languageCode Field Distribution in the CLARIN Virtual Language Observatory -- Complete Solr Facet Export, 25 March 2026

This dataset contains the complete Solr facet export of the languageCode field from the CLARIN Virtual Language Observatory (VLO) index, as provided by the VLO technical team on 25 March 2026. Here, “complete” means complete with respect to all values present in the languageCode field at the time of extraction; it is not a complete metadata export of the VLO as a whole.

The dataset constitutes the primary empirical source for the analysis of linguistic distribution, representational concentration, and discoverability conditions in the VLO reported in the associated/forthcoming conference paper.

The VLO is the principal discovery interface for language resources across the CLARIN ERIC federated research infrastructure, aggregating Component Metadata Infrastructure (CMDI) records from national and institutional centres via OAI-PMH harvesting. The languageCode field is the principal mechanism through which users filter the VLO index by the language of a resource.
