5. Actors

Actors are the people, organizations, and external systems that interact with the system. They are described by the roles they play.

There are many other Actors in addition to the ones described here. We have focused initially on the Actors that illustrate key near-term capabilities of the system.

Data Originator

A Data Originator makes science data or metadata available to the community. Typically this person is a data manager, acting on behalf of a scientist that arranged for measurements to be made, post-processing to be executed, or models to be run. (In this document we consider model outputs to be data.) However, the level of expertise of the Data Originator can vary widely.

Data User

The Data User wants to discover and use science information, such as that provided by the Data Originator. The Data User is often a scientist, but may also be an educator, policy maker, or system operator.

Solution Developer

A Solution Developer creates systems (that consist of, or at least include, software) for managing data. The key characteristic of the role with respect to this document is its ability to create applications or services that interact with the semantic framework.

Information Architect

The Information Architect wants to understand the relationships between different information models or semantic models, or wants to design an information or semantic system that supports the desired semantic functions. One particularly applicable example is creating a community vocabulary that is maintainable and has other desirable qualities for its users.

Device Manufacturer

The Device Manufacturer produces a system with complex capabilities, and (for the purposes of this document) wants that system to gracefully interoperate with observing systems (and their associated semantic frameworks). One task that the Device Manufacturer must perform in order to produce interoperable devices is provide data describing their sensors, using terms from described vocabularies.
