Table I.3 – Use case – Sharing and aggregating provenance information

Title Sharing and aggregating provenance information

Description Two collaborating BDSPs share provenance information with each other. When BDSP B
uses data from BDSP A:
– BDSP B requests and receives data from BDSP A;
– BDSP B initiating provenance information recoding with storing data from BDSP A;
If BDSP B needs more information (e.g., data history) of received data from
– BDSP A, then requests the provenance information about received data to BDSP A.;
– BDSP B aggregates the delivered provenance information with the local one that was
created when the data from BDSP A was stored.
Roles/sub-roles – BDSP

Pre-conditions BDSP B requested big data to BDSP A and received the data.
(optional)
Post-conditions BDSP B stored the aggregated provenance information.
(optional)
Derived requirement – Searching provenance unit (see clause 8.1);
– Common format for exchange (see clause 8.1);
– Retrieve provenance information (see clause 8.1);
– Simplifying provenance information (see clause 8.4).
