Subject: Re: Special meeting to discuss NDR VER8 and VER9
A meeting was held 2005.04.08 to discuss the versioning problem.
ATTENDANCE
Jon Bosak
Tony Coates
Stephen Green
Arofan Gregory
Eduardo Gutentag
Anne Hendry
Sylvia Webb
KEY FINDINGS
- There is a real problem here that is independent of schema
generation (i.e., it would exist even if the changes were made
by hand)
- The problem arises when changes are made simultaneously to two
or more items sharing the same namespace
- The suggestion to limit minor version changes to XSD extension
doesn't solve the problem
- If we can't figure out a way around this then we will have to
abandon polymorphism within the limits of XSD as a goal
PLAN
An ad-hoc team composed of Arofan, Stephen, Tony, and David
Kruppke will work over the next two weeks to analyze this
problem in detail and recommend a solution. All other
interested TC members are invited to participate.
Key questions:
- Is it possible to preserve polymorphism?
- If so, how?
- If not, what do we recommend instead? (The default is
redeclaration of the whole set.)
- In either case, what changes need to be made to the NDRs and
the Customization Guidelines?
The team will hold phone meetings from 18h00-20h00 Central
European time (17h00-19h00 in the UK) on 4/12 (Tuesday), 4/15
(Friday), 4/18 (Monday), and 4/19 (Tuesday) using the usual UBL
conference bridge. (Subcommittee chairs: please notify me ASAP
if this conflicts with any of your scheduled calls and we will
switch to an alternative number for these sessions.)
Email will be used to exchange examples. To ensure the widest
possible participation, mail on this subject will use the TC
mailing list. All messages in this thread will begin with
"[ver]" to distinguish them from other mail. Arofan will be
copied on all such mail by including the address
"ilg21@yahoo.com" on the cc line.
Initial action: Arofan to review the examples posted earlier by
Stephen at
