Actor Definitions

In the Simpl-Open project, various actors play crucial roles in ensuring the efficient operation of our data space. Each actor has specific responsibilities and interacts with the system in its own ways. Understanding these roles is key to grasping the overall functionality of Simpl-Open.
See below all the actors definitions that are included in the business processes.

(Data space) Applicant: An "applicant" refers to an entity that submits an application or request to join, partake in, or receive something from a data space. This term is typically used in contexts where a selection or approval process is in place. Applicants are at the initial stage of engagement with the data space, seeking approval or acceptance which is based on the criteria and procedures set by the Data Space Governance Authority  

(Data space) Consumer: This group includes consumers that can access data, application, and infrastructure from the data space. They can interact with the Simpl in various ways: they can search for data or for other resources, such as algorithms and AI models in the data spaces; use them online by utilizing the infrastructure and services provided by the Simpl Middleware or if policy allows, download them for local usage.

(Data space) Governance Authority: The data space participant that is accountable for creating, developing, operating, maintaining, and enforcing the governance framework for a particular data space, without replacing the role of public enforcement authorities.  

(Data space) Participant: A party that has committed to the governance framework of a particular data space and may have one or more roles in it.

Application Provider: The application providers can be the data spaces or other external systems offering applications via the application catalogue. The term “application” is used in a rather broad sense in this document, and it covers any sort of executables including applications, as well as algorithms, such as a trained AI model that users can leverage to analyse their data. Application providers can also define the access control policies regarding their resources and bill the users for their usage.  

Data Provider: This category covers all the data space actors offering data for the consumers. They can share one or more data sets and regulate the access and usage over the data with the help of access control policies and usage agreements. In order to compensate the data usage, the data providers can also bill the data space consumers. An example of a data provider can be an energy network operator sharing data on the energy grid load towards energy production facilities (who act as consumers) for production optimization application.  

End User: An end user is a real person (human actor) that interacts with the Simpl agent mostly through the UI.

Infrastructure Provider: The infrastructure providers offer infrastructure resources and services to the to the consumers (or possibly to any other type of participant) to enable them to process the data provided by the data providers. They can, for example, launch virtual machines or containers and run applications, algorithms, or other executables on top of the underlying infrastructure. Similarly, to the data providers, the infrastructure providers can define access control policies for the infrastructure resources and bill the middleware users for their usage.  

Representative: A "representative" refers to the human "end user" that takes actions on behalf of an entity actor, such as the: consumer, provider, or governance authority.
