Verdict
A disk-native photo cataloguer and batch editor sold as a one-off perpetual licence, for photographers with large libraries who don't need Lightroom/Capture One-level RAW editing.
An on-prem, cloud or hybrid DAM aimed at likely DACH-region enterprise manufacturers who need to keep data in-house, with a public review record too thin to lean on without running your own trial.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
An open-source DAM, CMS, and PIM platform combining asset, content, and product management for mid-to-large enterprises in banking, insurance, and retail.

Quoted per customer
No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
Cloud service: billed by storage capacity (GB) plus which optional modules you select; user accounts are unlimited/uncapped. No public price list — pricing is obtained via a configurator/calculator or by requesting a quote. On-premise/hosted deployments use Free, Standard, and Enterprise license editions (feature-gated), also quote-only. A non-commercial Free Edition exists with no disclosed price.
