Hi Folks,
I have taken this version below and posted
a version 018 of the draft core spec. My changes are in the section “What
is DFDL” I have drafted this section and moved it into the Introduction
at the top. I have also added a section on “What DFDL is not” and I
have made a start on the v1.0 scope. All of the changes are fairly rough and I
suspect that the Introduction section is now too long and could do with some
editing.
Thanks,
Martin

Subject: [DFDL-WG] New internal
draft of Core document
I've posted version 017 of the internal draft core
spec. to the gridforge site. Here is the URL:
https://forge.gridforum.org/sf/docman/do/viewDocument/projects.dfdl-wg/docman.root.current_0/doc14407?_message=1177035246251
I'd
like to ask people to review it with an eye towards whether the semantics part
is clear enough or at least getting there.
The
major accomplishment in this draft was folding together some of Geoff's
material on defaults/nulls/missing/optional (especially the input flow-charts)
into the parse-strategies technique so as to illustrate that the
parse-strategies framework I had put in was capable of handling this
complexity.
This
spec is really now getting to the limit of what I can do in MS-Word. I.e.,
there's too much stuff in here that really needs to be developed as code in a
programming language to insure there are no errors in it. Assuming the
semantics framework is now ok, the next work is really cranking out actual
parse and length strategy and conversion definitions, and this is going to be
very error prone unless done in some type-checked and executable form.
