Wikidata:WikiProject Heritage institutions/Data structure

Home

The present page contains overview tables of properties that are commonly used in connection with Wikidata items relating to heritage institutions. It further contains references to relevant vocabularies and ontologies as well as to mappings to infobox templates of various Wikipedia language versions. The typology of heritage institutions is covered in a separate section.

Specific data modelling issues are tackled on a separate page: Data Modelling Issues.

General

Title	ID	Data type	Description	Examples	Inverse
instance of	P31	Item	instance of: that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform)	Swiss National Library <instance of> national library	-
part of	P361	Item	part: object of which the subject is a part (if this subject is already part of object A which is a part of object B, then please only make the subject part of object A), inverse property of "has part" (P527, see also "has parts of the class" (P2670))	Swiss Literary Archives <part of> Swiss National Library	has part(s)
parent organization	P749	Item	parent company: parent organization of an organization, opposite of subsidiaries (P355)	Swiss National Library <parent organization> Federal Department of Home Affairs	has subsidiary
has part(s)	P527	Item	has part, consist of and meronymy: part of this subject; inverse property of "part of" (P361). See also "has parts of the class" (P2670).	Museum Aargau <has part(s)> Legionary Trail Vindonissa	part of
official name	P1448	Monolingual text	official name: official name of the subject in its official language(s)	Germany <official name> Bundesrepublik Deutschland	-
legal form	P1454	Item	legal form: legal form of an entity	Haribo <legal form> GmbH & Co. KG	-
director / manager	P1037	Item	leader of organization: person who manages any kind of group	Louvre Museum <director / manager> Jean-Luc Martinez	-
chairperson	P488	Item	chairperson, leader and president: presiding member of an organization, group or body	Rijksmuseum <chairperson> Jaap de Hoop Scheffer	-
image	P18	Commons media file	illustration and image: image of relevant illustration of the subject; if available, also use more specific properties (sample: coat of arms image, locator map, flag image, signature image, logo image, collage image)	Swiss National Library <image> Swiss National Library building.jpg	-
Commons category	P373	String	Commons category: name of the Wikimedia Commons category containing files related to this item (without the prefix "Category:")	Swiss National Library <Commons category> Swiss_National_Library	-

Note:

instance of (P31): Use a type as specific as possible from the typology of heritage institutions. Not all libraries are "heritage institutions" in the sense proper, as they may not have a heritage collection of their own. The same may go for some other institutions being listed on museum inventories and the like (e.g. exhibition centres). In order to declare specifically that an institution has curatorial care over a collection, use instance of (P31) memory institution (Q1497649). Check the mapping for the Swiss GLAM Inventory for an example on how the information in the source file was mapped to various types of heritage institutions contained in Wikidata.

Open issues:

director / manager (P1037) vs. chairperson (P488) – which one should be used by default?
To what extent should the typology of heritage institutions be used to characterize various types of institutions? Alternatively, it has been suggested to use main subject (P921) instead.^[1] It should however be noted that the typologies presently used are mutli-dimensional and do not exclusively focus on the subject/theme of an institution.

Location

Title	ID	Data type	Description	Examples	Inverse
country	P17	Item	historical country, state and sovereign state: sovereign state that this item is in (not to be used for human beings)	Swiss National Library <country> Switzerland	-
located in the administrative territorial entity	P131	Item	administrative territorial entity: the item is located on the territory of the following administrative entity. Use P276 for specifying locations that are non-administrative places and for items about events. Use P1382 if the item falls only partially into the administrative entity.	Swiss National Library <located in the administrative territorial entity> Bern	-
location	P276	Item	physical location: location of the object, structure or event. In the case of an administrative entity as containing item use P131. For statistical entities use P8138. In the case of a geographic entity use P706. Use P7153 for locations associated with the object	Louvre Museum <location> Louvre Palace	contains
street address	P6375	Monolingual text	address and street address: full street address where subject is located. Include building number, city/locality, post code, but not country; use also P669 if the street has its own separate item	Ashmolean Museum <street address> Beaumont Street, Oxford OX1 2PH	-
located on street	P669	Item	street: street, road, or square, where the item is located. To add the number, use Property:P670 "house number" as qualifier. Use property P6375 "street address", if there is no item for the street	Louvre Museum <located on street> rue de Rivoli	-
postal code	P281	String	postal code: identifier assigned by postal authorities for the subject area or building	Louvre Museum <postal code> 75058	-
coordinate location	P625	Geographic coordinates	geographic coordinates: geocoordinates of the subject. For Earth, please note that only WGS84 coordinating system is supported at the moment	Swiss National Library <coordinate location> 46°56'29"N, 7°26'59"E	-

Notes:

Use coordinate location (P625) for simple cases where an institution has only one site or if coordinates are indicated only for the main office. For more complex cases, use location (P276) to point to a building or various buildings and use coordinate location (P625) on the items for the buildings instead. Example: Museum Aargau (Q27485205).
Use located on street (P669) only if the street is different from the one indicated in street address (P6375) or if there is a pre-existing item for the street.
The use of postal code (P281) is debatable. Postal addresses (as opposed to the location address) have not been properly modeled in Wikidata yet. Indicating a postal code where the postal address and the location address differ may lead to confusion.

