The SPARQLServiceResolver is used to manage a set of FederatedService instances, which are used to evaluate SERVICE expressions for particular service Urls.

Lookup can be done via the serviceUrl using the method AbstractFederatedServiceResolver.getService(String). If there is no service for the specified url, a SPARQLFederatedService is created and registered for future use.
