based on zgeo.geographer andzgeo.plone.geographerprovides the basic mechanism toenter geographic data intogeoreferenceable contents
any object can be georeferenced
>>> class Placemark(object): ... implements( ... IGeoreferenceable, ... IAttributeAnnotatable ... )
>>> placemark = Placemark()
>>> geo = IGeoreferenced(placemark) >>> geo.setGeoInterface('Point', ... (-105.08, 40.59))
