CC'ing fedora-packaging since there's no need for us to just talk about
these things between ourselves.

There does not need to be a large amount of voice data packages.

I'm mainly wondering what is happening with the db.  If there are
several packages that use the db, then it seems like there needs to be
some coordination among those projects to do so.

It may be.  Usually the Fedora Guidelines are written to tell packagers
how to deal with a standard that originated elsewhere (FHS, .desktop
file handling, etc).

If we're just talking about where on the filesystem the data files shold
be placed and how the packages should be named, then Fedora Guidelines
can cover it immediately (via the FHS and package naming being a
distro-specific standard).  It's the usage of the database that seems a
bit odd to be originating in Fedora rather than some distro-agnostic,
upstream location.

So -- what's the plan for using the db?

Okay.  So the packages that contain voicedata need to Require(XXX):
voicedata where XXX are the scriptlets that update the db.

No problem.  We'll definitely want something written up in the
Guidelines.  I'm just not sure yet what the purpose of all the parts in
the draft is and whether there needs to be cross-distro,
cross-upstream-project consensus to make these effective.
