Cultural Heritage Building Blocks

A person or organization associated with cultural heritage objects, events or activities — creators, custodians, restorers — modelled as a CIDOC-CRM E39 Actor and profiling the PROV-O Agent.

An EDM/ORE aggregation wrapping a heritage object together with its digital representations and the provider/rights metadata required to publish it to Europeana / ECCCH, modelled as edm:Aggregation (ore:Aggregation).

An interior room, bay, hall, zone or level within a building, modelled as CIDOC-CRM E22 Man-Made Object. Profile of heritage-object adding containment hierarchy, historical name crosswalk, floor/bay identifiers and optional IFC space reference.

A digital-representation profile constrained to archival document formats (PDF/A, LIDO/XML), with a mandatory persistent identifier for long-term archival reference.

A principal building or architectural unit as a CIDOC-CRM E22 Man-Made Object with spatial footprint and optional IFC/BIM reference. Profile of heritage-object.

A qualitative conservation inspection event (CRMsci E14 Condition Assessment) recording the condition state of a heritage object or place at a point in time, with assessor, method, severity and optional spatial localisation.

A processed output derived from a geometric survey dataset — section drawing, triangulated mesh, deviation map or registration report — modelled as a CRMdig D9 Data Object. Profiles ogc.heritage.digital-representation, adding a mandatory PROV derivation link to the parent survey dataset and a structured CRMdig D10 Software Execution sub-object recording the processing parameters.

A digital asset (image, 3D model, document...) representing or documenting a heritage object, modelled as a CIDOC-CRM E73 Information Object and profiling the PROV-O Entity.

Feature-envelope wrapper for Digital Representation: a spatially located digital asset encoded as a GeoJSON/JSON-FG Feature, or as a topo-feature when geometry is defined by reference/topology.

A digital file produced by digitising a physical source carrier (e.g. a photograph, drawing or bound volume), modelled as a CRMdig D1 Digital Object with a mandatory PROV derivation chain linking to the source-carrier and a D7 digitisation event sub-object. Profiles ogc.heritage.digital-representation.

An event in the history of a heritage object — production, restoration, modification, acquisition — modelled as a CIDOC-CRM E5 Event (generalising E12 Production and E11 Modification) and profiling the PROV-O Activity.

A digital-representation profile constrained to physical-fabrication formats (STL, 3MF), with a mandatory PROV derivation chain back to its source 3D model.

The ECCCH Heritage Digital Twin Ontology's HC2 Heritage Digital Twin: the aggregate of formal proposition sets documenting one heritage entity, identified by its propositional content and creating actor rather than by instance identity.

A physical cultural heritage item — an artwork, building element, garden feature or museum object — modelled as a CIDOC-CRM E22 Man-Made Object.

Feature-envelope wrapper for Heritage Object: a spatially located CIDOC-CRM E22 Man-Made Object encoded as a GeoJSON/JSON-FG Feature, or as a topo-feature when geometry is defined by reference/topology.

The ECCCH Heritage Digital Twin Ontology's HC16 Heritage Proposition Set: a named-graph content unit — what an HC2 Heritage Digital Twin actually contains, referencing the rest of this register's HDTO-typed content.

A designated heritage site or pilot area, typed as CIDOC-CRM E27 Site. Extends 'place' with site-level designation, responsible organisation and rights fields.

A named historical spatial feature — room, area, route or landscape designation — that has since been renamed, restructured or disappeared, mapped to its current spatial equivalent with a confidence rating (CIDOC-CRM E53 Place + P89, CRRS-015).

A piece of historical knowledge extracted from a document or legacy record — an attribution, identification, date assignment or annotation — modelled as a CIDOC-CRM E13 Attribute Assignment with an inner E33 Linguistic Object and a W3C Web Annotation evidence locator pointing to the source passage.

A physical sensor or monitoring device installed at a heritage resource, modelled as a SOSA Sensor with a CIDOC-CRM E22 Man-Made Object identity layer. Profiles ogc.sosa.properties.sensor.

A conservation threshold rule bounding an environmental parameter at a heritage monitoring point or zone, modelled as a SOSA ObservableProperty with QUDT unit and severity annotations (CRRS-011).

A scientific observation or measurement of a heritage object or place — environmental monitoring, condition assessment, conservation science — profiling the SOSA/SSN Observation. `hasFeatureOfInterest` ties the reading back to the heritage object or place being measured (CIDOC-CRM/CRMsci's scientific observation context); `madeBySensor` is expected to reference an ogc.heritage.monitoring-point (SOSA/SSN Sensor) record. Required HDTO co-type: crmsci:S4.

An audio or video oral history recording or community narrative, modelled as a CIDOC-CRM E73 Information Object with a mandatory IIIF Presentation API manifest, interviewee reference, language, and consent status. Profiles ogc.heritage.digital-representation and adds schema.org AudioObject/VideoObject alignment for web visibility.

A spatial location relevant to cultural heritage — a site, building, room or landscape feature — modelled as a CIDOC-CRM E53 Place and encoded as an OGC JSON-FG Feature.

A road, visitor path, internal track or circulation route within or between heritage zones, typed as CIDOC-CRM E26 Physical Feature. Profiles 'place', inheriting JSON-FG geometry and core CRM place attributes, and adding route type, surface, width, accessibility and permitted-use fields.

A physical original document, photograph, drawing, negative or bound volume that carries heritage information, modelled as CIDOC-CRM E31 Document. Records the physical carrier from which digital surrogates are derived, with repository, archival code, and rights metadata.

A material finish layer or physical surface feature recognised on an architectural component or heritage object (CIDOC-CRM E25 Man-Made Feature), documenting material, application technique, historical phase and spatial footprint (CRRS-005).

A geometric survey dataset (point cloud, photogrammetric model or similar) acquired from a heritage asset, modelled as a CRMdig D1 Digital Object with a CRMdig D7 acquisition event and a spatial coverage geometry. Profiles ogc.heritage.digital-representation, adding survey acquisition paradata (method, equipment, CRS, density, accuracy) and a mandatory coverage polygon.

A digital-representation profile constrained to real-time 3D model formats (glTF, 3D Tiles, OBJ), for 3D documentation and web rendering of heritage objects.
