I had written a Blender script to export data about objects in the scene: https://jhocking.itch.io/dropper-for-blender
Essentially it's a simple level editor. It writes out JSON or XML with the names, positions, etc.
As the description explains, I had first written a Blender script to do this years ago, but Blender's API changed soon after and that script no longer works. Ever since I've been meaning to re-write the script in the new API, and this toolbox jam finally gave me a reason to do it!
