Entity

A reference to another entity via its ID. This is how entities in FtM become a graph: by pointing at each other using references.

Entity IDs can either be namespaced or plain, depending on the context. When setting properties of this type, you can pass in an entity proxy or dict of the entity, the ID will then be extracted and stored.

Matchable types allow properties to be compared with each other in order to assess entity similarity.

Pivot types are a stronger form of matchable types and can be used to find similar entities based on simple value lookups.
