> *Terminology*
> Id: And identifier interface.  The identifier has a string type, and a UUID
> Edge Type: The type of the edge as a string.  "like", "follows" etc
> Version: A time uuid that represents the version of the edge between the source and target
> Source: The source node in the directed edge
> Target: The target node in the directed edge.
> *Data access operations*
> Get edges from source by edge type
> Get edges from source by edge type and target type
> Get edges to target by edge type
> Get edges to target by edge type and source type
> Get all edge types from source
> Get all target types from source with edge type
> Get all edge types to target
> Get all source types to target with edge type
