École française d’Extrême-Orient (EFEO) — Banyan
EFEO’s digital library Banyan was designed and developed by its library and IT services and is explicitly documented as running Omeka S. The institution says Banyan presents its heritage library and archive collections; its digitized documents are published using IIIF standards and stored on Nakala. This records the documented implementation without claiming that the Omeka frontend itself stores preservation files.
