Fig. 2: Scope provenance.
From: Common workflows for computing material properties using different quantum engines
a Schematic provenance of a workflow (PA) that takes two inputs (I1 and I2) and produces three outputs (O1, O2, O3). b A more detailed view of the complete provenance of PA, which actually runs two subprocesses (SA and SB). Input I1 is passed by PA to SA, which results in O1. This intermediate output O1 is passed by PA to SB as an input, in addition to I2, which results in the outputs O2 and O3. The latter are returned by PA as the final outputs together with the O1 intermediate result.
