DPGs for AI Collection
All DPGs included in the DPGs for AI Collection must meet the requirements outlined in the DPG4AI collection criteria.
The information below reflects the self-reported responses provided as part of the assessment process.
Solution Type: Open Data
DPG Compliance & Profile Page: https://www.digitalpublicgoods.net/r/wikidata
Description: Wikidata is Wikimedia's open community-curated knowledge graph. It acts as central storage for the structured data of its Wikimedia sister projects, including Wikipedia, Wikivoyage, Wiktionary, Wikisource, and others.
Assessment Status: Under Review
Review Date: 2026-06-14
Category Fit:
Open Data (CC0-1.0). Wikidata is a community-curated, structured knowledge graph (120M+ items) used for entity linking, knowledge-graph grounding, retrieval/RAG and as training/evaluation data. Lifecycle roles: Data Acquisition & Preparation and Model Building & Training. https://www.wikidata.org
AI Lifecycle Utility:
Documented Relevance/ Impact:
Widely used in AI: KG embeddings, entity linking, fact-checking, RAG grounding, and SPARQL question-answering datasets. 20B+ RDF triples; public SPARQL endpoint (Wikidata Query Service). CC0 makes it maximally reusable. Data access: https://www.wikidata.org/wiki/Wikidata:Data\_access
Adoption Readiness Level:
L4 Orchestrated / Optimized
Adoption Readiness Evidence:
Versioned JSON/RDF/XML dumps with documented schema, MediaWiki/Wikibase API, and a public SPARQL endpoint for programmatic access. Database download docs: https://www.wikidata.org/wiki/Wikidata:Database\_download
Interoperability Level:
L4 Metadata-Rich — machine-readable metadata (CSVW/schema.org/Dataset) available
Interoperability Evidence:
Open AI-compatible formats: RDF (Turtle/N-Triples), JSON, plus CSV/SQL extraction and a SPARQL API. Structured by design with controlled properties. Native Croissant manifest not published (→ not L5), though third-party HF mirrors exist (e.g. wikidata-truthy). https://www.wikidata.org/wiki/Wikidata:Data\_access
Responsible Practices Level:
L2 Minimum Disclosure — known limitations and collection context stated (narrative form)
Equity & Inclusion:
Responsible Practices:
Standards & Vocabularies:
Responsible Practices Evidence:
Collection context transparent (community-curated, notability policy). Known coverage/representation biases discussed by the community; provenance via references and statement ranks. No formal datasheet / Croissant-RAI → L2. Notability policy: https://www.wikidata.org/wiki/Wikidata:Notability
