State Library of Massachusetts
The State Library of Massachusetts undertook a large migration to escape the limits of flat, single-entity archiving, moving over 750,000 cultural-heritage items from a standard DSpace Express environment to DSpace-GLAM 7. A single-item data model could not properly manage complex museum and archival material, so 4Science restructured the repository into a relational multi-entity model, mapping undifferentiated items into distinct Picture, Archival Material and Audio/Video entities. The migration aligned the collections with international heritage standards while preserving the original organisational logic. A US government-library example of DSpace stretched into rich GLAM description.
