The reference XSLT implementation of GeoDCAT-AP has been moved to:

There is XSLT support now in pycsw master #761 so the GeoDCAT-AP XSLT can be configured to work directly with pycsw.

[Kate-Lyndegaard]

Can anyone provide a configuration example or additional documentation on how the GeoDCAT-AP XSLT can be used directly with pycsw?

[tomkralidis]

A minimal approach would be to define a DCAT output schema plugin, followed by an XSLT configuration to the DCAT XSLT.

[Kate-Lyndegaard]

Thank you, @tomkralidis. I will give that a try.
