GNIP 16 - Remote Services

Overview

It is proposed to add functionality to GeoNode that allows users to configure external OGC services (WMS/WFS/WCS/CSW primarily) to be included in a GeoNode site. The various ways that an external service/layer could be configured has been discussed on the geonode list (see here https://groups.google.com/a/opengeo.org/group/geonode-dev/browse_thread/thread/7815b2b724ec4d94/cf33c41672230a36?lnk=gst&q=federation#cf33c41672230a36).

Motivation

Currently it is possible to add an external WMS layer to a map in GeoNode by entering the URL to the service in the Add Layer Dialog in the Map Composer, but it is not possible to add an external service such that the external layers have their own GeoNode Layer pages and the features that come along with that. Many GeoNode users have asked about 'federation' functionality which would allow them to associate other GeoNodes with the site they are working on. Adding functionality for these types of external services is the first step toward accomplishing that goal.

Proposal

It is proposed to add a new Service class to geonode.maps.models that will contain fields necessary to identify and store metadata for remote WMS, WFS, WCS and CSW services, and to develop the views necessary to allow these services to be configured. It is also likely that changes will be required in both gsconfig.py and also potentially in GeoServer to accomodate these features.

Issues

TODO: MANY!

Testing

Extensive Integration tests will be required to validate this new set of features.

Alternatives

Do nothing. GeoNode does not currently provide this kind of functionality.
