Before revision:  This allows to access and query a wide variety of Graph Data Management Systems ( DMSs ) using the W3C standardized SPARQL  and avoid the steep learning curve of a new Graph Query Language (GQL) . Gremlin is a graph computing system agnostic traversal language ( covering both OLTP graph database or OLAP graph processors ), making it a desirable choice for supporting interoperability for querying Graph DMSs.
