13. The method of claim 11 , where generating a selection term declaration event comprises generating an event containing data which, when applied to the relational database via the output query, identifies RDF triples including a specified term.
11. The method of claim 1 wherein the first query is schema-less in a first language and the second query is an output query in a second language, the method further comprising: performing, by the computer system programmed with code stored in the memory and executing by the processor of the computer system that further transforms the computer system: generating the second query comprising: examining the schema-less first query in the first language for the one or more tokens; dispatching the context-specific grammar events to be used in generating the second query, populating portions of the second query according to at least the context-specific grammar events; and extracting data, represented by the tokens and contained within the context-specific grammar events, from the context-specific grammar events to generate the second query in the second language, comprising the populated portions, wherein the second query represents a schema of a relational database storing RDF triples; wherein each of the events represents any of a declaration and a constraint specified in the first query, and wherein the constraint specifies RDF triples to be identified.
