Closed vocabulary for field values?

[JohnMrziglod]

Which of the field values in the B2Find metadata defintion need to be restricted by a closed vocabulary? For some fields, contrary to free text, a more closed vocabulary would be suitable, since less options look better in terms of representation of facets.

Fields that could be assigned a closed vocabulary:

• discipline (choose from predefined list)
• language (use predefined set)
• format (mime type could be argued)
• country (the current definition could be more restricted)

Note: the fields regarding temporal information and coordinates could be excluded from the definition, since these already have to conform to strict rules.
