The ID of the Wikidata item about the feature (for example, Q9141 represents the way Taj Mahal). Like wikipedia=* only entries which are 'about the feature' should be linked. A link from St Paul's Cathedral in London to an entry about St Paul's Cathedral is fine. A link from a bus depot to the company that operates should use operator:wikidata=* instead, link from monument to event that is memorialized should use subject:wikidata=* instead.

For entries with both wikipedia=* and wikidata=* these links should be equivalent, except if Wikidata has a more precise entry, which corresponds better to the OSM object than the Wikipedia article does. In that case the relation between both (The Wikidata entry and its parent wikidata entry, connected to the WP entry) should be described on Wikidata, through a [W]part of or [W]capital of property. Usually there should not be more than one Openstreetmap item with the same Wikidata ID, but in some cases it will be valid mapping.

Semi-automatically finding wikidata IDs

Finding a Wikidata ID

In order to add a Wikidata tag, you first have to find the item ID. An ID always begins with Q, followed by numbers. There are several ways to do so.

Wikidata Search

Search on the Wikidata homepage: Now you can copy the id from that page. Alternatively you can extract the ID from a Wikidata URL:

Wikipedia search

Find a wikipedia article. If the article has a corresponding Wikidata item, you can click the "Wikidata item" button on the side menu. (See the image)

Editor integration


Video guide to easily add Wikidata tags with iD

The default OSM editor on the Web, automatically adds the corresponding wikidata=* key when the wikipedia=* key is updated. Note that you don't need to remove the previous wikipedia=* key.


The Wikipedia plugin for JOSM displays geotagged wikidata=* items or wikipedia=* articles in your area, allowing you to conveniently add them without an explicit searching.

Note that you must review every single edited object. Otherwise it is an automated edit and you must follow Automated Edits code of conduct.

Adding missing items to Wikidata

Wikidata is a separate project, and a sister project of Wikipedia, which is freely editable in a similar fashion to OSM and Wikipedia. If an item does not exist in Wikidata itself, you can create it; but please read Wikidata's notability guidelines first.


Wikidata values are clickable on the OSM main site, and they link to the corresponding Wikidata item. Example: way 369161987

OpenStreetMap's River Sherbourne relation, [W]seen in Wikidata using the 'osm.js' user script

From Wikidata's side, it is possible to automatically visualize whether a Wikidata item is being linked to and from OSM, by installing a script on your common.js page.

Secondary Wikidata links

See also Secondary Wikidata links and Secondary Wikimedia Commons links

You may tag secondary attributes of a feature by preceding the wikidata=* key with the name of the attribute, separated by a colon (:). The value of such a key would be the same as the normal wikidata=* key but referring to the appropriate Wikidata entry.

For example, brand:wikidata=Q38076 on a McDonald's fast food unit (but don't forget to also tag brand=McDonald's, because the former tag doesn't replace the latter).

Common secondary Wikidata tags:

Operator (not franchise) of a restaurant, shop, bank, or some other customer service or office. Entity type must be [W]organization operator:wikidata=* operator:wikidata=Q5703224
Network of public transit routes. network:wikidata=* network:wikidata=Q614819
Used for various stores or franchise brands. e.g. [W]McDonald's for a fast-food franchise outlet. brand:wikidata=* brand:wikidata=Q38076
The architect (or architectural firm) of a building. It should be an instance of [W]human or [W]company. architect:wikidata=* architect:wikidata=Q374276
The artist/maker of statue or other artwork or memorial. It should be an instance of [W]human (if the artwork was not made by a human, use the appropriate info. e.g [W]elephant). artist:wikidata=* artist:wikidata=Q5582
The species of a plant or an animal. It should be an [W]instance of species:wikidata=* species:wikidata=Q15978631
The genus of a plant or an animal, should be an [W]instance of. sometimes it is not possible to specify exact species. genus:wikidata=* genus:wikidata=Q171283
The taxon of a plant or an animal, may be either species or genus. taxon:wikidata=* taxon:wikidata=Q171283
The subject of a statue, artwork, or memorial (a person, event, geographical feature, ...). In some rare cases where the subject is plural, values will be separated by a semicolon. subject:wikidata=* subject:wikidata=Q23
The person, event, geographical feature or other subject that an entity (e.g. a street, airport, or building) is named after. For an old_name=*, use old_name:etymology:wikidata=* name:etymology:wikidata=* name:etymology:wikidata=Q1394
The specific flag hoisted on a man_made=flagpole. The value should be an [W]instance of or a [W]subclass of [W]flag flag:wikidata=* flag:wikidata=Q172446
The tomb or burial site of a famous individual. The value should be an [W]instance of a[W]human (or possibly an [W]instance of or [W]subclass of an [W]individual animal.

In many cases tombs are treated as special type of memorial with subject:wikidata=* being used.

buried:wikidata=* buried:wikidata=Q172446
The monarch's initials or symbol. Mostly seen on royal mail postal boxes. royal_cypher:wikidata=* royal_cypher:wikidata=Q114242600
The manufacturer of a manufactured object. manufacturer:wikidata=* manufacturer:wikidata=Q7992391
The model designation of a manufactured object. model:wikidata=* model:wikidata=Q3993741
The building itself. Used when a POI is tagged on a building way, but they both have wikidata items.

Note that it is violation of One feature, one OSM element and it is preferable to map POI and building as separate objects.

building:wikidata=* building:wikidata=Q28404263
!Note: this is not a exhaustive list of all *:wikidata tags. For a list of all secondary attributes currently being tagged with this key, see taginfo

Occasionally, a feature may have one or more secondary links, but no primary link. For example, a memorial depicting a famous event may have only a secondary subject:wikidata=* link. Monuments, memorials, statues and similar features should have wikidata=* only if they have their own Wikidata item. The same applies to chain stores.

What not to tag

Dialog-warning-orange.svg Instances of the following Wikidata items (and of any subclasses of the listed items) should be avoided in the wikidata=* tag:

These types normally don't occur as OSM objects and since the main wikidata=* tag is for Wikidata items that are equivalent to OSM objects, Wikidata items of these types are normally tagging errors. However, for secondary wikidata tags these classes are fine.*[W]human (Q5) (typically subject:wikidata=* should be used for artwork depicting humans or buried:wikidata=* for burial sites for the specific individual)

It may be better to store certain data only on Wikidata. For example, instead of using name:etymology:wikipedia=* or name:etymology:wikidata=* one may follow the Wikidata link and use Wikidata's [W]named after

Bugs and workarounds

Issue 6789 In the ID editor after adding the Wikidata item, the names will be locked in the fields section with the message: The "Name" field is locked because there is a Wikidata tag. You can delete it or edit the tags in the "Tags" section. However, it is still possible to edit names using the tags section.
