R17b: Additional adjust minOccurs to prevent semantically unclear expressions. #20

Closed pdpinch closed 13 years ago

pdpinch commented 14 years ago

PBCore currently allows confusing structural expressions such as Producers since many of the primary elements of the PBCore containers are not themslves required within the container (additionally the schema's comments and minOccurs statements frequently contradict each other on whether an element is required or not).

Need more specific recommendations.

The creator, contributor and publisher elements, within their respective containers, now have minOccurs="1" as of 3fcbe9d4de685c36301d3e1ab86c99b12ae06773

I believe this addresses the issue.

Hold up a minute on this. You might not know who is the creator, contributor, or publisher so you'd have to leave them empty. For example an orphan work with no visible means of identifying any of these things. Or I might be the sole creator of a media asset, in which case there are no contributors. Or an asset might not yet be published, or even never published in which case there is no publisher. I don't see how it's confusing to leave these as minOccurs=0, and I believe making them mandatory will lead to worse confusion/frustration.
