Blazegraph accepts user-supplied IDs (strings only) for vertices and edges. If no id is supplied a UUID will be generated. By default, TP3 ids and property keys are converted into URIs by prepending a <blaze:> namespace prefix. Property values are simply converted into datatyped literals.

Two fixed URIs are used and provided by the BlazeValueFactory to represent element labels (rdfs:label by default) and property values for Cardinality.list vertex properties (rdf:value by default). These can also be overriden as desired.

## Getting up and running with Blazegraph/TP3

Currently **BlazeGraphEmbedded** is the only concrete implementation of the Blazegraph Tinkerpop3 API. BlazeGraphEmbedded is backed by an embedded (same JVM) instance of Blazegraph. This puts the enterprise features of Blazegraph (high-availability, scale-out, etc.) out of reach for the 1.0 version of the TP3 integration, since those features are accessed via Blazegraph's client/server API. A TP3 integration with the client/server version of Blazegraph is reserved for a future blazegraph-tinkerpop release.
