Transformer datadate

When a transformer runs, transcript.exe is executed and one of the command line arguments it requires is a date in yyyyMMdd format which is termed the data date. The activities performed by Transcript are associated with this date in several ways, most notably:
  • when importing using automatic source tagging which specific Dataset file to import from \collected
  • to determine the concept of 'today' when processing files containing data with timestamps spanning multiple days
  • to determine the output directory into which RDF files will be generated
  • to generate the filename of the RDF files generated
The data date is made available to a Transcript task through the automatic creation of the ${dataDate} variable
