SPARQL becoming more and more powerful in the new GC (available with >= CLM 6.0).

The Question that will come is “How could I use SPARQL and GC from Javascript?” Before we continue with Javascript it is always a good practise to start with the Advanced REST Client of Chrome.

Lets refresh our skills with a basic example of a SPARQL Query “Get all Software Requirements in a dedicated DNG Project Area”

Let us now discover the possibilities of SPARQL Queries with GC…

1. Use the SPARQL Endpoint https://<LQE Host>:9443/lqe/sparql-variable-config and a header with “Configuration-Context”

1. Use the SPARQL Endpoint https://<LQE Host>:9443/lqe/sparql-variable-config with a query parameter like “?oslc_config.context=…”
2. Use the SPARQL Endpoint https://<LQE Host>:9443/lqe/sparql and GC inside the SPARQL Query

Open points: SPARQL Query against “unversioned Data” SPARQL Endpoint like https://<LQE Host>:9443/lqe/sparql-unversioned
