Open Grid Forum: Data Format Description Language Working Group

Weekly Working Group Conference Call
14:00 GMT, 16 July 2008


Attendees
Mike Beckerle (Oco)
Steve Hanson (IBM)
Alan Powell (IBM)


1. Go through actions
status updated below

003: AP is updating spec from WTX review and will produce a list of remaining unresolved items

007: Discussion about how expressions can be allowed in enumerated fields such as encoding. Simplest would be to convert enum properties to string but that wouldn't allow schema validation to catch errors.

2. Version 003 work items
The list of work items had been distributed and was discussed. Items requiring discussion will be converted to actions. Work items will also be tracked in this meeting.

3. Update to Decimal supplement
SH had distributed an updated proposal which was discussed. General agreement on the changes with the main point of discussion being the use of numberCheckPolicy to control the behaviour of the new numberZeroRep property. MB to review

4. Discuss lengthKind issues identified by WTX
Not discussed

5. Hidden proposal
Not discussed

6. AOB
Agreed an additional weekly  WG call is needed. MB to set up
