CSW GetRecords supposed to return csw:SummaryRecord instead of dc:metada?

Deer deegree team,I am using GeoNetwork 2.4.1 to harvest CSW records from our deegree 2.3pre (August 2009) build and I am encountering dificulties due to what may be a bug in deegree_csw. Geonetwork sends a GetRecords request with <csw:ElementSetName>summary</csw:ElementSetName> but without an outputSchema. The default outputSchema for a GetRecords request is http://www.opengis.net/cat/csw/2.0.2. deegree returns dc:metada but apparently the response is suposed to be csw:SummaryRecord. I looked at the CSW 2.0.2 specifications again but I am only more confused now. Following is the thread I kicked off on the GeoNetwork developer forum. I hope the GeoNetwork folks make more sense. Ciao, Wolfgang -------- Original Message --------
hello Wolfgang, François, and list : I've looked at it a bit more with Jose Garcia, and we found : (1) GeoNetwork did not send a outputSchema in its GetRecords request. This means that the default per the CSW202 spec should be used by the deegree server, which I think means we should receive results of type csw:SummaryRecord, as says François; (2) GeoNetwork should actually put a "more preferred" ISO outputSchema in the request, if the Capabilities advertizes it (as does the deegree server's Capabilities). Jose is committing a fix for this to GeoNetwork today; (3) GeoNetwork can only handle GetRecordsResponse that contains SearchResults of type csw:SummaryRecord (CSW) or gmd:MD_Metadata (ISO). Other types, like the dc:metadata receivede from deegree, leads to the message "Skipped record not in supported format :" you got (4) sending GetRecords requests to the deegree server with various outputSchema I get : outputSchema="http://www.isotc211.org/2005/gmd" --> response: ISO records, correct outputSchema="http://www.opengis.net/cat/csw/2.0.2" --> response: dc:metada, expected response: csw:SummaryRecord <absent outputSchema> --> response: dc:metada, expected response: csw:SummaryRecord Hopefully things are more clear ?

Correction:>From what I understand, both csw:SummaryRecord and csw:GetRecordsResponse responses should have DC formated metadata if no ouputSchema is defined. However, should a GetRecords request with a "summary " ElementSetName return a csw:SummaryRecord response and not a csw:GetRecordsResponse response?

Heikki Doeleman posted at [hidden email]hi Wolfgang, the tests I did were already using your URL at http://75.101.143.247:8080/deegree-csw/services. For good measure I tried them again, both with your online CSW client that you mentioned and with another HTTP client tool (Poster), yielding the same results : outputSchema="http://www.isotc211.org/2005/gmd" --> response: ISO records, correct outputSchema="http://www.opengis.net/cat/csw/2.0.2" --> response: dc:metada, expected response: csw:SummaryRecord <absent outputSchema> --> response: dc:metada, expected response: csw:SummaryRecord So if I'm not mistaken, a bug in the deegree CSW server is that outputSchema="http://www.opengis.net/cat/csw/2.0.2" is not handled correctly. Maybe you do handle the case of a missing outputSchema correctly in the sense that you treat it as "http://www.opengis.net/cat/csw/2.0.2" which would explain that we get the same results ? As for the contents that should be in the output when outputSchema is absent or is "http://www.opengis.net/cat/csw/2.0.2", it definitely still should be a csw:GetRecordsResponse, but one that inside its descendant csw:SearchResults contains a list of csw:SummaryRecord elements (and not as it does now, a list of dc:metadata elements). Inside those csw:SummaryRecord elements I would expect dc: formatted data, yes, starting with a dc:identifier or a dct:bibliographicCitation element. For the full spec see the CSW202 schema at http://schemas.opengis.net/csw/2.0.2/CSW-discovery.xsd. Does this make sense ?
