Working together has never been as easy

Based on the technology Java/J2EE, LibreSource rests on an innovative concept that brings great flexibility: to create a LibreSource site, you have a large number of functional building blocks, the resources. With a simple click you compose your web portal online according to your needs, selecting the resources of your choice, available at your convenience. Among the resources offered by LibreSource, are Wiki pages, downloading areas, forums, forms, etc.


Effective communication is a fundamental prerequisite for agile project management. LibreSource facilitates communication between members of your project by means of its integrated forum and instant messaging based on Jabber's open protocol. LibreSource simplifies the creation of a dynamic user community and helps team members maintain and improve the effectiveness of their cooperation.


LibreSource is completely customizable, making each site based on this solution unique:

– The look of the site (logos, colors, tabs) is controlled by CSS style sheets and can be adapted to the graphic guidelines of each project.
– The structure of the site is completely modular according to your needs. It is based on a hierarchical structure similar to a file system, dynamically managed by LibreSource.
– Page composition is entirely customizable because nearly every page can be edited online by a Wiki, allowing the use of text, images, tables, etc.

High security

Since its conception, LibreSource integrates a precise control of the rights of access for all the functionalities offered and the files hosted. On a single server, LibreSource can therefore host many projects and many user groups.
You can assign permission to read, write, create or delete to each user or group of users. Access rights settings are totally dynamic and can be modified as the project evolves.

A first-rate experience at your service

In support of LibreSource Artrenum offers a coherent collection of professional services adapted to your needs. Its team has extensive experience in the deployment of LibreSource solutions for the scientific community and in high tech. Its many references include:

Since 2004, Artenum has hosted the industrial and scientific user community, SPINE specialized in plasma/satellite interaction, on behalf of the account of the European Space Agency (ESA) and CNES (French Space Agency). This user group currently combines more than 250 members and shares more than 20 gb of scientific data (source code, articles, documents, simulation data). The use of LibreSource by SPINE was awarded the special prize by the ObjectWeb jury in 2006.

Several research communities and major industrial accounts have shown confidence in Artenum and have chosen LibreSource for their collaborative web portal.

Enjoying a large dynamic community of users, LibreSource has known numerous deployments in the heart of the open source and academic communities in France and Europe (notably Växjö University, Sweden).

LibreSource: technical specifications


  • Collaborative platform, modular and extensible based on the composition of resources;
  • Administration online: update the content of your site yourself, without needing technical competence;
  • Hierarchical and flexible structuring of resources, similar to file systems, dynamically managed by LibreSource;
  • Easy navigation on the platform thanks to an accessible navigation menu, no matter what page is displayed, as well as a complete navigation road map that allows users to find their way easily;

  • Import/export in XML of any subset of the entire resource hierarchy to facilitate migrations and updates to the platform.


  • User
    The resource "user" contains the preferences of the user of the platform: surname, first name, email address, presentation, options, etc. One can assign each user the rights to read, write, create and delete each platform resource.
  • Group
    A group consists of a certain number of users. Therefore it is easy to assign access rights to resources as a function of the user group.
  • History
    The history of a resource list for all the changes made to the resource (and possibly the related resources) with the date of modification and author making it easy to follow the modifications.
  • Wiki page
    A Wiki is an ideal tool for writing documentation online in a collaborative manner, for example. As in Wikipedia, each authorized user can easily modify and add pages thanks to Wiki syntax. You lay out a centralized common documentation from a shared draft.
