Table I.8 – Use case –Extracting analysis workflow from the
accumulated provenance information

Title Extracting analysis workflow from the accumulated provenance information
Description BDSP A collects the provenance information from the different BDSPs to accumulate the
analysis workflows and reuse them. BDSP C want to find analysis methods that can be applied
to its system functions and data through BDSP A.
Accordingly:
– BDSP A collects provenance information from BDSP B;
– BDSP A extracts the workflows from provenance information;
– BDSP A stores the workflows with an integrated graph which organized by the usage
frequency of the analysis functions and sequential relationship among them;
– BDSP C requests workflow with a list of own functions and data as well as the information
of OS, H/W description, locale settings;
– BDSP A retrieves workflow based on the information came from BDSP C;
– BDSP A sends the list of candidate workflows to BDSP C;
– BDSP C selects the workflow that satisfies the analysis purpose;
– BDSP A reconstructs the workflow in a form that it can run on the BDSP C and send it to
BDSP C;
– BDSP C uses the workflow.
