouquette: I said that, ideally, the UOM should really be an
ontology of VIM and nothing else. VIM has the benefit of having been
thoroughly vetted and reviewed in the scientific community for,
literally, hundreds of years.

Frank Olken: Some from European Space Agency has put us on hold and is

Frank Olken: EdBarkmeyers: We are discussing systems of quantities (not
yet systems of units).

Pat Hayes: @Hans-Peter: it was very entertaining.
Frank Olken: NicolasRoquette: QUDV can handle multiple systems of

units alone, as there could be different ways of measuring conductance

Frank Olken: chipMasters: We all want unit conversions.
Nicolas Rouquette: Earlier, someone expressed a concern about scoping how
much of "scales" do we want to tackle. I think that focusing first on
the notions of scales for which we can provide value-added reasoning
support (e.g., Hans-Peter mentioned automated conversion) is a good way
to force ourselves to limit the scope to what we can reason about.
