[step-manufacturing] [EXTERNAL] Re: Reminder final call and report of AhG3 on UUID's

[Swope (US), Kenneth A]

Just to weigh in here from the Chair perspective.  An Ad Hoc Group can only provide a report and recommendations.  It can not dictate requirements.  Those come separately.  The reason I am pressing for this report to be published formally is to get those recommendations out to the full committee for the necessary dialogue and consensus building.

I am pressing for the final report to be as complete as possible to help facilitate this level of transparency and to capture all the hard work I know that the project team has invested into the content.

Martin,
On a personal note, I have held off until the last possible time to commit the information model into AP 242 ed4, after the software implementors have expressed strong interest in implementing the model, and after detailed analysis by Asa and long discussions with implementors.

The AHG3 proposal does not say what you have stated in this email.

Readers of the proposal interpret the proposal as AHG3 is dictating a specific solution that ISO 10303 needs to implement.


The slide deck provides an illustration of maps between UUIDs.  A map is a relationship between UUIDs. The Stakeholders want to manage those maps.
In order to manage the maps one needs to record information about those maps.
