Wikibase Resistance (2021 - )

In brief 

Initiated by the Cegesoma in the spring of 2021, the Wikibase Resistance project aims to provide a research tool on people who were involved in resistance activities in Belgium during World War II. Led by Fabrice Maerten, Anne Chardonnens, and a team of over 15 people with varied expertise, this long-term project is intended to collect and publish information from forms and personal files kept at the CegeSoma and other repositories of the State Archives. Hosting structured, multilingual, human- and machine-readable data, this knowledge base will allow searching among several hundred thousand descriptions of about 150,000 resistance fighters, starting from a name, a date of birth, or a place of residence.           


The objectives of the project are multiple: on the one hand, the WikiBase Resistance aims to centralize the data dispersed among different physical repositories and digital files, in order to improve access to the CegeSoma collections, as well as their visibility. On the other hand, this optimization allows us to better take into account the requests of our public concerning individuals, while exploring new ways of querying data. Indeed, this pilot project is part of a larger context marked by the emergence of a new international standard for archival description Records in Contexts based on making data available in machine-readable formats.


The Wikibase Resistants knowledge base is based, as its name indicates, on the free software Wikibase, which ensures the functioning of the generalist knowledge base Wikidata.

It allows to store multilingual data in an accessible and easily reusable format, readable by machines. In this case: data about resistance fighters. At its creation, each Person entity receives a unique identifier, a description, and semantic fields used to endow the entity with properties. To allow its identification, each person is described using a minimum of six properties:

  • Last name
  • First name(s)
  • Date of birth
  • Residence (in Belgium or abroad)
  • Reference of the associated archive
  • Inventory number
  • In some cases, the data will be enriched with other types of information such as gender, nationality, profession, resistance movement and/or network to which the person belonged, a date of arrest or death, etc.

Currently, the data encoding is focused on the forms and personal files contained in the archival funds kept by CegeSoma. Namely, the funds (complete or partial) of :

Later on, we will integrate the information contained in the individual files of civilian resistance fighters, contributors to the clandestine press, and political prisoners kept by the Service Archives des Victimes de la Guerre. Finally, the project should also include the data contained in the files of all armed resistance fighters produced by the Office of the Resistance and kept by the State Archives of Belgium.

Open and Linked data

The project also aims to interconnect these data with external databases, in order to offer more contextual information and to decompartmentalize the collections. Steps are thus taken to align people with possible corresponding Wikidata entities, while places (of birth, residence, or death) are associated with external resources such as Wikidata or GeoNames. These data associations allow the retrieval of other references, such as ODIS or SNAC (Social Networks and Archival Context) identifiers, which can help users locate other resources or archival collections in Belgium or abroad.

By moving from a logic of data in silo to one of data openness, CegeSoma is thus fully in line with the digital transition at work in the archive sector.

As an indication, a beta version of the knowledge base, created within the framework of Anne Chardonnens' doctoral thesis, is accessible at the following address: adochs.arch.be.

At present (October 2021), 52% of the individual files have been described using at least the basic information mentioned above.
