Our day-to-day work moves between the CollectiveAccess ecosystem (Providence + Pawtucket) and everything that gravitates around it: applications, internal tools, integrations. We rarely code from scratch — we extend, connect and publish.
To extend Providence — domain interfaces, imports, exports, validations.
Public sites tailored to the institution's design, faceted browsing, viewers.
iOS and Android — gallery guides, geolocated trails, audio description.
Catalogues raisonnés, exhibition micro-sites, editorial portals.
NFC-based inventory checks, barcode readers, tablet-based data entry interfaces.
Three.js for objects, dataviz for corpora, analytical audio readings.
Imports from Joconde, Mistral, FileMaker, Excel — exports to OAI-PMH, RDF, Getty.
To expose a database to partners, feed an app, syndicate content.
An OBJ viewer in Three.js embedded in Pawtucket: the 3D object appears in the work's record, manipulable with a finger on tablet or with a mouse in the gallery. Stable for several years now, used in production on museum databases and catalogues raisonnés.
A bespoke plugin designed to generate computerised inventory registers in line with the Musées de France standards, organise inventory check minutes, and access the registers of allocated or deposited assets. Once an object is recorded, its inventory line becomes non-editable — as the regulation requires.
The component that lets you connect a reader for mobile inventory checks, for triggering media playback in an exhibition space, for starting an interactive piece or identifying a visitor in a game.
Collaborative mindmap to align needs and feasibility.
Lightweight Gantt chart, clear milestones, intermediate deliverables.
Short cycles in the Agile/XP spirit — show early, adjust quickly.
Acceptance, user training, source code handed over with the project.
Security is not an option you bolt on at the end. It is woven into the code, the infrastructure and our operational routines — aligned with the OWASP Top 10 and the GDPR.
TLS on every domain, Let's Encrypt certificates renewed automatically, forced HTTP → HTTPS redirection. No plain-text port exposed.
Prepared statements (anti-SQLi), context-aware output escaping (anti-XSS), CSRF tokens on write forms. Manual review on every PR.
Hashed passwords (bcrypt/argon2), HttpOnly + SameSite sessions, short expiry. Per-field and per-record permissions in CollectiveAccess.
Debian stable, CollectiveAccess, plugins, libraries — patched on a regular cadence. Monitoring of relevant CVEs, critical fixes applied within 72 h.
SQL + media rsync to separate storage, point-in-time over 30 days. Quarterly restoration tests — an untested backup is not a backup.
Data hosted with OVH (Roubaix, Gravelines), no transfer outside the EU by default. Minimised logs, anonymisation/erasure on request, processing register kept up to date.
Anything that can be reused by other institutions or contributors is published on GitHub. Here is a sample; the rest is free to explore on github.com/ideesculture and github.com/gautiermichelin.
A bridge between WordPress and CollectiveAccess. Distributed on wordpress.org.
An information service that queries the Tematres API for thesauri.
Quick editing of monolingual lists in Providence.
Library mode: loans/returns via barcode reading.
Handling of dates from the French Revolutionary calendar.
Defining custom dates and periods without touching the .conf.
Extensible user menu for Providence.
Software dedicated to managing paper archives and documents in companies and organisations.
Public documentation for the muséesDeFrance plugin.
Windows installer for training and learning purposes.
Public documentation pages and redirects.
Clear scope, fixed price, milestones. Ideal for a plugin, a site, a well-framed integration.
For ongoing evolutions or exploration phases where the scope keeps shifting.
Bundled with hosting or standalone — fixes, version upgrades, advice.
Unless otherwise requested — sensitive data, strategic agreement — our developments are released under GPL or MIT. The institution keeps the advantage of bespoke work; the community benefits; you in turn benefit from external contributions.
