Qualified DC in OAIserver

Description

Enhance the OAI server to work with qualified dublin core.

* Need to find or define a schema for qdc, as the OAI specification doesn't include one. * Make it an option to the server - currently we only support one metadata set I think, so need to make sure that we can add another one.

* There are schemas defined for rfc1807, marc21, oai_marc (see  http://www.openarchives.org/OAI/2.0/guidelines.htm). Think about these when doing this.

* If we support qdc, does this mean it needs to be available for all sets (= collections)? Or can individual sets support different metadata sets?

All collections that you want to serve using our oaiserver must provide a mapping to DC. If a collection happens to have qdc metadata, then make the server use that (if qdc was requested).

I assume that dc is a subset of qdc??

I have done most of this.

The new metadata set is called gsdl_qdc. It uses dc prefix for elements.

Still to do:

* Restrict output to elements actually in the set. Need a list somewhere that names all the elements. For all sets. * Remove the qualified name from the element. eg CoverageSpatial should become spatial in the output. * mapping in oai.cfg - need to have separate mappings for dc and qdc. Since they use teh same element ns, we need to change the mapping rules to use teh set name instead. ie oaimapping dls.Title oai_dc.title and modify the code accordingly.

This is all done now except the bit where we need to turn dc.Coverage hat Spatial into dc.spatial

  • status changed from assigned to closed
  • resolution set to fixed

I have finished this now :-) Just needs other people to test.
