Here are my comments and some in-line editing on the I actually think the primary reason to push this document forward is NOT extensibility, but because it is needed to clarify the basic semantics of DFDL. That is, it allows us to make very clear exactly what properties in the annotations are guiding the selection of which conversion functions. ...mikeb Mike Beckerle STSM, Architect, Scalable Computing IBM Software Group Information Integration Solutions Westborough, MA 01581 voice and FAX 508-599-7148 home/mobile office 508-915-4767 "Westhead, Martin (Martin)" <westhead@avaya.com> Sent by: owner-dfdl-wg@ggf.org 01/23/2006 04:58 PM To <dfdl-wg@ggf.org> cc Subject [dfdl-wg] More documents These are documents 3 and 4 of a set of 3 :). The documents are: - bundles ? a reusable block of DFDL statements - Conversions ? a proposal for the semantic details as to how conversions are chosen during the operation of a DFDL parser. These semantics include a description as to how the conversions can be extended. These documents round off the current set of proposals from the extensibility design team. The team has reasonable consensus on these documents, with the (relatively trivial) exception of bundles where there may be some outstanding issues. We believe that with these two documents there is enough material to support the necessary extensibility. However, we have not yet worked through enough examples of round tripping to understand whether that is sufficiently well covered and we are expecting that all the ideas in these documents will require refining by the group as a whole. I would like to discuss these two documents on Wednesday (if possible).
