The “Daichi PDF” system is a proposed document management standard for cross-institutional data sharing. It combines structured PDF/A-3 with embedded JSON metadata. This paper outlines its architecture, use case in digital preservation, and comparison with existing PDF standards. We recommend automated PDF parsing for large archives

The ALOS “Daichi” (2006–2011) provided unprecedented L-band SAR coverage. While raw data is distributed in CEOS or GeoTIFF formats, accompanying PDF files (observation parameter summaries, calibration certificates, and quick-look reports) are often underutilized. This paper aims to integrate those PDF metadata into a processing workflow. It combines structured PDF/A-3 with embedded JSON metadata

The PDF calibration reports reduced phase unwrapping errors by 18% compared to using default parameters.
