Subject: RE: [plcs-tog] Tech Corigendum
I
would suggest that we only do the templates once, against the proposed corrected
version of the EXPRESS.
The Technical Corrigendum to the AP will require a new edition of the AP
module, plus corrections to other underlying modules. There is no
requirement for the new edition of the AP module to use the latest versions of
the modules that it references, although care should be taken to apply any
PLCS corrections to modules to the latest version if there have been
changes from other sources.
I
would however recommend that the PLCS corrections be documented as SEDS so that
they need to be taken into account by other developers.

Hi I would like the TOG to make a policy decision regarding the development of a technical corrigendum for PLCS.
We are in the process of writing a number of templates and implementing translators based on them.
As we do this, we are identifying some issues wrt to the PLCS EXPRESS. In the main this is to do with selects not being extended, but there are some other issues involving new entities.
The question is, how should we develop the templates?
We can either: 1)
Document the templates using the ISO
10303-239 ed1 EXPRESS, and point out the errors and provide work arounds (not
always possible). 2)
or correct the EXPRESS, document it
in DEXlib and state that if you are using PLCS according to the DEXs, then you
need to use the version on DEXlib. So, the question is "what is the policy advocated by the TOG"?
My view is that we should go with option 2 … and several templates have gone down this route.
Of course that means that we need to secure funding to develop the TC. However, that does not necessarily need to be done immediately, so long as all users of PLCS are aware of the fact that they need to use the DEXlib version of the EXPRESS Regards -------------------------------------------
