This follows on the plea I made to think about services on top of Semantic Web / Linked Data resources. Carole called them 'top-middleware' services I think.

Would this make sense?

  -> exposes content via Generic Semantic Web interface (Sesame API?, - we have Web Service available for that.) [Note from Juande: Sesame is a web service for giving back information on astronomical object names, what's this Sesame?]
  -> RO-services expose RO specific interface for (web) applications (SOAP service, Ruby gem, etcetera?)
  -> Various web applications can perform RO-specific I/O through an application-specific user interface (typically not made by us)
