Hi I am interested in extending mapstraction to include the UK Ordnance Survey OpenSpace API (http://openspace.ordnancesurvey.co.uk). First can I check that no-one else is working on this? Assuming not, is there any documentation that might point me in the right direction to get started, or should I just search the code for case ''google'' and insert appropriate code at each point?
