| Step | Command‑line Tool | Example Command | What It Checks | |------|-------------------|----------------|----------------| | | file (Linux/macOS) or exiftool | file *.tif | Confirms actual format vs extension. | | Resolution & bit‑depth | identify (ImageMagick) | identify -format "%[resolution.x]x%[resolution.y] %z\n" *.tif | Returns DPI and bit depth. | | Checksum | sha256sum or openssl dgst -sha256 | sha256sum *.tif > checksums.sha256 | Generates a hash for later verification. | | Metadata audit | exiftool | exiftool -XMP:Creator -XMP:Rights -XMP:Language *.tif | Extracts required XMP fields. | | Colour‑space & compression | exiftool / identify | identify -verbose *.tif \| grep -i "Colorspace" | Verifies sRGB/AdobeRGB; also checks compression tag. | | Orientation | exiftool -Orientation | exiftool -Orientation *.tif | Ensures value = 1 (Normal). | | Naming pattern | grep or custom script | ls *.tif | grep -P '^Kamakatha\d3_\d3\.tif$' | Enforces naming rules. |
| Reason | Impact on the Collection | |--------|---------------------------| | | Certain formats (e.g., TIFF, JPEG‑2000) are better suited for long‑term archival because they are open, well‑documented, and widely supported. | | Searchability & OCR Accuracy | High‑resolution, loss‑less images preserve the fine details of Tamil script, making Optical Character Recognition (OCR) and subsequent text‑search far more reliable. | | Interoperability | Uniform format choices simplify sharing with partners (e.g., other libraries, cultural institutions, or crowdsourcing platforms). | | Legal & Copyright Compliance | Provenance metadata embedded in image files can help demonstrate that the digitisation was done under a lawful framework. | | User Experience | Web‑ready formats (JPEG, WebP, AVIF) enable fast loading on mobile devices while still presenting the delicate calligraphic nuances of the script. | | Automation | Consistent file‑type and naming conventions allow scripts and pipelines (e.g., for batch OCR, metadata extraction, or AI‑based style analysis) to run without manual intervention. | tamil kamakathaikal images format verified
