Metadata dataset: Resource Locator / Check that at least one resource locator is defined.

[fxprunayre]

"A Resource locator linking to the service(s) providing online access to the described data set or data set series shall be given, if such online access is available." does not mean that all gmd:onLine/gmd:URL have to be "valid" URLs.

Report about the expression used to check the URL as it is a bit
restricted vision of what an URL is eg. file://, jdbc://, PRL starting
with // are not considered valid.

Proposal:

• Check that at least one URL is following the expected pattern
• If none found, report error with the pattern used

Changes available in inspire-eu-validation/ets-repository@144aaad

When no valid URL provided, then message is now:

XML document 'file.xml', record 'c651bc41-d5da-49de-ba47-c51eabbb2007': No online source
 element found in the record following the rule 
'(http://|https://|ftp://)([a-z0-9]{1})((\.[a-z0-9-])|([a-z0-9-]))*\.([a-z0-9-]{1,4})(/?)'.

I am not sure about this change proposal. Given that there are on-going discussions in the MIG about using the resource locator element more extensively, I think this should be discussed with the 2017.4 sub-group.

Hi,
I understand this is still not yet solved or fully addressed, considering our current discussions about the use of resource locator and the alternative linking approach, but has there been any advance on this particular issue?
