Add OCR text files to DIP

  • Add open-source OCR tool to Archivematica
    • Tesseract is the most actively developed; other open-source OCR is either moribund (Cuneiform, OCRopus) or released only sporadically without major improvements (OCRad, gOCR).
    • The actively-developed options are:
      • Tesseract - Very actively developed. Best accuracy of all the open-source options, good speed.
      • OCRad - Moderate-to-poor accuracy, excellent speed.
      • gOCR - Poor accuracy, slow speed.
    • Tesseract appears to be the best solution in most cases. If speed was paramount and mediocre or poor accuracy would be acceptable, there might be an argument to use OCRad.
  • Add micro-service to OCR files in DIP (post-normalization)
    • Micro-service: OCR files
    • User choice Yes/No
  • Add OCR files to DIP in "[DIP]/OCR files" directory
  • Add OCR files to AIP in "[AIP]/data/objects/submissionDocumentation"
  • Add configuration setting to administrative tab of the dashboard to pre-select OCR options
