A gist to detect whether the group of records has an editor key, if the editor key exists, if the editor key doesn't exist for that particular group we add it (because this should have one), and adds this editor if we have nothing.

addMissingEditors.py

import glob, json

files = glob.glob("*.jsonld")
for fileName in files:
  with open(fileName, "r") as record:
    recorddata = json.loads(record.read())
    if recorddata.has_key("hydra:hasEditorGroup"):
      if recorddata[u"hydra:hasEditorGroup"] == {u'@id': u'und:[redacted]'}:
        print 'true'
      else:
        recorddata[u"hydra:hasEditorGroup"] = {u'@id': u'und:[redacted]'}
        newfile = "new-" + fileName
        with open(newfile, "w") as outfile:
          json.dump(recorddata, outfile, sort_keys=True, indent=4)
    else:
      recorddata[u"hydra:hasEditorGroup"] = {u'@id': u'und:[redacted]'}
      newfile = "new-" + fileName
      with open(newfile, "w") as outfile:
        json.dump(recorddata, outfile, sort_keys=True, indent=4)
