OGC API Records / API improvements #59

Closed fxprunayre closed 1 year ago

fxprunayre commented 1 year ago

/items support DCAT output.

Before that change, DCAT output was only provided per records and not for search results.

Downloading a large catalog in DCAT format

curl -v "http://localhost:9901/collections/main/items?f=dcat&limit=12000" > rdf.xml

Made some changes to DCAT mapper to not fail on invalid dates.

Add DataService mapping for services.

Check DCAT-AP validation using https://www.itb.ec.europa.eu/shacl/dcat-ap/upload

/items and /item support GeoJSON output.

/conformance added

Thanks @fxprunayre Does it replace the old https://www.datagrandest.fr/geonetwork/srv/fre/rdf.search service ? Which means GN could be harvested by data.gouv.fr ?

Does it replace the old

It could probably be considered as an alternative.

BTW data.gouv.fr should probably rather support harvesting GeoNetwork 3 or 4 using CSW and its DCAT output (see https://github.com/etalab/doc.data.gouv.fr/commit/f8a0b32f19f46c22c30add1bfa5cda248861531e#r75959289) which is probably the more standardized way to get the catalogue content as DCAT (that we are providing for years now - see https://github.com/geonetwork/core-geonetwork/pull/1407). rdf.search was more a quite old internal/experimental API (see https://trac.osgeo.org/geonetwork/wiki/proposals/DCATandRDFServices). OGC API Records is still a draft.

Ok thanks for the precious inputs. I'll take a closer look on that. Cheers

Hello,

I have cloned your branch. Thank you for your job. I've noticed that the conversion to dcat is still not developed for large catalogs. I've done this locally. Are you interested in my contributions ?
