Metadata Registry
Dublin Core + Custom Metadata Registry for Archive
The metadata registry is an archival indexing system residing within the Lunar Ark that provides structured author, date, language, format, and provenance records for every stored asset. Drawing 0.5 watts with a 500,000-hour mean time between failures, the component integrates the 15 baseline Dublin Core elements with ISO 19115 geospatial metadata and custom extensions across 30 distinct fields. Lunar archival storage requires a 100-year operational lifetime without external maintenance, demanding versioned, multi-language, and strictly self-describing schemas to ensure unassisted data retrieval and catalog readability by future recovery teams across a century of isolation.
