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). This will mean that we are using the current ISO standard However, it will mean that we are recommending an approach (via the work arounds) that we know will change
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. Having documented it on DEXlib, produce a TC against PLCS. This will mean that we are documenting the templates once. However, once we produce a TC, we may need to use some of the 2^nd editions of the modules. As no one from PLCS has being following the 2^nd editions technically, there is a possibility that the ARMs have changed. Furthermore, we need to avoid opening a pandoras box resulting in a lot of new stuff being added. Right now, there is no effort identified in the project to generate the TC.
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
