Open Stack

Hi,

We had a discussion yesterday on the Heat channel regarding patterns for searching or filtering entities by its metadata values. This is in relation to a feature that is currently being implemented in Heat called “Stack Tags”.

The idea is that Heat stack lists can be filtered by these tags, so for example, any stacks that you don’t want to see you can tag as “hidden”, then when you request a stack list you can specify that you only want stacks that do not have the “hidden” tag.

We were trying to find other similar usages of tags and/or metadata within OpenStack projects, where these are not only stored as data, but are also used in database queries for filtering. A quick search revealed nothing, which is surprising.

Is there anything I may have missed? I would like to know if there anything even remotely similar, so that we don’t build a new wheel if one already exists for this.

Thanks,

Miguel
