Hi all,

I agree with theses exchanges, and thanks a lot Don for your so quick update.
The best we can you now is to have the GB as easy  to use and understandable as possible for future PAIS users.

Hi Bob,

Thanks.  Unfortunately for this point, the PAIS standard is already published so the best we can do now is make it clear in the companion Green Book.

Model ID and version must be managed together by the same entity.  In other words, when the Model ID is a CCSDS defined quantity, like CCSD0015, then the version can only be updated by CCSDS.  Otherwise there could be ambiguity as to what Model specification was being identified.  I believe we should have made this explicit in the standard. Therefore if an Archive wants to enforce any change from that in the PAIS, even just making an optional element mandatory, it will need to generate its own Model ID and manage related versions.  My updated text on this issue in the recent Core document is not this explicit and I propose to update it further when I complete section 4.5, unless we don't have agreement on this view.
