CIDOC CRM (Conceptual Reference Model)

What it is CIDOC CRM is a formal ontology and information-integration framework for cultural heritage documentation. It supplies definitions and a formal structure for the concepts and relationships needed to query and explore diverse, dispersed datasets in a software- and schema-agnostic way.

Key concepts

• CRMbase provides the basic cultural-heritage classes and relations.
• Harmonized modular extensions support specialized areas such as bibliographic documentation and geoinformatics while remaining compatible with the base model.
• The model is intended as a shared semantic framework and common language for domain experts and system implementers.
• CIDOC CRM is an official ISO standard; the fetched page identifies ISO 21127:2023 as superseding ISO 21127:2014.

How you’d use it Model or map museum, library, archive, and related heritage information to a common semantic framework, then integrate and query facts across source systems. Use CRMbase for the shared core and a harmonized extension when a research question needs a specialized model.

LLM angle none stated

Pitfalls & lessons The page calls CIDOC CRM a living standard, so implementers should identify the official version and relevant extensions rather than assume one fixed model. Its role is semantic mediation across existing sources, not dependence on a particular software product or schema.

Verdict A mature, ISO-recognized semantic backbone for integrating heterogeneous cultural-heritage information, with a base ontology and compatible domain extensions.
