[GeoNode-users] Documentation for CSW

[Israel López]

Thanks so much Tom, your information is very useful.

I've tested it, but I have two observations in the ISO query:

1. In keywords (maybe it was type error), I could get it but without the
number "2"
at final of the query, i. e.

print csw.records.itervalues().next().identificationinfo[0].keywords

2. For the TopicCategory, I can't get it still. The returned value is an
empty array.
I attach an image.

when I get the ISO metadata via geonode interface, using this:

http://ide.adesur.centrogeo.org.mx/catalogue/csw?outputschema=http%3A%2F%2Fwww.isotc211.org%2F2005%2Fgmd&service=CSW&request=GetRecordById&version=2.0.2&elementsetname=full&id=63444cf2-f984-11e4-89e1-0050569122ab

I can see that the category is there, and I know that the resource have it.

I don't know if a parameter is missing to query the full metadata or
something else.

> Hi Israel: thanks for the info.  This should work.  Notes:
>
> - in the default CSW schema representation, keywords are represented by
> 1..n dc:subject elements.  You can access this in OWSLib via:
> csw.records.itervalues().next().subjects
> - Categories need to be set in the UI or provided via ISO metadata (which
> supports a TopicCategory element), and are then available via querying the
> CSW for an ISO schema representation, i.e.:
>
> csw.getrecords2(outputschema='http://www.isotc211.org/2005/gmd')
> print csw.results
> print csw.records.itervalues().next().identificationinfo[0].topiccategory
> print csw.records.itervalues().next().identificationinfo[0].keywords2
>
> Having said this, there is currently no way to express the Category in
> the default CSW schema provided by pycsw.  I've filed a pycsw issue [1]
> to fix this for cases where the core CSW schema is the preferred option.
