Service that manages a project level graph database that records relationships. Most relationships will be stored here, other services can duplicate relationship data if they choose or can use this graph as their source.

As the project grows relationship data can be extended to allow for analysis of relationships, weighting same type connections etc..

== Comparison with RDF ==
 
Property Graph was chosen over RDF because connectivity with external services is not a priority, and can be extracted from a Property Graph. The expected design will have a lot of relationships (predicates) that themselves have properties. Also queries and visualizing the projects objects into a Property Graph seems simpler than using an RDF.
 
= Query language =
 
Focus on using Apache TinkerPop Gremlin for queries as it is the standard used by AWS Neptune for Property Graphs.

Planning all Put/Update/Delete queries to pass through an API/Lambda, however Read/Get queries are able to query the graph directly.
