Figure 7From: SSWAP: A Simple Semantic Web Architecture and Protocol for semantic web servicesResource Response Graph (RRG). The graph returned from the resource to the client with the completed ncbiTaxa:commonName to ncbiTaxa:TaxonomyRecord mapping. In this example the returned sswap:Object is an annotated URI: it is both the URI of the Medicago truncatula web page at NCBI and has semantically well defined predicates with relevant metadata. Elegant models can be built by returning individuals with URIs pointing to data instead of encoding data directly in the graph. Note how the provider's response (RRG) is a variation on the client's invocation (RIG), which is itself a variation on the provider's description (RDG); all graphs are simple variations on the canonical (Figure 2), including the discovery of new resources (RQG).Back to article page
