materials for possible discussion during session 2
by Mike Beckerle 30 Jun '05

30 Jun '05

Two slides about DFDL I presented at the Data area summary - Session 1 pre-slides - before the presentation. Session 2 doesn't really have any slides (just a title slide) This represents work on the annotation syntax/model. We took a clean-slate approach to a model for the rep properties with an eye towards enabling annotations "something like" the OMG CAM-model instances approach. Very rough work, but since we might be able to have a conference call today I thought I'd forward these for consideration.

I've uploaded notes and slides from the F2F, and as promised a zip of the examples we walked through from the Ascl (now IBM) prototype my group is working on. In this zip is testCase.xsd, which is the schema of the test-case files that we're using. These are a common format that we could all share for tests of a variety of implementations. http://forge.gridforum.org /projects/dfdl-wg/document/F2F_2005_05_Examples_and_XSDs/en/1. is the URL for the zip file. Sorry for the delay in getting this all up on gridforge. Mike Beckerle Architect, Scalable Computing IBM Software Group Information Integration Solutions Westborough, MA

Hello everybody!
by Yi Zhu[MSc] 08 Jun '05

08 Jun '05

Hi, My name is Yi Zhu. I am a MSc student of EPCC, majoring in High Performance Computing. I am here because my final project is about DFDL (I am sorry for that as the project has just begun, what exactly will be implemented has not been decided), and I believe this is a interesting, challenging and promising field. However, I am a real beginer in DFDL, so I need all your help. Thanks ever so much! Regards, Yi

Conference Call on 6/8
by Mike Beckerle 03 Jun '05

03 Jun '05

Unfortunately I can't make the semi-weekly conference call on 6/8. Go ahead without me though! I have the following to report in no particular order of occurance or relevance: 1) MikeB did review ideas on layering and compositionality with Jim Myers. Went well. Jim was supportive of the approach. We have a bit more to do conceptually, but I'm very optimistic right now that we'll be able to advance something to the whole group which will be crisply defined and meet needs without excessive complexity. 2) scoping proposal from F2F was written up and posted to grid forge. Only saw one supportive comment from Martin Westhead. I'm pretty sure this matches what we discussed at the F2F and would only ask that people at least verify if it matches what they expected. 3) other F2F materials were posted on grid forge. Slides, notes, and the testcases and schemas we looked at. Of note, the testcase schema was posted. This will help us all share test/use cases as we move toward having working implementations. 4) Suman sent his latest properties model. Here in westborough we're getting close to where we'll be able to take a look at this. Bear with us Suman, we appreciate your effort, it's just taking some time to get there. 5) I am going to GGF14 in chicago. I've requested two sessions on DFDL there. One to be status/overview as usual, one to be a working session w/conference call if we can swing it. I hope we'll have time before GGF14 to get some more proposals up on grid forge, though we can't ask for any formal comment on anything by GGF14 because we're past the date for that sort of thing. I'm still hoping to have something more on (1) and (4) above in hand (posted to this mailing list or gridforge) before GGF14.