Significant Events in the Life of an Institution

Title	ID	Data type	Description	Examples	Inverse
inception	P571	Point in time	date of establishment, founding and date of the first award: time when an entity begins to exist; for date of official opening use P1619	Swiss National Library <inception> 1895	-
dissolved, abolished or demolished date	P576	Point in time	date of dissolution, abolition or demolition: point in time at which the subject (organisation, building) ceased to exist; see "date of official closure" (P3999) for closing a facility, "service retirement" (P730) for retiring equipment, "discontinued date" (P2669) for stopping a product	Pavillon Le Corbusier <dissolved, abolished or demolished date> May 2016	-
significant event	P793	Item	key event: significant or notable events associated with the subject	Rijksmuseum <significant event> construction	-

Note:

Use inception (P571) and dissolved, abolished or demolished date (P576) to indicate the opening and the dissolution of an institution respectively. If you want to represent more complex information, use significant event (P793) that allows for the distinction between the construction and the opening, the modeling of temporary closure and re-opening, etc. See Rijksmuseum (Q190804) for examples.

Properties of Buildings

Title	ID	Data type	Description	Examples	Inverse
instance of	P31	Item	instance of: that class of which this subject is a particular example and member; different from P279 (subclass of); for example: K2 is an instance of mountain; volcano is a subclass of mountain (and an instance of volcanic landform)	pavillon Gérard-Morisset <instance of> museum building	-

country	P17	Item	historical country, state and sovereign state: sovereign state that this item is in (not to be used for human beings)	Museum Tinguely <country> Switzerland	-
located in the administrative territorial entity	P131	Item	administrative territorial entity: the item is located on the territory of the following administrative entity. Use P276 for specifying locations that are non-administrative places and for items about events. Use P1382 if the item falls only partially into the administrative entity.	Museum Tinguely <located in the administrative territorial entity> Basel	-
street address	P6375	Monolingual text	address and street address: full street address where subject is located. Include building number, city/locality, post code, but not country; use also P669 if the street has its own separate item	pavillon Gérard-Morisset <street address> Français : 1, avenue Wolfe-Montcalm, Québec (Québec) G1R 5H3	-
located on street	P669	Item	street: street, road, or square, where the item is located. To add the number, use Property:P670 "house number" as qualifier. Use property P6375 "street address", if there is no item for the street	Louvre Palace <located on street> rue de Rivoli	-
postal code	P281	String	postal code: identifier assigned by postal authorities for the subject area or building	Olympic Museum Lausanne <postal code> 1006	-

Notes:

occupant (P466) enables you to link the buildung to the organization.
Use different from (P1889) to differenciate the bulding from the organization, especially if the items have the same name. Example: Museum Tinguely (Q63058423) refers to the building while Museum Tinguely (Q180904) refers to the memory institution.

Vocabularies and Reference Ontologies

Institution Types

Refer to the "Typology" section for an overview of institution types. The GND, the Library of Congress Authorities, RAMEAU, and probably further vocabularies maintained by other national libraries or similar institutions contain thesauri for various types of heritage institutions. None of the vocabularies reviewed so far seems to have the ambition to provide a comprehensive typology of heritage institutions. On the contrary, they seem to have grown organically, they often lack proper definitions, they are partly country-specific, and the concepts defined in the different vocabularies are not necessarily congruent. They contain however cross-references, which facilitate a mapping among the different vocabularies.

Municipalities and other administrative territorial entities

Municipalities and country sub-divisions should have their own items on Wikidata. This is already the case for many countries, but probably not for all of them. Check out Wikidata:WikiProject Country subdivision and Category:Geographical WikiProjects for information whether a given country has already been covered. If not, ingesting data on all municipalities and other administrative territorial entities should be considered before ingesting data about heritage institutions of a given country.

Mappings to Infobox Templates

The tables below contain overviews of infobox templates related to heritage institutions in the various language versions of Wikipedia. The table is far from being complete; feel free to add information about further infobox templates. Where templates presently already include data from Wikidata, this is indicated by a . Eventually, most data fields used in the templates should also be documented in the "List of Properties" section of this page (at the exception of those relating to buildings); thus the templates can be used as a guide as to which further properties should be included in the inventory of heritage institutions.

Note: There is a mismatch between the ontological approach taken for some of the infoboxes and the one taken in the context of this WikiProject. In fact, some Wikipedia versions, such as the English Wikipedia, originally conceived the infobox templates for museums and libraries as templates for particular types of buildings. In the context of Wikidata it seems reasonable to keep the two classes (buildings and organizations) apart.

See also: Template:Institution – we should also keep an eye on the developments at the interface between Wikimedia Commons and Wikidata, as heritage institutions play an important role as holding institutions of the content at Wikimedia Commons.

To Do List

The following tasks still need to be done (please chime in!):

Split the tables below according to the classes concerned (organizations vs. buildings).
Complement the tables by adding information about more language versions.
Add a "definition" column; make sure that the definitions given for the various language versions in the same row match the common definition; if not, split the row in two or more rows with matching definitions.
Add information about which data fields are required in which languages.
Add Wikidata items for the data fields commonly used in templates.
In cooperation with the various Wikipedia communities: Modify the code of the templates to have them fetch more data directly from Wikidata; document the templates accordingly.
In cooperation with the various Wikipedia communities: Improve the infoboxes on Wikipedia in the light of best practices in other countries; work towards harmonization of the infobox templates across language versions.
In cooperation with the various Wikipedia communities: Promote the systematic use of the infoboxes on Wikipedia.

Museums
