CSW harvester OutputSchema config support #258

[ccancellieri]

This will close #258 adding support to an additional param into the csw json config:

"output_schema": "mdb"

mdb is the namespace of the schema to use (in this case it's an iso19115-3.2018)

{'mdb':'http://standards.iso.org/iso/19115/-3/mdb/2.0'}

Full Example below:

{
"user":"ckan_admin",
"cql": "dc:identifier = '0-----292--------------------------'",
"output_schema": "mdb",
"default_tags": [ ],
"default_extras": {},
"group_mapping": {},
"read_only": false
}

Doing this the CSW harvester will receive the metadata in the configured outputschema (must be supported by the target csw server).

This is great :) Do you need any help with this PR?

[frafra]

I get this generic error after applying this PR (rebased on master) : Error contacting the CSW server: can only parse strings. I think there is a problem with the changes made to the __init__ function of CswService.

Ciao @frafra thanks to look into this. I think something bad could happen here:

https://github.com/ckan/ckanext-spatial/blob/b82eb89244ddfc640be8811572e730c2ea3b94a9/ckanext/spatial/lib/csw_client.py#L210

Would you be able to check the response provided by the server?

I'm apologize but I'm not using this plugin anymore, I changed approach, so my help can be very limited on this.

@ccancellieri I think you are right, I will look into that. Which approach have you taken, If I may ask? I am interested into harvesting data from GeoNetwork too.

Please search for json and geospatial keywords under ckan discussions ;)
