Provenance

The package stores the provenance records i.e.:

• which input files were used,
• which processes or scripts were executed,
• what parameters, software versions, and container images were used,
• what outputs each step produced, etc.

While using nextflow, provenance reports of the workflow executions are rendered using nf-prov plugin. In the case of snakemake, Metadata4ing reporter is used. The provenance report is stored in RO-Crate format.

Terminologies

Parameter Extractor

parameter_extractor.py passes arguments to the metadata4ing reporter plugin. It parses the parameter configuration files and their corresponding output files.

Metrics Plotting

plot_metrics.pycontains implementation for:

• Reading the RO-Crate files using rdflib.
• Running a SPARQL query on the rdflib graph objects.
• Plotting the simulation outputs tool-wise from different parameter configuration runs.
