University of Edinburgh
The University of Edinburgh built a comprehensive Digital Archive service on a strictly open-source, modular architecture. Enforcing a 'golden copy' standard, Archivematica analyses bit-level fixity and generates standards-based preservation packages, which are managed through a preservation registry ('Archipelago'), while ArchivesSpace handles archival description. The deliberately decoupled design lets the library treat preservation and access as separate, swappable layers rather than a single monolithic system — a mature UK example of assembling a digital-preservation ecosystem entirely from open-source components under a clear golden-copy policy.
