IM Chat Transcript captured during the session:

FrankOlken: I expect we will use the same teleconferencing facilities as usual on Oct. 30. Our audio tech will call into the teleconference

PeterYim: great, ... thanks, Frank

PeterYim: Howard: note: maintenance agency ... registration authority

FrankOlken: I think we want a maintenance agency (which has 					discretionary authority to approve new derived units).

FrankOlken: I think the maintenance agency should be something like NIST.

PatHayes: 1. Should we have a quantity model? Seems to be a majority agreeing that this is needed. 2. Explicit named units and Q. kinds? We can't do them all, how many will we do and what do we do about the others? Eg how do we relate to the UCM list? [Peter: maintenance issue arises when normative standard is formal. Who adds items to namespace/base?][Ed: yes, needs an authority or tool which can handle this. Not impossible and needs to be done. Certainly a scope issue.][Frank: exist 2 things. Extensions which are derived units, should be automatic. But also, new named units like 'watts'.] <>

PatHayes: Should have said, I was scribing Ed's speech above.

PeterYim: thanks, Pat

PatHayes: Ed: quantity kinds more promiscuous than units. Do we needs this is unbounded in extent.
 * kinds* of quantity kinds? Need to choose a level to stop publishing,

JoelBender: Is 'scale' a 'derived unit'?"

PatHayes: Ed: scales. Email discussions went nowhere. Do we have scales as part of the ontology? Unit conversions also an issue (4 so far). Other issues further out: uncertainty, tolerance. But these are v. complicated to do 'propoerly'. Do we need to handle these at all, if only crudely? Chips (eg) does, but its about measurement. Do we want to go this way?

PatHayes: Joel: I don't think so.

PatHayes: Ed: measurement is big area, need to bring other organizations in if we go there, eg UK NPL. Probably can't do it all, but also not completely omit.

PatHayes: Howard: need to consider target market for our ontology, to focus discussion. XXphilosophy..

PatHayes: Ed: priorities. We need to have a time limit, so some things are prunable. Final point: microtheories: not all extensions are mutually compatible, possibly. Up to us to provde guidelines for this situation.

PeterYim: EdBarkmeyer: OMG QUDV

SteveRay: Sorry, had to run to another meeting...

PeterYim: Ed will make an attempt to invite the QUDV leads, Roger Burkhart (John Deere) & NicolasRouquette JPL) to join us on Oct-30

EdBarkmeyer: Scope: assume quantity, quantity kind, SI named units, scales, conversion are in, measurement and uncertainty, specification and tolerance are less clear, it depends on our target audience and use, available expertise and time.

EdBarkmeyer: Big issue is extension: how to deal with the infinite list of quantity kinds and the very large list of derived units.

EdBarkmeyer: Pat: UML may be all that many will understand, OWL will be definitive for the Sem Web folk, CLIF is really the hard form for people committed to axiomatic definition and FOL reasoners.

EdBarkmeyer: Pat: there are other reasons to use CLIF -- it allows simpler consistent formulations of some complex notions

EdBarkmeyer: Frank and Pat discussed concerns about the arithmetic, use of functions like sine or square root. Pat: we want to stay away from floating point and arithmetic error.

EdBarkmeyer: The OWL folk have defined the datatype to be xsd:double, i.e., IEEE 754 numbers.

EdBarkmeyer: Pat: we want to assume mathematically exact numbers and avoid computational issues. Yes, actual uses may have some problems if the values and computations exercise the fringes of the computational behaviors. (Ed: the common problem is just that decimal fractions (the heart of metric) don't have exact binary renditions.)

PeterYim: Howard: sending our draft TC charter to Jamie and inviting him to do a 5 min. OASIS-101

PeterYim: @Howard - please consider the proposal of "QUoM" (as an 					alternative to "QUOMOS")

PeterYim: Joel: workplan slides - http://ontolog.cim3.net/file/work/UoM/UoM-standard-ontology_20091022/Trac-Motivation-and-Status--JoelBender_20091022.pdf

PatHayes: I also have to leave for another call. Peter, email me if you have any, er, tickets for me.

JoelBender: http://ontolog.cim3.net/cgi-bin/wiki.pl?UoM_Ontology_Standard_OASIS_TC_Charter_Draft#nid22D2

JoelBender: thank you

PeterYim: ref. getting buy-in from the standard bearers (e.g. BIPM) - Steve & Howard making advances on those fronts; Ed feels we will be more ready when we have a draft standard; Pat suggest using the now popular notion of "Linked Data" to position ourselves

PeterYim: great meeting, thanks, everyone
