Have done some more work on the annotations demo at
As well as adding an annotation (in 'Annotate' mode), the OpenLayers tile
engine now fetches annotations from the server and displays them as markers
on the map; you can find out details on the annotation by clicking on it.
The annotations are sent back from the server in a simple XML format, inspired
by GeoRSS; I am not using GeoRSS itself as apparently it is not designed to
be used with tiles and bounding boxes. You can get an idea of the format by
entering this URL:
I started developing this originally with free-map.org.uk in mind; however it
could also form the basis for an OSM annotations layer. Does anyone
(particularly Steve) have any comments/feedback on this? Or
suggestions/modifications for OSM?
