/**
 * We need this module because the TinkerGraph serialized type name is "gremlin:graph" but is likely
 * to change in the next or after DSE version to "tinker:graph" since the change has been done in
 * TinkerPop but we're not sure when DSE will update its TP version. So that way we stay compatible
 * whatever version of DSE is running.
