INSPIRE Pre-defined ATOM feeds

[etj]

Allow GeoNetwork to publish any local Service metadata as a pre-defined ATOM Dataset Download Service
The ATOM feed will encode as ATOM entries all the metadata records referenced in operatesOn elements.

We'll have 2 new services:

• atom.predefined.service: transforms a Service metadata in an ATOM "Download Service feed"
• atom.predefined.dataset: tranforms a Data metadata in an ATOM "Dataset feed"

These pre-defined ATOM feeds allow a catalog admin to expose as INSPIRE ATOM feeds only a subset of the available data. The set of the available downloadable resources is static: if other data needs to be made availble in the feed, the Service metadata shall be edited, and a new Data Metadata record shall be added in the operatedOn list.

This transformation of the ISO metadata into ATOM feeds can be performed on the fly, without the need to use the InspireAtomFeed* classes.

Minimum setup to test the PR:

• in Admin console/settings,
  • enable "INSPIRE" checkbox
  • in "Resource identifier prefix", set "id_" as the prefix (recommended, since the slashes in the default value may cause problems when creating internal links)
• create a metadata for data
  • create a resource id for the resource
  • add a downloadable resource, making sure that
    • "Function" is set to "download" (it's a dropdown menu)
    • "Application profile" is set to "ATOM" (it's a free text)
• create a service metadata
  • in the "Associated resources" panel, add a link to the previously created metadata
  • write down the UUID assigned to this service metadata
• change to privileges for both metadata, and make them visibile to all.
