Hi Raphaël and everybody,

let me make a couple of short clarifications about debian/upstream.

 - We use it in Debian Med, and there is currently no replacement availalbe.

 - If a superior solution emerges, I am happy to use it, and I am sure
   that it will be the case of the other Debian Med members.

 - Monitoring the package's VCS is a key feature: it gives ACLs for free, and
   removes the need for uploading source packages.  For Debian Med, all Debian
   developers have write access to our VCS.  I would be happy to extend this to
   all Alioth users, but it has been discouraged in the past.

 - The file is also present in source packages, but we do not rely on it to be
   there.  I have not read any convincing argument that it is an abuse. I see
   it more like a backup as a side effect. Each source distribution of Debian
   comes with a full copy of its "Upstream Metadata".

 - The DEP is a draft, about fixing the syntax of debian/upstream.  It is not a
   proposition about an implementation, because it is already implemented.  How
   the data is further propagated is also out of the scope of this DEP.  (Which
   does not mean that it is not important or that it should not be discussed,
   of course).

 - The debian/upstream data is aggregated and refresehd using "Umegaya", running
   on upstream-metadata.debian.net.  It is commited in a file pool in Debian QA's
   "collab" subversion repository, and some of the data is sent to the UDD.
   You can find more details at the followign URL:


 - (To Olivier): it does not use RDF because we do not have an easy way to let
   package maintainers to declare metadata without having to learn and control
   the syntax of RDF (or Turtle, etc), which I find heavy and difficult.  But
   it is in the scope of DEP 12 to make a one-to-one relationship between fields
   of debian/upstream and other ontologies, so that the PTS or other engines
   could serve the data in a semantic-friendly format.

In conclusion, if this year's SoC produces a PTS that makes it easier to
register arbitrary metadata (and I insist on arbitrary extensibility to give
the possibility to experiment), I have no problem to migrate from the
debian/upstream concept, but in the meantime, let's avoid "chilling effects" of
better solutions awaiting for an implementation.
Have a nice bon week-end !
