Featured story
Assimil: from publishing files to digital products at scale.
Assimil's challenge was not simply to create an app. It was to give a traditional publisher the technological infrastructure required to turn its existing editorial production into a scalable digital catalogue.
The source already existed: structured XML files used in the publishing workflow for print. Holiwave designed a production system capable of ingesting that content, enriching it with audio, interactions and learning logic, generating complete digital courses, and publishing them as applications across mobile and desktop platforms.
The objective was not to reproduce books on screens.It was to transform an editorial workflow into a digital production pipeline.

1The challenge
Assimil had the content and the expertise. What it lacked was a system to turn that material into interactive software efficiently and at scale.
Reuse the source
Start from the XML already used for publishing.
Preserve editorial control
Keep the publisher in charge of its content.
Scale the catalogue
Make one investment that serves many methods.
2The infrastructure

Holiwave built the tooling that bridges editorial production and software production.
Structured XML is imported and transformed into a digital learning model. Content, audio, exercises, metadata and interactions are assembled through a controlled production process, then rendered by the applications for each supported platform.
The same editorial source can feed multiple digital products without rebuilding the course by hand for every device or operating system.
3From automation to industrialisation
Once the production chain was in place, adding a new Assimil method no longer meant creating a new application from scratch.
Import the editorial source, validate and enrich the content, generate the digital course, test it, and publish it through the relevant stores.

One product. Three lives.
2014
In 2014, Yota was preparing an unusual smartphone: a colour screen on the front and an e-paper screen on the back. Mantano ported its EPUB and PDF engines and worked with the specific SDK controlling that second display.
Display, interaction and refresh did not use the usual Android interfaces. The project reused expertise acquired seven years earlier on e-readers and applied it to a device nobody had had to design before.
2015 — 2016
Jean-Marie Geffroy joined the Readium Foundation board in 2015, then the European Digital Reading Lab board in 2016.
Mantano developed the very first implementation of Readium LCP, a protection designed to be far less intrusive for readers. Rather than keep it proprietary, the company donated its source code to the Readium Foundation, giving EDRLab a concrete base for further development and adoption of LCP.
Official announcement on the EDRLab website.
We also collaborated with the New York Public Library on its digital library project.
Recognition
Mantano Reader directly demonstrated what the team could build. Manufacturers, carriers, publishers and libraries then approached Mantano for their own products.
