3. Adoption of agenda
Agenda adopted.
4. NDR document production (led by Mavis): brief
We agreed to various outline changes that would more accurately
reflect the principle of factoring out common rules into a
higher-level section.
We agreed that the NDR document should be written as a "true spec",
with crisp normative prose in the main text, and only references to
appendices containing position papers that contain rationales for our
decisions. So, for instance, the elements vs. attributes paper won't
be incorporate as such into the text; it will be included as an
appendix.
We agreed that we should include examples wherever possible, but to
say in the preface that examples are non-normative.
We deferred a decision on whether to include context methodology
information directly into the NDR document. One thing is certain:
The context methodology shouldn't be a bottleneck for NDR.
Mavis will continue to edit the draft and will talk to individual
position paper authors before incorporating text from them.
New ACTION: Eve to help Mavis with applying an "OASIS Word template"
to the NDR document.
5. RT/CCT discussion: 20 min
See the thread starting at:
http://lists.oasis-open.org/archives/ubl-ndrsc/200204/msg00005.html
We need a way of describing the semantic function of a piece of
information (RT), and then we need a path to the structure that
provides clusters of properties (CCT). The relationship is not
one-to-one, and thus we need the ability for each XML construct to
have an assignment to both. E.g., an element can be assigned an XSD
type corresponding to a CCT, and it can have a fixed attribute
corresponding to an RT (or its dictionary entry can merely reflect
this information).
Right now, the relationship between RTs and CCTs is nominally
many-to-one, but there are certain ways in which this breaks down in
practice. The proposal would make it many-to-many.
(The problem of capturing precision information sounds like it may be
a "hole" in the original CCTS analysis, so maybe it's not specific to
our work.)
If we really go in this direction, then the LC SC is likely to need
to identify an additional piece of information, in addition to the
RT, for each of their rows.
New ACTION: Arofan to attempt a more specific proposal along these
lines.
6. Filling in the tag structure holes (led by Mavis): 20 min
See the latest position paper at:
http://www.oasis-open.org/committees/ubl/ndrsc/pos/draft-arofan-tagspec-03.doc
We reviewed these, but didn't decide any.
New ACTION: Mavis to post each of the "live" issues to the NDR list
separately for email discussion.
