Right, my thinking as well.

No idea what model OGM needs, but I have a hard time seeing project specific meta data
being shared. The information it provides it per definition very specific to the given
project.

That sounds a little over engineered to me. Maybe if I would see some prototype code.
But I am skeptical about this.
