Description
Sophymarine created a precomputed mapping between Wikidata items for companies and their canonical OpenRegistry URLs. The dataset, versioned 1.0.0 and cited via Zenodo, was last updated on May 24, 2026. It includes rows for Wikidata items that have at least one supported national company-registry identifier statement.
Use Cases
Enriching company profiles in knowledge graphs based on the provided Wikidata-to-registry mapping.
Linking disparate corporate data sources using the canonical OpenRegistry URLs as a common identifier.
Validating and auditing company identifier statements within Wikidata entries.
Building datasets for training entity linking models focused on corporate entities.
Strengths
Provides a direct, precomputed alignment between two major entity sources: Wikidata and OpenRegistry.
Focuses on entities with verified national company-registry identifiers, which suggests a basis in official records.
Dataset is versioned and has a formal citation (DOI: 10.5281/zenodo.20363013).

Row count is unknown, which may limit suitability assessment for large-scale projects.
