[mailto:rob.bodington@eurostep.com] Hi Here is a summary of the points about AP239 ed2 made on the
conf call First some background: 1)
AP239 ed1 published 2004 – call it
ap239_iso_ed1_schema 2)
DEXlib developed – some changes to
ap239_iso_ed1_schema call it ap239_oasis_ed1_schema were made. 3)
Av DEX + Task DEX has been published for ballot with
ap239_oasis_ed1_schema 4)
AP239 ed2 in development – call it
ap239_iso_ed2_schema 5)
Av DEX + Task DEX have been balloted, but not yet had
all ballot issues addressed The question is, at what point do the ed2 changes get rolled
back in the schema. On the call 4 approaches were described: 1)
Remove the changes to ap239_oasis_ed1_schema and
make DEXlib use ap239_iso_ed1_schema ·
Existing templates will have to change ·
Software implementation will have to be updated
to reflect the changes 2)
Allow no changes to ap239_oasis_ed1_schema and publish
the completed Av DEX + Task DEX with ap239_oasis_ed1_schema. In parallel
develop DEXlib2 that addresses some template issues, and brings in the changes
from ap239_iso_ed2_schema ·
No existing templates change – we ignore a
number of the ballot comments ·
No change to Software implementation at this
stage. They continue to use some complex mapping and misuse reference data. ·
DEXlib2 will change templates ·
Future software implementation will have to
change to use the new edition of dexlib - DEXlib2 3)
As part of the ballot resolution for the Av DEX + Task
DEX, bring in some of the changes with no compatibility issues on
a case by case basis: ·
If the changes have no compatibility issues,
i.e. new entities or select extensions, incorporate the change and create
ap239_oasis_ed2_schema which is part of the Av DEX + Task DEX publication ·
In parallel develop DEXlib2 that addresses some
template issues, and brings in all the changes from ap239_iso_ed2_schema ·
This should not impact existing templates.
New business templates may be created, but no new OASIS templates. ·
Software implementation will have to accommodate
new entities i.e. read them, but as no new oasis templates, not be required to
do anything with them. ·
Future software implementation will have to
change to use the new edition of dexlib - DEXlib2 ·
4)
As part of the ballot resolution for the Av DEX + Task
DEX, bring in some of the changes with compatibility issues ·
change and create ap239_oasis_ed2_schema
which is part of the Av DEX + Task DEX publication ·
In parallel develop DEXlib2 that addresses some
template issues, and brings in all the changes from ap239_iso_ed2_schema ·
Some template changes ·
Software implementations change – but will
be more stable in the long run 5)
Make DEXlib use ap239_oasis_ed2_schema
·
Rework of templates Regards -------------------------------------------------------------------------------- Eurostep
