Fw: location of the complexEndian example
by Mike Beckerle 06 Dec '05

06 Dec '05

Strange. I sent this some days ago, but it bounced back today complaining about the domain in dfdl-wg(a)ggf.org. Here is is again. I'll try gridforum.org domain this time. ...mikeb ----------------------------------------------------------------------------------------- >From our call today, people asked where the complexEndian example went.... On gridforge, this zip file document https://forge.gridforum.org/docman2/ViewProperties.php?group_id=113&categor… contains files named testComplexNum1.* and testComplexNumTypedef1.* Those are the files with my original mock-ups about extensions to add a "complexEndian" attribute. ...mikeb "Westhead, Martin (Martin)" <westhead(a)avaya.com> Sent by: owner-dfdl-wg(a)ggf.org 11/30/2005 01:12 PM To <dfdl-wg(a)ggf.org> cc Subject [dfdl-wg] Telcon Notes Present ------- Mike Bekerle Tara Talbott Martin Westhead Geoff Judd Steve Hanson Bob McGrath Reports from Active Trackers ---------------------------- Scoping tracker is being worked on - no news. Extensibility group is moving forward - nothing to report yet Discussion of Geoff's documents ------------------------------- Variables doc Mike observed that variables could be used in place of his extensibility proposal on annotations. Martin asked about whether we wanted to include this in the standard. Is the complexity worth the addition - the feeling of the meeting was probably it was. Martin proposed that instead of binding a variable value to an element, the variable value should be set with an XPath expression. Discussed the question as to whether the variable value can be reset, whether it can/should be scoped in the same way as annotation attributes. Next step will be for Geoff to revise the document to look at cases where value may need to be reset and start to explore some of the semantic issues involved. Choices doc Discriminator type - what if discriminator is not a string? For efficiency can we handle discriminators that are integers? Suggest that instead of discriminators being computed to strings they are computed to an XPath value with its implied type so that numeric discriminators do need to be converted to strings. Wildcard docs Group seemed fairly happy with this proposal as it stands.

RE: [dfdl-wg] Updated versions of the Variables in DFDL, Supporting Choices in DFDL and Supporting wildcards in DFDL documents
by Westhead, Martin (Martin) 30 Nov '05

FYI here is a summary of XSLT variable semantics: http://www.stylusstudio.com/w3c/xslt/variables.htm#variables It would be nice if DFDL variables turned out to have either compatible semantics or a subset of them.

Wednesday's telcon
by Martin Westhead 23 Nov '05

23 Nov '05

Hi Folks, Usual reminder for the usual meeting, except last week we finished our first pass through the issues list. I believe that the next piece of process should be to review progress on all of the tracker items. It would be useful to agree priorities and dependencies for them. Perhaps a good place to start would be the documents that Geoff sent out today. Unfortunately I cannot join until 9.30 so I would be grateful if someone could take notes for me? Thanks, Martin Conference call instructions: Number: 1-800-664-0771 At the automated answering system, press 0 for the operator. Ask for the "Daffodil working group" call.

Proposal for the use of Variables in DFDL
by Geoff Judd 22 Nov '05

22 Nov '05

Hi, Attached is a document that describes a proposal to use variables in DFDL. This came out of discussions on tracker item 1699 (Parameters and keying). I have also updated the documents on Choices and Wildcards to incorporate variables. Any feedback would be appreciated.

However it has now been brought up to date and all the new trackers have been added.
