+=====================================
+Building with a chosen graph database
+=====================================
+
+
+
+The Atlas build is currently set up to include one of the graph backends in the Atlas war file.
+The choice of graph backend is determined by the setting of the GRAPH-PROVIDER system variable.
+
+If GRAPH-PROVIDER is not set, the default graph backend is adopted. This is currently Titan 0.5.4.
+
+In order to build with a specific (non-default) graph backend set the GRAPH-PROVDER system variable.
+
+If GRAPH-PROVIDER is set to titan0, the build will contain Titan 0.5.4 (i.e. the default above)
+If GRAPH-PROVIDER is set to titan1, the build will contain Titan 1.0.0
+If GRAPH-PROVIDER is set to janus, the build will contain JanusGraph 0.1.1
+
+For example, to build Atlas with the janus graph-provider:
+mvn install [-P dist] -DGRAPH-PROVIDER=janus
+
+
+Titan 0.5.4 supports Gremlin2 only, whereas Titan 1.0.0 and JanusGraph support Gremlin3 only (and NOT Gremlin2).
+Gremlin2 and Gremlin3 are not compatible. The gremlin used by Atlas is translated into either Gremlin2 or
+Gremlin3 depending on which graph backend is used in the build. This is implemented in GremlinExpressionFactory.
+
+
+REQUIREMENTS
+------------
+
+Titan 1.0.0 and JanusGraph 0.1.1 require Java 8 to be used both when building and running Atlas.
+Unless Java 8 is used, the janus module will not be built - this is checked by the maven-enforcer-plugin.

-/**
- * Abstract implementation of AtlasGraphQuery that is used by both Titan 0.5.4
- * and Titan 1.0.0.
- * <p>
- * Represents a graph query as an OrConditions which consists of
- * 1 or more AndConditions. The query is executed by converting
- * the AndConditions to native GraphQuery instances that can be executed
- * directly against Titan. The overall result is obtained by unioning together
- * the results from those individual GraphQueries.
- * <p>
- * Here is a pictoral view of what is going on here. Conceptually,
- * the query being executed can be though of as the where clause
- * in a query
- *

+==================
+JanusGraph README
+==================
+
+IMPORTANT: Support for JanusGraph in Atlas is currently a work in progress.
+
+
+ARCHITECTURE NOTES
+------------------
+
+To build Atlas with JanusGraph, you must set GRAPH-PROVIDER as follows:
+
+mvn install [-P dist] -DGRAPH-PROVIDER=janus
+
+
+JanusGraph support Gremlin3 only (and NOT Gremlin2), so the gremlin used by Atlas is translated into Gremlin3
+by the GremlinExpressionFactory.
+
+
+
+REQUIREMENTS
+--------------
+
+JanusGraph requires Java 8 to be used both when building and running Atlas.
+Unless Java 8 is used, the janus module will not be built - this is checked by the maven-enforcer-plugin.
+
+
+USING ATLAS WITH JANUS GRAPH
+----------------------------
+
+1) Build Atlas with the janus graph-provider maven profile enabled:
+
+mvn install [-P dist] -DGRAPH-PROVIDER=janus
+
+Some tests in the repository and webapp projects are skipped when running with the janus provider, due to hard
+dependencies on Gremlin2. These components need to be updated. Please refer to "known issues" section below.
+
+This will build Atlas and run all of the tests against Janus. Such a build MUST be used with JanusGraph and
+CANNOT be used with any other graph provider, e.g. Titan 0.5.4 or Titan 1.0.0.
+
+2) Configure the Atlas runtime to use JanusGraph by setting the atlas.graphdb.backend property in
+ATLAS_HOME/conf/atlas-application.properties, as follows:
+
+atlas.graphdb.backend=org.apache.atlas.repository.graphdb.janus.AtlasJanusGraphDatabase
+
+3) Attempt to start the Atlas server.
+
+
+KNOWN ISSUES
+------------
+
+None yet...
