I would like to share with you what we have in Murano and start a conversation about metadata repository development in OpenStack. Here is a link to screencast http://www.youtube.com/watch?v=Yi4gC4ZhvPg Here is a link  to a detailed specification of PoC for metadata repository currently implemented in Murano.

Thanks for the link and info. I think the general consensus is this belongs in Glance, however I think details are being deferred until the mid-summit meet up in Washington D.C. (I could be totally wrong about this). In any case, I think I'll also start converting the existing HeatR blueprints to Glance ones. Perhaps it would be a good idea at this point to propose specific blueprints and have further ML discussions focused on specific changes?
