The ISSN IC, with the support of Thomas Francart (SPARNA Company), has initiated a data upload project in Wikidata to validate and enrich metadata associated with continuing resources. A data model was discussed with the Wikidata community and a dedicated bot, i.e. ISSN Bot, has been designed to perform regular updates. This project has already completed 125,118 Wikidata items corresponding to journal titles by adding specific data, i.e. ISSNs for print and online editions, ISSN-L, key title, language, country of publication and URLs.
