My Entity Instances have properties that are valid for a specific period of time.
In a relational database these would be a timestamp column for a row

- each relationship is associated with a time stamp? (Is this an Edge Property?)
- A grouping of whole graph that basically has all the entities and properties for a time stamp? (Is this a named graph?)
I would like to infer an Instances property values based on a hierarchy of commitment times, such as:
