[pycsw-devel] Constraint parameter

[Tom Kralidis]

(FYI I inadvertently replied offlist, sorry)

Hi Adrià: This was happening in the absence of an ISO <-> DC mapping for this use case (i.e. querying csw:Record, asking for ISO back).  I've committed the ISO to DC serializer in the code (and at the same time ended up refactoring the csw:Record serializer, which was occurring in two places -- thanks!).  Can you test this and let us know if this works for you?

Thanks much for testing and feedback!

..Tom
