Exhibition

Info

The exhibition endpoint provides access to a single exhibition from the Design Museum Gent archive, enriched with multilingual titles, descriptions, and links to collection objects shown during the exhibition.

endpoint:

GET https://data.designmuseumgent.be/v2/id/exhibition/{PID}

# check if an exhibition exists
curl -k -I 'https://data.designmuseumgent.be/v2/id/exhibition/TE_2020-001'

example:

GET https://data.designmuseumgent.be/v2/id/exhibition/TE_2020-001

Response format

Data is returned as CIDOC-CRM compliant JSON-LD using the following vocabularies:

Prefix	Namespace
`crm`	http://www.cidoc-crm.org/cidoc-crm/
`owl`	https://www.w3.org/2002/07/owl#
`rdfs`	http://www.w3.org/2000/01/rdf-schema#
`xsd`	http://www.w3.org/2001/XMLSchema#
`prov`	http://www.w3.org/ns/prov#

Code	Description
200	Successful request returning a single exhibition as CIDOC-CRM JSON-LD
404	Exhibition not found
500	Server error

Fields

Basic identification

Field	Type	Description	Example
`@id`	URI	Internal DMG URI for the exhibition	`https://data.designmuseumgent.be/v2/id/exhibition/TE_2020-001`
`@type`	string	CIDOC-CRM class	`crm:E7_Activity`
`owl:sameAs`	string	External URI in the Stad Gent datahub	`https://stad.gent/id/tentoonstelling/530003726`
`rdfs:label`	string	Default label of the exhibition	`"Kleureyck. Van Eycks kleuren in design"`
`crm:P2_has_type`	object	Type classification using Getty AAT	`http://vocab.getty.edu/aat/300054755`

Warning

Stad Gent URIs (stad.gent/id/...) used in owl:sameAs are persistent identifiers but do not currently resolve. Getty, Wikidata and EU Publications Office URIs do resolve and return linked data.

Provenance — `prov:generatedAtTime`

Each record includes a prov:generatedAtTime timestamp indicating when the record was last harvested from the source system. This is not the date the object was created or modified in the museum's collection management system — it is the date the DMG API last processed and stored this record.

"prov:generatedAtTime": {
    "@type": "xsd:dateTime",
    "@value": "2026-04-28T10:38:46.7599119"
}

Field	Description
`@type`	Always `xsd:dateTime`
`@value`	ISO 8601 timestamp of the last harvest

Incremental harvesting

Use prov:generatedAtTime together with the ?modifiedSince= parameter to build efficient incremental sync pipelines — only fetch records that have changed since your last harvest:

GET https://data.designmuseumgent.be/v2/id/exhibitions?modifiedSince=2026-05-01&fullRecord=true

The ETag and Last-Modified response headers on single entity endpoints expose the same timestamp for HTTP cache validation:

Titles — `crm:P1_is_identified_by`

An array of crm:E41_Appellation and crm:E42_Identifier nodes.

`@type`	Description
`crm:E41_Appellation`	Multilingual title, one per language
`crm:E42_Identifier`	Internal DMG reference number (e.g. `TE_2020-001`)

Language tags

Each appellation includes a language tag using the EU Publications Office language authority:

Language	URI
Dutch	`http://publications.europa.eu/resource/authority/language/NLD`
French	`http://publications.europa.eu/resource/authority/language/FRA`
English	`http://publications.europa.eu/resource/authority/language/ENG`

Internal identifier pattern

All internal identifiers follow the pattern TE_{year}-{number} and are typed using: https://data.designmuseumgent.be/v2/id/type/intern-referentienummer

Time span — `crm:P4_has_time-span`

Field	Type	Description	Example
`crm:P82a_begin_of_the_begin`	`xsd:date`	Opening date	`"2020-03-13"`
`crm:P82b_end_of_the_end`	`xsd:date`	Closing date	`"2020-09-03"`
`rdfs:label`	string	Full period as ISO interval	`"2020-03-13/2020-09-03"`

Tips

Dates follow the ISO 8601 interval format YYYY-MM-DD/YYYY-MM-DD. For exhibitions with uncertain or open-ended dates, one of the two bounds may be absent.

Location — `crm:P7_took_place_at`

Field	Description	Example
`@id`	Wikidata URI of the venue	`https://www.wikidata.org/wiki/Q1809071`
`@type`	CIDOC-CRM class	`crm:E53_Place`
`rdfs:label`	Name of the venue	`"Design Museum Gent"`

Organiser — `crm:P14_carried_out_by`

Field	Description	Example
`@id`	Wikidata URI of the organiser	`https://www.wikidata.org/wiki/Q1809071`
`@type`	CIDOC-CRM class	`crm:E39_Actor`
`rdfs:label`	Name of the organiser	`"Design Museum Gent"`

Objects shown — `crm:P16_used_specific_object`

Array of objects from the DMG collection that were shown during the exhibition.

Field	Description	Example
`@id`	Internal DMG URI for the object	`https://data.designmuseumgent.be/v2/id/object/2016-0017`
`@type`	CIDOC-CRM class	`crm:E22_Human-Made_Object`
`owl:sameAs`	External URI in the Stad Gent datahub	`https://stad.gent/id/mensgemaaktobject/dmg/530022921`

Resolvable URIs

Each @id in crm:P16_used_specific_object is a resolvable URI — you can fetch full object metadata directly from it.

GET https://data.designmuseumgent.be/v2/id/object/2016-0017

Warning

Only objects that are present in the DMG collection database are included. Objects from the source data that cannot be matched are omitted.

Descriptions — `crm:P67i_is_referred_to_by`

Array of crm:E33_Linguistic_Object nodes, one per available language.

Field	Description	Example
`@type`	CIDOC-CRM class	`crm:E33_Linguistic_Object`
`rdfs:label`	Full description text	`"Waar komt kleur vandaan?..."`
`crm:P2_has_type`	Classifies this as a description	`http://vocab.getty.edu/aat/300080091`
`crm:P72_has_language`	Language of the description	`http://publications.europa.eu/resource/authority/language/NLD`

Info

Not all exhibitions have descriptions in all three languages. If a description is not available for a given language, that language node is omitted from the array entirely.
