Create game map with Blender I'm developing an web-based 3d RPG game using HTML5 technology stack. 
I'm trying to use Blender as much as it possible in my project. I'm using it to create models, landscape meshes, to draw blend maps for landscape textures and so on. Now I'm thinking about how can I use blender to make maps. I can't just put objects and export whole scene. I will have some objects repeated many times over level so I just need information about objects coordinates, rotation, scaling and some custom properties  (like class name from my framework).

So my question is - what options do I have to make this with Blender?
Currently all I can think of is to write a custom plugin for blender to export map in wanted format.
In the obj exporter there is the option


  Objects as OBJ groups


If this is checked it will maintain separate objects in the scene as well as their transforms in world space.
