Include a reference to the INSPIRE Spatial Object Type in the dataset-level ATOM feed #3

Open stijngoedertier opened 6 years ago

stijngoedertier commented 6 years ago

According to TG Requirement 28, the ATOM feeds should include a reference to the spatial object type(s). <atom:link href="http://inspire.ec.europa.eu/featureconcept/ProtectedSite" rel="describedby" type="text/html"/>

The object types should be taken from the INSPIRE Registry http://inspire.ec.europa.eu/featureconcept

This information should be included in the dataset metadata record as a keyword #MD_KeywordTypeCode from a thesaurus. This must be documented in the code.

The spatial object type can be encoded using a gmx:Anchor element, as in the example below.

<gmd:descriptiveKeywords

The attached SKOS code list featureconcept.en.skos.rdf.zip can be imported into GeoNetwork as a thesaurus. It was converted from the RDF output in the INSPIRE Registry and converted into SKOS using this SPARQL query:
