List of all features you can find in examples/*.json files, but are not mentioned in the spec
- type indexing
- Activity definitions, instead of just Agent and Entities
- Activities attributes defined via key/value list-like pairs, allowing to pass unstructured extra information
- Activities "used" field allow multiple entries : multiple entities as input
- prov:wasInfluencedBy to represent inplace edition of an entity, instead of outputting a new entity (a new "state" of the former entity) and a new Activity corresponding to the edition. This is to encourage human readable representations, as the number of nodes is reduced.
