metadata management tools

[Liam Hoekenga]

We're looking at bringing up a campus federation to allow UMich only 
resources to start leveraging shibboleth.

We've found an SP self registration tool published by UW that seems like 
it could fit nicely into our plan.  It's the "Service Provider registry 
web service", available from..

     http://staff.washington.edu/fox/shibboleth/

..but that's really strictly for SP management.  We're looking for 
something to help take this SP-only metadata file and wrap with the "rest" 
of the rest of the federation metadata (IdP information, certificates, 
expiration, etc).

It seems like, eventually, the Metadata Aggregator project may be able to 
do this for us..

What are people using now to manage their local federations?  Are there 
existing tools to create federation metadata that anyone's willing to 
share?
