QGIS » QGIS Application

Hi
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)[1]:
    # download direct file
else:
    # open in browser
