Hi
MapFish's python package [1] basically provides the following:
1- a paster_create_template entry point [2] for creating MapFish
applications with "paster create -t mapfish". MapFish applications are
basically Pylons applications with an extra command (paster mf-layer)
for creating RESTful web services relying on PostGIS tables
2- a Geometry sqlalchemy.types.TypeEngine [3]
# example:
table = Table('postgis_table_name', metadata,
Column('gid', Integer, primary_key=True),
Column('the_geom', Geometry(4326))
)
Geometries read from PostGIS are converted into Shapely [4] geometries.
3- the implementation of the MapFish RESTful protocol for reading,
creating, updating and deleting geographic objects [5]
We're interested in feedback and collaboration on that.Thanks!
