The CMDI crosswalk must be reworked, to show the information correctly, as is the case in ufal.

I expect there are plethora of similar problems. We should make automated tests to see each file individually, or each collection, compare with current lindat, see the differences... Otherwise we cannot be even remotely sure this works. There are plenty possibilities for more edge cases that were not expected. This system is fragile. In certain places it can require special character, certain (most?) metadata fields cannot be duplicated and when they are, this error happens etc. etc.

Needs a lot of work to be even remotely confident in this functionality.

find out more, why, how, what are the possibilities

set max identifiers to more, to test all the items at once :) on top of xoai.xml
