by Martin Westhead 06 Sep '05

06 Sep '05

Hi Folks, Does anyone have any items for tomorrow's agenda? I have: - Additional types (Bob's email) - Initial issues list (I will put this out later today) - Issues with draft (perhaps the authors or those commenting could pick some issues to discuss? If we can put them our in advance then others can review and prepare for discussion) Please send me (or the list) any topics, on the draft or otherwise, you'd like adding. Cheers, Martin

Comments on DFDL draft spec
by Steve Hanson 04 Sep '05

04 Sep '05

The draft is a big step forward for DFDL. Here are the initial comments from the IBM Hursley team. We have not reviewed all the Appendices yet, including the detailed properties list, but I am on a course all this week so I think it makes sense to send what we have so far to the group. (See attached file: IBM Hursley MRM team comments on DFDL draft specification Aug 2005.doc) Regards, Steve Steve Hanson WebSphere Business Integration Brokers, IBM Hursley, England Internet: smh(a)uk.ibm.com Phone (+44)/(0) 1962-815848

by Martin Westhead 31 Aug '05

31 Aug '05

***Note: next meeting will be _next_ Wednesday (7/11/05) 9am PDT*** * Present: Tara Talbot Martin Westhead Mike Beckerle Steve Hanson Geoff Judd Bob McGrath Jim Meyers * status reports from PNNL-NCSA project - open source status, progress on features? any proposals forthcoming? Have the go ahead for the source forge project. All that is left to do is to put the code up. Layering related work is still going on. PNNL are aiming to get some of the basic ideas into the primer. * planning for upcoming GGF15 - who is planning to attend in person Jim Bob Mike Geoff (?) Sumin (?) Tara (?) * Latest posted document - how do we structure discussion to this proposal? What do we do in advance of GGF15, what do we try to accomplish F2F at the GGF meeting. Issues list maintained by Martin. Issues show be raised initially on the mailing list and we will have a live document/spreadsheet on the website tracking the current status. * GGF15 sessions - so far I've only reserved one 90 minutes session as a work session. Presumably we also need another 45min session as community outreach. (Deadline is friday to reserve.) Mike will book another session. Outreach is becoming increasingly important. * AOB Bi-weekly calls to move to weekly starting next week. Tara to book extra telcons. Primer document from Bob was discussed, there may be something before GGF15. Mike suggested that there may be material from the current draft that should end up in the primer. Discussed the status of 'DFDL formal semantics' Bob and Martin interested in what Mike has done with this since December.

FW: Data files for DFDL
by Talbott, Tara D 04 Aug '05

04 Aug '05

Here are a few of the sample data files that we have worked on and their xml translations. I believe that these are examples of files where it would be difficult to achieve the desired translation without some form of layering. premix.bin - a binary file from the chemkin program. Contains three different sections, determined by a header value. In the solution section there is a sequence of x values, the values were combined with a sequence of points containing a temp value and massFrac values. test.prp - a text-based file based on a nwChem format. Contains some header info, then a list of field names, then a series of frames with values that should correspond with the field names. When translating, the list of field names is read as a layer and later referenced from the frames. clayers.bin - same as example of layers shown at last f2f, creates a sequence of 100 complex numbers from a file containing a sequence of 100 real floats then 100 imaginary floats.

today's call - nobody on
by Mike Beckerle 20 Jul '05

20 Jul '05

ok, so it's summer time and the livin's easy. I was on the call, nobody else came on. Quick status of IBM Westborough DFDL project: 1) we have data-source indirection kicking over in our prototype. We're pretty happy with how this is coming out. The feature seems simple enough to explain and the implementation is of acceptable complexity. We're still pushing to have a proposal for the group by end of july. 2) we are working on a proposal for annotation syntax which will reconcile differing viewpoints within IBM. Still on track for a proposal to the broader community by end of july. ...mikeb
