The Virtual Map Forum 2.0 allows the searching and viewing of historic and georeferenced maps and offers further capabilities for the georeferencing of historic maps. The vk2-georeference is therefor the backend systems, which allows the production of temporary georeference results by offering a web service and the production of persistence georeference results by running a daemon in background. Client code which works with the vk2-georeference web service could be found in the vk2-extension project.
