Today I finally announced the new releases of my extensions on a few wiki mailing lists. I also gave the Semantic Maps documentation another overhaul, and created a manual on how to extend maps.
This manual targets developers who want to add support for a mapping service to one of the features Maps and Semantic Maps support: parser functions, query printers and form inputs. I still have to create the manual for the later two features though. Currently, the subjects of adding a new mapping service, adding parser function support and creating new geocoder classes are covered.
I hope to get the Semantic Maps part done by tomorrow, as a nice conclusion to my GSoC project.
