well, i'm aiming at something much lower: namely, how to get the baseUrl of
an OAI PMH data provider? and it seems particularly embarassing, that i have
no standard way to advertise my own service to people (including robots)
surfing my own pages.

stated, but less so on my much smaller one. bekaert says something about the
repository index in lanl's adore architecture. while this is closest to the
problem i'd like to solve, as far as i can see, all attempts for global oai
repository indexes have failed. at least there seems to be no service which
can resolve oai identifiers to repository baseUrls. so i'd be hoping for the
rss way. feed auto-discovery definitely helped a lot to establish feed
aggregators.

did i miss something?
