I thought the analysis on service catalogs might attract some attention. ;)

AFAICT it’s arbitrary. Provider picks the string used in the service type.

However in devstack, zaqar is listed as “messaging”. FWIW i think the rackspace entry came before the devstack entry, but there is now an inconsistency.

That’s what we’re hoping to achieve with guidelines around the service catalog. So when the provider goes to pick the strings used in the service catalog, there’s consistency.

Yes. This is what would be part of the guideline.

To date, this has been the case. The DevStack version of the service catalog sort of became a de facto standard. But not de facto enough and hence the inconsistency.
It’d be great to hear thoughts from Adam Y, Dolph M, and Dean T on the subject. I don’t think I have the full picture.
