Digital services

The Mathrice network supports research in mathematics and offers a space for exchange and mutual assistance between computer scientists. Mathrice is developing a national infrastructure of online IT services and resources for French mathematicians through an online platform for mathematics (Plateforme en Ligne pour les Mathématiques – PLM).

The ties between Mathdoc and Mathrice were strengthened through the Portail Math project, with Mathrice helping to develop the digital services and achieve the extensive integration of the digital services into the more documentary aspect of the portal. For its part, the Mathrice network hosts the OJS open source editorial management software used for some of the centre Mersenne’s journals.

The Mathdoc team regularly speaks at the Mathrice days events to inform its members about the development of Mathdoc services or to provide training in its areas of expertise. Mathdoc also helped organise the Mathrice days and the RNBM-Mathrice joint session in Grenoble in April 2014.

GRICAD is a support unit (UAR) created on January 1, 2016 to meet scientific challenges related to the need for high-performance computing and data. Its supervisory authorities are CNRS, Université Grenoble Alpes, Grenoble-INP and INRIA. GRICAD supports research units and shares the site’s data centres and platforms with the teaching and administration units.

Mathdoc hosts part of its data at two data centres located in Grenoble on the university campus of Saint Martin d’Hères:

• The IMAG data centre (DC-IMAG)
• The data centre managed by UGA’s Shared Information Systems Department (DC-DSIM)

The IMAG data centre earned Code of Conduct certification in 2020 from the Joint Research Centre of the European Commission (EU-JRC) for the work carried out by the technical committee of the GRICAD/UGA data centre.

Crossref is a Digital Object Identifier (DOI) registration and registry agency, developed by the Publishers International Linking Association (PILA), a non-profit organisation under U.S. law.

Mathdoc became a member of Crossref in 2011, and is therefore entitled to assign DOIs to scientific articles published by centre Mersenne, and to register them in the Crossref system. Crossref also provides a service for obtaining DOIs from a bibliographic reference (by matching).

CLOCKSS (Controlled Lots of Copies Keep Stuff Safe) was founded in 2006 as a joint initiative of libraries and academic publishers. It aims to build a geographically distributed global archive that will ensure the long-term preservation of electronic scientific publications. It operates 12 archive nodes with renowned international academic institutions.

CLOCKSS uses a LOCKSS (Lots of Copies Keep Stuff Safe) archiving approach that was created by Stanford University librarians in 1999. The digital content is stored in the CLOCKSS archive without user access unless an activation event occurs. It only gives access to journals in the extreme case of a publisher ending its distribution of the content (dark archive).

As the only closed archive that assigns a Creative Commons license to all activated digital content, CLOCKSS supports the global academic community by providing permanent open access to abandoned and orphaned publications. The retrieved content therefore becomes perpetually available to anyone with internet access. Centre Mersenne uses CLOCKSS services to ensure the long-term archiving of its articles.
