Conceptual architecture

Overview

The diagram below shows the high level functional blocks needed for a registry service implementation. This is not a formal component architecture in that there is no requirement for the internal component structure to be divided into precisely these blocks. The only formal component interfaces are the external interfaces defined in the Api specification which in turn reference open standard specifications, particularly SPARQL 1.1.
