Validating YYYY-only FRBRdate values

[Greg Kempe]

Hello Akoma Ntoso fans,

The AKN Naming Convention for the IRI of a Work says that a year-only value (in the YYYY format) is a valid value for the date portion of a Work's IRI, and this must correspond to the value of the FRBRdate element in the FRBRWork section of the metadata.

However, the FRBRdate element's date attribute in the XSD schema is declared as: 

  <xsd:union memberTypes="xsd:date xsd:dateTime"/>

This doesn't permit a date that is just a year, so validation fails.

Can it be considered to add xsd:gYear to the union as follows, so it allows a YYYY-only date?

   <xsd:union memberTypes="xsd:date xsd:dateTime xsd:gYear"/>

Thanks,

Greg

Dear Greg,

this is definitely a good idea.

I see no problem in accepting it, and will suggest the TC to table it and discuss (and approve) right away.
