A.06.IR511.TGR6.linkToMetadataForTheService.md

Provide a link to the metadata record for the Download Service

Purpose:

The Download Service feed must provide a link to a metadata record, that describes the Download Service. The link must be at the feed-level and have a "rel" attribute of "describedby" and "type" attribute of "application/xml" or "application/vnd.ogc.csw.GetRecordByIdResponse_xml".

Test method

• check existence of the describedby link that refers to the metadata document
• resolve the describedby link to get the metadata document of the service
• the metadata document must be a valid XML document
• the metadata document must have a valid gmd:MD_Metadata element as the root element
• the metadata document must have a Resource Locator
• the Resource Locator must resolve to an Atom Download Service Feed document
• this Atom Download Service Feed document (refered from the metadata document) must contain a describedby link that is the same as the describedby link of the first step

Reference(s):

• IR NS, M1, section 2.2.1, Download Service Metadata parameter
• TG DL, Req 6
• IR MD, section 2.2.4

Test type: Automated

Notes

Note 2: the INSPIRE language request parameters in the Resource Locator to the Atom Download Service Feed URLs must be ignored in the comparison.
