Title: RE: [plcs-dex] Assigning identifiers with no organization

Apologies if I have misunderstood but I am uncomfortable with this.  I thought PLCS had firmly established the principle of requiring the assigning organization in all situations.  If truly "the item being versioned provides the context information" then surely this would be the purpose of the ".id" attribute on Product_version?  Unless you are trying to say that multiple identifiers of version are possible in the context of the item and the identification assignment requires further context specification through classification (I can not think of a real example, I was going to suggest "design" versus "manufacturing" but that seems to be another example of different organizational contexts).

Cheers,
Tim.

Subject: [plcs-dex] Assigning identifiers with no organization

In assigning a version number, it is normally assumed that the item being versioned provides the context information (i.e. that the version number is effectively the second part of a compound key, the first part of which is the item number). Assigning version numbers should therefore use the template for assigning an identifier without an organization, and logically this template should be migrated to the assigning identifiers capability, rather than be in the assigning organization capability. Comments?

Additional Observations

Question to Business users: I have made the assumption that where multiple identifiers are applied to the same item, these do not independently define version numbers. Is this true?
