[openstack-dev] [tc] do we really need project tags in the governance repository?

We can keep the integrated release tag that we have in place now, but we should not adopt any other tags and we should phase out the tag system when we drop the integrated release tag.

The TC should be responsible for evaluating teams and projects that want
to join OpenStack. If we use tags for that purpose, then we should vote
on them. We don't seem to be using tags for that purpose, though (at
least not after we drop the incubated release tag).

themselves not sufficiently useful for evaluating projects. If someone
wants to choose between Ceilometer, Monasca, or StackTach, we're
unlikely to come up with tags that will let them do that. They need
in-depth discussions of deployment options, performance characteristics,
and feature trade-offs.

As someone new to the project, I would not think to look in the
governance documents for "state" information about a project. I would
search for things like "install guide openstack" or "component list
openstack" and expect to find them in the documentation. So I think
putting the information in those (or similar) places will actually make
it easier to find for someone that hasn't been involved in the
discussion of tags and the governance repository.
If we need a component list with descriptions, let's build that. It can
be managed by a team of interested parties -- perhaps some of the
operators or deployers, for example. I don't know if we have an existing
place where it would make sense to put it, or if we need a new
repository. We've been applying DRY to the existing projects/programs
list and saying that because we already have a list in the governance
repository we shouldn't repeat that information elsewhere, but we're
also starting to go to a lot of lengths to define a format to hold
information (tags, with metadata, a taxonomy, etc.) that isn't needed
for project governance. That makes me think we're trying to force-fit
this idea into a single list.

I agree that a product matrix with some basic information will be useful
for deployers and operators to find project details, which can then go
into more depth about the issues operators and other downstream users
care about. I just don't think the TC needs to host or maintain that
When we talk about things going into the governance repository, we
should apply two rules. First, we should consider whether it is
*appropriate* for the TC to be making decisions about the topic.
Subjective tags fail this test. Second, we should consider whether it is
*necessary* for the TC to be making the decision. Objective tags fail
