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
