Adding Structural Metadata to Locally Digitized Content in HathiTrust (2) Using PageTag software, structural metadata is added to a relational database to drive the HathiTrust pageturner interface. Options include title pages, chapters, page numbers, indices, and other sections. (4) Using a combination of Perl and shell scripts, the database outputs a text file with structural metadata and OCR confidence ratings. This is combined with the original page images for HathiTrust ingest. (3) The page images undergo OCR processing with PrimeOCR software. (5) After ingest, the images and metadata come together in the HathiTrust pageturner. Jason Colman & Kathryn Horne University of Michigan Library (1) The process accepts three standard digitization formats: PDF, JPEG2000, & TIFF.
