Strengthen the quality of linkages and authority data

Go to IdRef

IdRef contribute to the quality of authority data

Forms are available from each record IdRef to allow Internet users to report any erroneous information, broken or missing links (...) or to propose bibliographical enrichment. 

In the logic of crowdsourcing, everyone can thus contribute to the quality of RHS authority data.

Please note: proposed amendments are not dealt with by the Abes. They are sent to the libraries that initially catalogued the authority records concerned and processed by them.

Rights relating to personal data

Within the framework of its national mission of reporting ESR documentary resources, the ESRAbes has authority files that may contain personal data (e.g. date of birth, form of name, country). These files have been filed with the CNIL, which authorized them.

In accordance with the RGPD, the exercise of the rights of information, access, rectification and opposition to personal data is guaranteed. If a user wishes that certain personal data concerning him/her is no longer available, a Data Rectification Request form is available in each notice IdRef so that everyone can exercise their right to rectification.

Please note: requests for data rectification are not processed by the Abes. They are forwarded to the libraries that originally catalogued the authority records concerned and are processed by them. strengthening the quality of links between records

In service since 2019, is a professional interface dedicated to the quality of the links between "natural persons" authority IdRef records and access points present in bibliographic Sudocrecords.

Developed by the Abes, according to the UX Design methodology (regular user tests and iterative processes), this application - user-friendly, even playful - is available to the network Sudoccataloguers.

Logo Paprika Go to Paprika offers a work environment adapted to the task of identifying authority records (or "natural person" entities) with similar or identical names in the case of homonyms, which leads to potential mismatches between records.

By using paprika.idref.frThe following features are available to library professionals:

  • adding or modifying links between records
  • rebound to the cataloguing module ofIdRef to create the missing authority records.
  • opportunity to build on the artificial intelligence service Qualinka which exploits the wealth of data and the links between these data (authoritative and bibliographical). As a decision support service, Qualinka provides a diagnosis of potential errors and suggests actions to the cataloguer.

A fruitful partnership between LIRMMAbes and LIRMM - GraphIK team

The application has been developed by the Abes by adapting an artificial intelligence service, developed in collaboration with the GraphIK team from LIRMM.

The heart of this service is an original and generic engine developed by the GraphIK team.

It is a linking engine between bibliographic Sudoc references and authority data. It can be parameterized (ontologies, attributes, filters, criteria, linking rules and differences, etc.) according to the problems specific to the type of linking between records.

The results provided are used by a diagnostic service (Brett's report) providing quality control information on the links of the Sudoc and suggestions for modification.

AlgoDoubles and AlgoLinks: detecting anomalies

Based on web services technology, itAbes provides network members (Cataloguing Correspondent, Authority Correspondent, CoordinatorSudoc , etc.) with two quality control tools synchronized in real time on the production Sudoc and IdRef.

These web services are called from a URL, to which different parameters can be added, for example to restrict the search to a particular batch (ILN, RCR, date ...). Once the data analysis process is completed, a report of anomalies is generated (.txt file downloadable). 


AlgoDoublons is a detector of potential authority duplicates.

Based on a clustering process carried out by VIAFAlgoDoublons is used to identify whether several records from VIAFIdRef are grouped together in the same VIAF "cluster": these may be true duplicates or records with erroneous bibliographic links.


AlgoLinks is a detector of missing links identified in the link fields of bibliographic Sudocrecords.

Anomaly reports: support for curing yards

Bug reports are particularly useful for quality and data cleansing projects. For cataloguers, they are real tracking files that guide them through the various stages of a "data quality" work plan. The necessary corrections are made from the appropriate applications (WinIBW, IdRef, Paprika).
