Resource Description Graph (RDG). An example of how the semantic web service taxonomyLookupService describes itself using SSWAP classes and predicates. In this case, the resource maps any sswap:Subject with a ncbiTaxa:commonName to a sswap:Object of type ncbiTaxa:TaxonomyRecord. This is an example of using a database key (a string) to retrieve data. The full Resource Definition Graph (RDG) is at http://sswap.info/examples/resources/taxonomyLookupService/taxonomyLookupService and is available to anyone via a HTTP GET.
