OCR demo files: Food for Space Flight

Files for trying OCR on NASA's Food for Space Flight booklet. The matching dataset contains seven page images with source-page metadata.

Path	Contents
original/food-for-space-flight.pdf	The unmodified nine-page NASA PDF.
demo/food-for-space-flight.pdf	PDF pages 3-9, matching the seven dataset rows.
pages/	The same seven page images and metadata.

Use one prefix as your input: hf://buckets/uv-scripts/ocr-demo/demo for the seven-page PDF, /original for the complete document, or /pages for images. Pointing a recursive OCR recipe at the Bucket root would process the same pages in multiple formats.

NASA's document record states Work of the US Gov. Public Use Permitted. The source pages retain that status; the repository's code licence does not relicense the document. Attribute the source pages to NASA. NASA does not endorse this demo or verify any generated OCR output.

Pages 3-9 (printed pages 2-8) were rendered at 300 DPI and saved as JPEG at quality 85. manifest.json records the source URLs, file sizes and SHA-256 checksums. The archival scan has damaged lettering and an imperfect existing OCR layer; this is demo input, with no verified ground-truth transcription.
