I definitely agree with these points. The policy for a good quality of 
resource descriptions is certainly more important than the repository 
technical solution itself.
Also, our experience with GLU shows us that the resource descriptions 
really used by some institutes for their own functional services are 
generally correctly maintained, other are forgotten and left "as is" in 
the repository. Even with an automatic synchronization system as the GLU 
has, we have this kind of problem, simply the synchronization mechanism 
is applied on out-of-date resource descriptions. And more, as each 
resource cannot be modified or removed by other people than its owner 
(GLU distributed authentification mechanism), we cannot clean ourself 
old resource descriptions without contacting the owner.

As you suggest we should have several synchronized repository centers in 
charge of maintaining a set of resources exactly in the same way that we 
can have moderators on mailing lists, or how Astroweb had been designed 
several years ago. But perhaps not systematically on the institutes 
level as the GLU does presently, but on a more global level (countries 
?) if institutes agree to "delegate" this task.
