Download Service feed contains links to dataset metadata records

Purpose:

For each entry, the Download Service feed must provide a link to a Dataset metadata record. This link shall have a "rel" attribute with a value of "describedby" and a "type" attribute with a value "application/xml". The link must point to a Dataset metadata record, to which the Service metadata record refers (contains a link to). There must be exactly one link for each entry.

Test method

• Resolve the describedby link to get the metadata document of the service

For each entry:

• the link to a Dataset metadata record must be a valid HTTP URI
• there must be only one link to a Dataset metadata record
• resolve the link to a Dataset metadata record to get the Dataset metadata record
• test if the Dataset metadata record contains a root element /gmd:Metadata
• test if the dataset identifier in the Dataset metadata record is present in the metadata document of the service and in the Download Service feed

Test type: Automated
