Billed on
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.
No genuine dollar pricing is published. The vendor's package-comparison page lists four tiers: Community Edition (free, open-source, self-hosted), Growth (SaaS, shown only as "Starting at $0 Annually" with a free-trial CTA — no real recurring price disclosed), Advanced and Premium (both "Call for a quote"). No billing unit (per user, per SKU, per asset, per GB) is stated anywhere on the site for the paid tiers.
No public price list; sales quote required for both packages (Prime and Ultimate). Adobe's own on-premise product description sheet lists separate license metrics per component — AEM Assets itself is licensed 'Per Instance', 'Users' are licensed 'Per User', Brand Portal is licensed 'Per Brand Portal User', and Dynamic Media/Personalized Media are licensed by 'Page Views per month' — so billing is multi-metric and only available via custom quote, not a single flat per-user or per-GB rate.
Not disclosed publicly — pricing page routes to Request Demo / Contact Sales only, no tiers, per-SKU/per-user/per-asset pricing, or plan names shown

“Not checked” means exactly that: we have not verified it, not that the platform lacks it. Every other value was read off the vendor’s own pages on the date shown on each platform page.
