Annotea protocol was written to support the user browsing through the 
annotations and rather having some information sooner than all the 
information too late. The Algae queries supported wider range of 
queries. I think now we could start using SPARQL for that.

If many people need this we can also discuss about updates to the 
protocol. I remember that IBM SemTag project had an extension to get 
more information at one request.
