When I send a CSW GetRecords request to my Geoportal from my custom client, I find that only certain fields are returned in the CSW response, that is title, abstract, identifier, etc:
The question is: how can I add new fields ("returnables") to the CSW response? There are plenty of other fields that could be returned, such as hierarchyLevel (my metadata are ISO 19139-compliant).
I have tried modifying the properties-meanings.xml file, without success.
