MapFish 2.2 is the current release
MapFish extends the Pylons web framework with tools (commands) for creating web-mapping projects, and web services for querying and editing geographic objects.
Web-mapping application developers working with MapFish use GeoAlchemy for reading/writing geographic objects from/to spatial databases, Shapely for manipulating geometries, ExtjS, GeoExt and OpenLayers for creating UIs. They also have all the libraries of the Pylons ecosystem at their disposal, these libraries include - but aren't limited to - the SQLAlchemy database toolkit, the Mako template engine, the repoze.who and repoze.what security frameworks.
With MapFish, web-mapping application developers combine general-purpose web technologies with geospatial-oriented libraries in their applications; for example, this makes it possible to leverage general-purpose web security frameworks to secure geographic feature web services.
This makes MapFish a framework of choice for building custom GIS applications for the web.
