[glue-wg] VOTE by 8/1: GLUE 2.1 for describing cloud resources?

[Salvatore Pinto]

Hi,
please consider that this issue will be only for the Top BDIIs and only 
for the cloud resources. For the site BDIIs, this will hot have this 
issue, since to publish cloud resources they will need to update to 
version 2.1 (and our fedcloud probes will check that), so update of the 
cloud-provider-info script will force update of the glue2-schema.

Regarding the Top-BDII, the problem is also mitigated. In the fedcloud, 
we have two kind of "users": the automatic systems (like AppDB and in 
the future COMPs, SlipStream, etc...), who will install and manage a 
Top-BDII locally, so they will ensure that the Top-BDII is updated when 
they will update their query to use 2.1 (and fall back to 2.0) and the 
"manual users", which uses the Top-BDIIs indicated by the FedCloud, 
reported into a wiki page, which we can easily check if they are updated 
to 2.1 or not.

Cheers,
   Salvatore.

And in any case, it´s still an assumption to think that because a site upgraded the bdii package it also upgraded the glue-schema package. Maybe a fair assumption, but an assumption after all.
