Mapnik provides a server package to allow the publishing of maps

The ogcserver obviously needs layers to publish. For now, with Mapnik, this
can only be done by writing code. In this case, a Python script will need to be
written to describe the layers and respective styles. For information on the Python
API, look in demo/python, or in docs/epydocs.
The server needs a python module, with code that looks like this:

- For human readable info, set the title and abstract properties on the layer
object.
- DO NOT register styles using layer.styles.append(), instead, provide style
information to the register_layer() call:
information to the register_layer() call::
register_layer(layerobject, defaultstylename, tuple of alternative style names)
register_layer(layerobject, defaultstylename, tuple of alternative style names)
- No Map() object is used or needed here.
- Be sure to call self.finalize() once you've registered everything! This will
validate everything and let you know if there's problems.
- For a layer to be queryable via GetFeatureInfo, simply set the 'queryable'
property to True:

This is the very first implementation of a WMS for Mapnik. Although inital
testing seems to suggest it works well, there may be bugs, and it lacks some
useful features. Comments, contributions, and requests for help should all be
directed to the Mapnik mailing list.
