[pycsw-devel] CSW Distributed search question

[Jose Garcia]

Hi all

I'm checking to implement DistributedSearch for GeoNetwork and the OGC
specification seem not very complete related to how to return results. I
have check pyCSW as it's implementing it to see how has been managed and
seem like this:

- Supposing local catalog and a federated one.

- A GetRecords query is send with startRecord=0 and maxRecords=10:

   - Local node matches 12 results, so should return the first 10.
   - The same request is send to the remote catalog, that matches 24
results, so returns recordsMatched=24, recordsReturned=10

*  - Local node aggregates results and returns: recordsMatched =36,
recordsReturned=10, nextRecord=11 and returns local and remote records (20
in total)*

I understand why returned the total records (20), otherwise when requested
startRecord=11 and maxRecords=10, if only returned 10 in first request, the
other 10 will be not returned in any way.

Did you find about this behaviour in some other spec document or you just
decided it was the way to go?

Also not a big expert in python, so hope no misunderstood the the code and
also the problem described is clear.

Thanks in advance and regards,
Jose García
