Very nice idea to measure the quality.
But sorry Tamas, 50% corrupt or 90% corrupt does not make a difference for me.
Especially not, when I have feeling that it is possible to maintain a
100% clean repo with the right automation tools.
If Sonatype's goal is to sell these tools only for paying customers I
don't have a bad feeling about that. Everyone has to make a living.
But I hope sometime similar tools and a clean repo will be available
for the open public.
I hope OSS developers will recognize the need for quality (and a high
quality repo).

Not having a super high quality central repository actually makes our commercial efforts a lot harder. If I was devious I would have agreed with Brett and would make a completely clean central repository as our plans require intact repositories. But we don't have a clean repository and trying to make a separate one would be a disaster for general use. You have to live with what's there and Sonatype will actually invest in cleaning up the generally available repository. We already have with efforts like this:

http://nexus.sonatype.org/oss-repository-hosting.html

It would actually cost us more in support with our clients to maintain a dirty Maven Central and a clean Maven Central with the confusion, interoperability problems and general issues of potential distrust it just makes no business sense. Now the information we want to add is of enormous value but it's predicated on generally improving the quality of Maven Central. I don't want Sonatype to be known as the company that stole Maven Central, doesn't do us any good. So trying to sequester improved metadata somewhere is pointless. If the base information is not good, then the whole system is crippled and that screws Sonatype as well as everyone else.

So the information in Maven Central on a per-project basis I see increasing greatly with some tools that Sonatype is developing in Nexus and M2Eclipse and this will benefit all Maven users generally. I'm certainly going to leverage that improved information, but so can anyone else.

I think we all need some clarification, since we all talk about "quality"

What is the "quality" of a maven repository (in general)? Can we measure
it? Can we define it?

A wiki page with piled up (even personal) opinions would be good --
don't hesitate to start one on MAVENUSER Wiki [1]

whatever they are -- and later we should cherry-pick the most relevant ones to build some tooling to build these metric. And then, we could "measure" the quality of different reposes (like central) and have a list of reposes that do meet certain "level of quality" and list publicly the others that
does not.
