RE: [plcs] Proposal for DEX Template

All,

Just a comment/concern from someone not involved in the workshops…

I note that the “assigning identifiers” capability is 26 pages in Word. I also note that DEX000 includes 10 capabilities.

Extrapolating from those two facts, it appears to me that DEX000 is going to require something in the neighborhood of 200-300 pages of documentation.

Doesn’t that seem excessive given that it’s just a parts list? I can’t imagine the reaction of an implementer not involved in the PLCS development when he or she has 300 pages of paper dropped on their desk for something so basic. I checked and the entire AP203 Edition 1 Recommended Practices document from PDES, Inc. is 110 pages and the PDM Schema usage guide is 271 pages and each covers far more scope.

I also can’t imagine their reaction if they’re not already literate in EXPRESS and Part 21 as that’s all the diagrams and examples show, but that’s another question. I’’ just reiterate my disappointment that the DEXs are not proving to be a means for bringing PLCS and STEP to a broader audience.

Cheers,

David

Subject: [plcs] Proposal for DEX Template - D000

All.
Unfortunately we have some problems with the CVS upload of DEX D000 to DEXLib. We try to sort this out. In the meantime we have converted some of the files into Word documents which are attached to this mail. Following files are attached:

o DEXLib Introduction, please read this file first!

o DEX D000 – the “DEX Template”

o Capability “assigning_identifiers”

The "DEX Template" document is all new documentation in DEXLib. Information added to existing documents in DEXLib are marked out with yellow.

Please note that the added documentation is meant as proposal only. Please feel free to comment!

<<DEXLib Introduction.zip>> <<DEX000.zip>> <<Capability C001 assigning_identifiers.zip>>
