I have a local installation of GeoNetwork 3.10.4 where I want to add a metadata schema that is available on Github. The schema can be found here: https://github.com/geoadmin/geocat/tree/geocat_3.4.x/schemas - I want to add the schema
I tried to copy the folder with its contents to the directory
web\geonetwork\WEB-INF\data\config\schema_plugins but the new schema does not show up in the metadata and template section after I restart the application.
Also, I read that it should be possible to upload a ZIP-file with a new schema, but I don't see any place where I can upload a schema in the GeoNetwork admin section.
How could this particular (or any schema) be integrated to another GeoNetwork installation?
