Which role includes end users or other systems who use the results of the Big Data Application Provider?

1. The summary list defines it directly: "Data Consumer: Includes end users or other systems who use the results of the Big Data Application Provider." 2. The phrase or other systems is worth noticing. A Data Consumer need not be a person another system consuming the output counts, which follows from the taxonomy's broad notion of an actor. 3. The Data Provider is the counterpart at the other end of the flow, introducing new data or information feeds into the system. 4. Because one actor can perform multiple roles, the same organisation can be both. The volume's Data as a Service example describes exactly that kind of chain, where transformed data is passed on to a contracted Data Consumer. 5. The System Orchestrator specifies "Data Consumer contracts and SLAs" as part of its business ownership duties, which is a relationship to the role rather than the role itself. _Source: NIST SP 1500-2r2 "NIST Big Data Interoperability Framework: Volume 2, Big Data Taxonomies" (Nov 2019), p.6 section 2.1 "Actors and Roles"_
