W3C PROV support¶
We’re using the the W3C PROV data model to capture and represent provenance in Nipype.
For an overview see:
Each interface writes out a provenance.json (currently prov-json) or provenance.rdf (if rdflib is available) file. The workflow engine can also write out a provenance of the workflow if instructed.
This is very much an experimental feature as we continue to refine how exactly the provenance should be stored and how such information can be used for reporting or reconstituting workflows. By default provenance writing is disabled for the 0.9 release, to enable insert the following code at the top of your script:
>>> from nipype import config >>> config.enable_provenance()
