The wikipedia=* tag is used to specify a reference to Wikipedia for a given feature such as a building, bridge, memorial, statue, or road. There are a number of formats for this found in OSM and data users should aim to support the main formats, including those that are discouraged. There is also a project related to a broader collaboration with Wikipedia.

Preferred tagging

Use the format wikipedia=lang:page title linking to the article in Wikipedia for the subject in the primary language (for example wikipedia=fr:Musée du Louvre for the museum in Paris or wikipedia=en:Tower Bridge for the bridge in London).

Please use spaces between words in the title as found the displayed title for the article rather than the underscores and html encoding found in the URL for the Wikipedia article.

A Wikipedia link can be associated with a node, way or relation. For an extensive feature encompasing many individual way, for example a long railway line or river) then it is preferable to include the tag in a relation for the entire feature than to tag every single way, or a subset of the ways.

Methods to be avoided

Do avoid using the Full URL format of the form wikipedia=http://en.wikipedia.org/wiki/St_Paul%27s_Cathedral) as the main Wikipedia URL, underscores and html encoding of special characters which are unnecessary.

Do also always include a language prefix. Use wikipedia=en:St Paul's Cathedral and not wikipedia=St Paul's Cathedral (which includes a language assumption of English or possibly some other language).

Only provide a single Wikipedia link for subject which should be to to the article in the primary language in most circumstances. Data users can access articles in other languages where available using Wikipedia's interlanguage links. The only time that it is appropriate to provide an explicit link to articles in secondary languages is where the subject is included in a article on a broader subject in the secondary language, for example to wikipedia:en=museums in Paris to the English article which provides the best article for the particular museum in France, or wikipedia:fr=places of worship in London which is the best article in French for a particular church in London. In these circumstances then use the format wikipedia:lang=page title for the secondary languages.
