I am a newbie on openstreetmap related developments, I need to build a web application using PHP or Python frameworks, that could draw map using OSM data. It should also allows to edit attributes of nodes (ex: highway, signal lights, foot path, parking etc), edited data should not need to be updated to OSM servers.
I couldn't find any proper guide. Let me know if there any guides or tutorials to do so.
Where should I start?
