That sounds interesting, but a tad abstract. What kind of content would be converted, and who would write the converters? Or put another way, what would be a good first application to introduce the metadatabase with? Something to do with poses, like the symmetry tool we talked about?

Yes, content that lends itself for conversion are poses, indeed, but also garments, hair and other head-based decorations.

Information for poses support could be which bones need to be adjusted when doing the standard operations like swap left-right, tight to left and left to right, and how to translate split-up upper arms and thighs info like in G8/Nova to the rig arrangement usual in Poser. Rotation angles/quaternions that let the figure take a standard T pose (or whatever the agreed reference pose is), so converters can take the conversion from there.
Yes, all still pretty abstract but that is where it needs to be at at this moment.   

Recent updates to the Python API include CopyMorphFromFigure(). There are still a few rough edges, but once they are solved it means automatic geometry conversion of garments and hair like in the Prefitter-CR2 has become feasible and will likely be on my worklist, along with the autorigging tools. I now use hard-coded figure data. Maintaining figure specific scripts is a nightmare so better have central database.  

Applications and data are like the old chicken-or-egg issue. To resolve the situation one must start somewhere and hope for the best.
