how do ogc-api link-types map to pycsw link types?

[pvgenuchten]

Current behaviour of pycsw for rel="xxx" of ogcapi item links is: if a link contains rel, then this link is taken

https://github.com/geopython/pycsw/blob/3fefd4e7ac53346e21a259f437316ea97c3004c8/pycsw/ogc/api/records.py#L1236-L1241C11

Not sure how the value is populated (but that is a follow-up of this thread)

Recommendation 9 in https://docs.ogc.org/DRAFTS/20-004.html recommends to use a rel from https://www.iana.org/assignments/link-relations/link-relations.xhtml

Is some mapping required between link types used in for example iso19139/dublin core to these ogc-api types?

[tomkralidis]

How does ISO 19115 deal with link relations? Or does it still deal with gmd:protocol per se?

We have to verify this behaviour in -3, at which point we can decide on our plan in pycsw (via update to geolinks.
