Interface IRemoteRepository

public interface IRemoteRepository

Interface for the Java API to the NanoSparqlServer. See for more information on the HTTP API. The instance will be constructed with the endpoint URL for the NSS and the namespace for the kb. It will then issue a query to learn some basic metadata about the database (e.g. what mode it's in).
