Supervision of the amount and type of data flowing through the Middleware; and what it is being used for https://confluence.simplprogramme.eu/display/SIMPL/Data+Usage Data Usage Direct access to the dataset In this scenario, the data is shared directly between the provider and the consumer (outside of Simpl-Open) and as such no usage policy can be enforced (only "legal enforcement" possible). It corresponds to the "allow usage of data" and "use data and delete afterwards" policies. This also implies that billing always happens as a one-time payment, upfront of the consumption (possible extension to BP 07). There is thus nothing that Simpl-Open agent can log or monitor during consumption. Data is accessible from an infrastructure tenant In this scenario, the data provider shared the data on an infrastructure tenant provisioned by an infrastructure provider. 2 types of usage policy are considered, which can be technically enforced and billed: Based on number of usages (e.g. access the data 3 times) Based on duration (e.g. access the data for 7 days) In both cases, policy enforcement and billing can be performed based on the logs from the storage.
