Moreover, it hosts a centralised queue for task requests enabling the tenants to pull new tasks for processing and subsequently post the results. Interactions are possible via a web server interface through the implementation of the HTTP REST API protocol. The backend offers a well-structured relational database, where all incoming requests and results are stored. Alongside the scientific data, details about connected tenants as well as information about the quantities and methods available from the MAP are saved. Further, the database holds information about the data provenance and a history of the status of tenants, methods, quantities, requests and results. Quantities in the sense of the FINALES framework may be measurable quantities, but can also refer to a service like e.g. the transportation of a sample. The term method refers to a means of providing a value for a quantity, which may be an experimental or computational procedure. Since only combinations of quantities and methods are required to be unique in the FINALES setup, this combination is referred to as a capability. Tenants are therefore clients that provide one or more capabilities in the MAP. This means, they regularly call the server for requests related to their associated quantity and, after applying a computational or experimental method, return a result for that quantity. FINALES does not restrict its tenants regarding their source of data or the type of their method. Experimental setups and laboratories run by humans as well as data-driven models or physics-based simulations are accepted as tenants.
