''''Generate Atom'''
Inspire requires either WFS service or Atom xml for downloading datasets. These days governments are uploading xml-files as Atom-files and link to that document from the Geonetwork data download link. The Atom document contains roughly the same information as an Inspire iso19115/9 record in GN. So seems quite usefull to generate this feed document as an output format for Geonetwork.

{{{

}}}

Would return a document like:

{{{

'''Display Atom Contents'''
The atom link can be referred to from the Inspire iso19115 and Inspire iso19119 records in the catalogue

{{{
<srv:connectPoint><gmd:CI_OnlineResource><gmd:linkage><gmd:URL>http://.../geonetwork/srv/eng/ATOM?uuid=a3d33-...</gmd:URL></gmd:linkage></gmd:CI_OnlineResource></srv:connectPoint>
}}}

If GN finds such an atom feed url in the gmd:url field, the metadata record-view should get the feed contents and return the (metadata and the) hyperlinked documents inside the Atom document and present them as hyperlinks


TODO: 
 * create Atom output format (new metadata.show endpoint using custom xslt)
 * Add option to iso19115 'online resource' section to auto generate a hyperlink to an Atom feed referring to the uploaded dataset
 * Add option to harvest iso19119 metadata from an Atom Feed
 * If online resource section  contains atom link, present as human readable in metadata record view
 * Alter Geonetwork to comply with ETF Inspire Validation framework (http://www.geonovum.nl/dossiers/inspire/implementatie/conformiteit) for download services, without the need of editing xml-documents manually
