FROM CLASSIC / S

Omeka

WE MIGRATE YOUR DATA TO

CollectiveAccess

Omeka (Classic or S) is an excellent CMS for heritage publishing — but first and foremost it is a publishing tool, not a collections management base. No loan management, little inventory management, a data model centred on Dublin Core. When the need for a real documentary management tool arises — inventory, inventory check, movements, exhibitions, conservation — we move your Omeka into CollectiveAccess, which also handles the back office.

LOCK · MANAGEMENT OPEN
Omeka publishing only
2-in-1
BACK OFFICE + PUBLIC SITE
CollectiveAccess handles inventory, inventory checks, loans and exhibitions — and publishes via Pawtucket. You keep the visitor-side comfort of Omeka, plus the rigour of a real base.

Pawtucket — faceted public site, more collections-oriented
Inventory management
No structured inventory numbers, no inventory check
Full inventory, ten-yearly inventory check, deaccessioning — Musées de France compliant
Loans & movements
No native management — handled outside Omeka
Built-in loans, exhibitions and movements module — condition reports, conservation
Joconde / muséesDeFrance export
External plugins, poorly maintained
Official plugin: inventory, ten-yearly inventory check, deaccessioning
Long-term viability

Sovereignty & hosting
Already in hand — depending on your current hosting

Hosted in France (OVH), GDPR-native, automated backups

★ Three gains change the game: a real management tool (and not just a publishing one), an inventory compliant with Musées de France, and the handling of loans and movements. Everything else — durability, openness, interoperability — flows from there.

— Guarantees
03

Four safety nets.

Included
01 INTEGRITY

Data preserved

No loss. Every Micromusée field finds its equivalent — including hierarchies, controlled vocabularies and media links.

02 ACCEPTANCE

Tested round-trip

Before going live, you work on a copy of your real database, in pre-production. Adjustments are free of charge.

03 SOVEREIGNTY

You stay in control

The server is hosted by us, but the database and the media belong to you. Full export available at any time, in an open format.

04 COST

No hidden licence

Once migrated, no more purchase or extension fees. You pay for hosting and support, that's it.
