Allow the user to download data from the record (like a Shapefile, GeoTIFF, etc.) and load directly into the map canvas. See https://github.com/geopython/MetaSearch/wiki/Discovery-workflow for more info.
tl; dr; waiting on CSW with records with links to zipped Shapefile or GeoTIFF for implementation.

I'd like contribute with this functionality.
My idea is to implement the reading of the "missing" protocols (we have a lot in https://github.com/geopython/pycsw/wiki/Geonode-notes) in the library "owslib" or use the library "ftplib" in the plug, as shown in https://docs.python.org/2/library/ftplib.html?
I would also collaborate on access to PostgreSQL / PostGIS.
mainly because, in practice, access through wfs is extremely slow, for large layers (say, all parcels of a city like Rosario, Argentina).
Also, I do not know if there is, I would like to work on a mechanism checkin / checkout layers with concurrent access, and conflict resolution. Obviously, that's for later, but first I want to achieve, at least, to recover a layer efficiently, and have the possibility (which is why I thought ftp), of not having to expose the RDBMS network users.

Note that current efforts around link types can be found in https://github.com/OSGeo/Cat-Interop/blob/master/LinkPropertyLookupTable.csv
I would go about this as follows:
- add "Download Data" button
- look for
startswith('WWW:DOWNLOAD')to activate the "Download Data" button
- at this point clicking the button should take you to a direct link
- of the data. Maybe a generic approach is to open the URL in a web
- browser if the URL is a directory listing (test with something like
if os.path.splitext(urlparse.urlparse('http://example.org/foo.xml').path): # download direct file else: # open in browser
