GRAPH API: DEFINITION
“A RESTful, user-centric, hypermedia API that organizes web
resources under a unified meta-model of Objects, Aggregations of
objects and Connections towards them which are created by users.
It is based on a common dictionary and it includes a minimum set of
properties in order to reduce time and cost of connection and
integration with other APIs.”
