Source: Linked Art to Schema.org mapping notes supplied for project reference. This is a project summary; the upstream mapping notes and Schema.org vocabulary remain authoritative.
Purpose
This mapping describes how Linked Art records can be projected into Schema.org for web-indexing, structured-data, and broad consumer discovery use cases. Linked Art remains the canonical semantic model for Meta Museum; Schema.org should be treated as a derivative public-web projection.
Shared Properties
Common Linked Art fields map across many Schema.org entity types:
- `id` maps to `url`.
- Description Statements map to `description`.
- `classified_as.id` maps to `additionalType`.
- Primary `Name` content maps to `name`; other `Name` content maps to `alternateName`.
- `Identifier` content maps to `identifier`.
- `equivalent.id` maps to `sameAs`.
- Representation image access points map to `image`.
- Subject web pages map to `mainEntityOfPage`.
People And Organizations
Linked Art `Person` records project to Schema.org `Person`:
- Birth and death timespans map to `birthDate` and `deathDate`.
- Birth and death places map to `birthPlace` and `deathPlace`.
- Email contact points map to `email`.
- Gender, occupation, and nationality classifications map to `gender`, `hasOccupation`, and `nationality`.
- Residence maps to `homeLocation`.
- Group membership maps to `memberOf`.
Linked Art `Group` records project to Schema.org `Organization`:
- Email and address contact points map to `email` and `address`.
- Formation and dissolution dates map to `foundingDate` and `dissolutionDate`.
- Formation place maps to `foundingLocation`.
- Formation actors map to `founder`.
- Residence maps to `location`.
- Membership maps to `memberOf`; hierarchical membership can map to `parentOrganization`.
Places And Concepts
Linked Art `Place` records project to Schema.org `Place`:
- `part_of.id` maps to `containedInPlace`.
- `defined_by` geometry maps to `geo`, or to `latitude`/`longitude` when the value is a point.
- If a representation is specifically a map, use `hasMap` rather than generic `image`.
Linked Art concept records project to Schema.org `DefinedTerm` and `CreativeWork`; language concepts also carry the `Language` additional type:
- `broader` maps to `isPartOf`.
- `member_of` maps to `inDefinedTermSet`.
Human-Made Objects
Linked Art `HumanMadeObject` records project to Schema.org `VisualArtwork` or `ArchiveComponent` depending on object type:
- Object classification maps to `artform`.
- Description Statements map to `abstract` for human-made objects.
- Rights, access, credit, and material Statements map to `copyrightNotice`, `conditionsOfAccess`, `creditText`, and `artMedium`.
- Production actors map to `creator` or `artist`; contributor-classified production parts map to `contributor`.
- Production country maps to `countryOfOrigin`; production timespan maps to `dateCreated`; production place maps to `locationCreated`.
- Part hierarchy maps to `isPartOf`.
- Shown or carried content maps to `exampleOfWork`.
- Materials map to `material`.
- Text content maps to `text`.
- Height, width, and depth dimensions map to `height`, `width`, and `depth`.
- Current owner maps to `holdingArchive`; current location maps to `itemLocation`.
Digital Objects
Linked Art `DigitalObject` records project to Schema.org `CreativeWork` and `DataSet`:
- Digitally shown or carried content maps to `exampleOfWork`.
- Height, width, and depth dimensions map to `height`, `width`, and `depth`; other dimensions can map to `size`.
- Part hierarchy maps to `isPartOf`.
- Format maps to `encodingFormat`.
- Access points map to `distribution`.
- Creation actors map to `creator`.
- Publishing activity actors map to `publisher`.
Visual And Textual Works
Linked Art `VisualItem` and `LinguisticObject` records project to Schema.org `CreativeWork`:
- `about` maps to `about`.
- Represented places map to `contentLocation`.
- Other represented entities map to `mainEntity`.
- Language maps to `inLanguage`.
- Genre classifications map to `genre`.
- Creation actors map to `author`, `artist`, or `creator` depending on work type and role.
- Publishing activity actors map to `publisher`.
- Content maps to `text`.
- Dimensions map to `size`.
- Format maps to `encodingFormat`.
Events And Sets
Linked Art `Event` records project to Schema.org `Event`, with exhibitions projecting to `ExhibitionEvent` where appropriate:
- Responsible actors map to `organizer`, `performer`, or `contributor`.
- Places map to `location`.
- Event hierarchy maps to `superEvent`.
- Timespan bounds map to `startDate` and `endDate`.
- Used specific objects map to `workFeatured`.
- Influences can map to `about` when the relationship is suitable for broad web discovery.
Linked Art `Set` records project to Schema.org `ArchiveComponent` for archives or `Collection` for other sets:
- `member_of` maps to `isPartOf`.
- Creation actors map to `author`, `artist`, or `creator`.
- Publishing activity actors map to `publisher`.
- `about` maps to `about`.
- Dimensions map to `size`.
Meta Museum Notes
Meta Museum should generate Schema.org from canonical Linked Art records, not maintain it as a second source of truth. The projection is useful for search engines, simple external clients, and evaluator-facing web-readability checks, but it is intentionally less precise than Linked Art.
Use `sameAs` from `equivalent` carefully: it is suitable for broad web structured data, but Linked Art reconciliation still keeps `equivalent` semantics separate from a hard identity-collapse model.
Test Ideas
- Derive Schema.org JSON-LD from Linked Art records at render/export time rather than storing duplicate assertions.
- Preserve Schema.org `sameAs` projection from Linked Art `equivalent` without weakening internal reconciliation semantics.
- Map object dimensions, image access points, names, identifiers, and descriptions from structured Linked Art fields.
- Keep human-made object, digital object, visual/textual work, event, set, person/group, place, and concept projections type-specific.
- Verify Schema.org output does not replace or mutate canonical Linked Art JSON-LD.
