  Resource Description Framework (RDF) and Property Graph (PG) are the two most
commonly used data models for representing, storing, and querying graph data.
We present Expressive Reasoning Graph Store (ERGS) -- a graph store built on
top of JanusGraph (a Property Graph store) that also allows storing and
querying of RDF datasets. First, we describe how RDF data can be translated
into a Property Graph representation and then describe a query translation
module that converts SPARQL queries into a series of Gremlin traversals. The
converters and translators thus developed can allow any Apache Tinkerpop
compliant graph database to store and query RDF datasets. We demonstrate the
effectiveness of our proposed approach using JanusGraph as the base Property
Graph store and compare its performance with standard RDF systems.
