Of course, we're already using an extension for this. But the question is whether these elements are useful enough to others that they should be a added to the ZeeRex schema (version 2.1?) > On the other hand, I think that the zeerex context set is not the > place for those fields to be searchable from. Is there a problem > with creating a new context set for them? I think it would be silly to make a new context set to hold indexes used for searching elements in the ZeeRex record. What would you call it, the ZeeRex2 context set? :-) But I agree that, as always, we should re-use indexes already defined in other sets if they exist. > For country: dc.publisher?
