Some fields and how to represent them

location nfo:fileUrl size nfo:fileSize hash nfo:filehash created either fileLastModified on entity and prov:time on wasGeneratedBy transformation prov:activity, prov:wasGeneratedBy id dct:identifier acquired prov:time on wasGeneratedBy with prov:type niprov:acquisition. Only on raw data subject prov:entity + foaf:name parent prov:used project path hostname added transient dimensions protocol code logtext script prov:plan or on the prov:activity args kwargs seriesuid filesInSeries technique repetition-time field-of-view epi-factor diffusion

How to deal with parent files

Use location - > local id cache dict. After provided items have been made into entities, create entities for remaining entries
