WikiProject Belgium/Conventions/EU institutions and bodies

From OpenStreetMap Wiki
Jump to navigation Jump to search

EU institutions and bodies shall be tagged folllowing a convention to help OSM users to discover the EU institutions, expose them via the various name search APIs, and to generate easily maps of EU institutions and bodies. While the EU has buildings in many countries of the world, the majority is situated in Brussels. To begin with, the mapping efforts focuses on Brussels and therefore this page belongs to the WikiProject Belgium. A later move is not excluded.

For an in-depth overview of the European Union (EU), consider the Wikipedia Page of the EU. In short, the EU is an international governmental organisation consisting of a number of institutions with executive, legislative and judiciary functions, and a number of other bodies tasked with e.g. implementing specific policies.


A convention to tag EU institutions and bodies has a number of advantages:

  • People can easily geolocate the institutions. The EU institutions welcome many international guests and OSM can help those to find their way. For this, it is important that the locations can be found by the common names of the institutions and bodies. Also EU building names should be integrated in OSM.
  • Data of EU institutions and bodies can be automatically exported to create custom maps of EU institutions and bodies. Learn here more about querying EU countries using overpass turbo.


  • There is no existing convention on how to tag international governmental organisations (intergovernmental organisations) in OSM.
  • The EU promotes diversity also in languages and most of its offices have names in various languages. On top of it, acronyms of institutions/bodies and buildings are used, which may again vary from one language to another.


The following proposals stem from existing tagging practices, analogies drawn from similar objects, and extrapolation of descriptions of existing tags. Please use the discussion page to provide feedback.

Prefer to tag EU offices as POIs and not as buildings, because often buildings can host more than one EU office or host also other shops/companies.

Buildings comprising an EU office

No EU specific tags if not the entire building is operated by the EU.

If the entire building is managed by the EU, than consider the following tags:

Key Example Value Explanation
operator=* European Parliament Give the name of the operating body, e.g. the European Parliament.
operator:wikidata=* Q8889 Give the Wikidata key of the operating body. You can find out the number from the Wikipedia page, which has a link to the wikidata object in the left panel.
short_name=* MTS The short name of the building according to the EU, so that the building can be found by its name.

POIs for EU offices

POIs for EU offices should be tagged as office=government.

Only the EU office-specific tags are listed here. Please also add address tags, accessibility tags and so on.

Key Example Value Explanation
name=* EDPS The short name of the office, e.g. EDPS for European Data Protection Supervisor
name:en=* European Data Protection Supervisor The long name of the office. Please try to add names in all EU languages. Often, they can be found on Wikidata or Wikipedia.
addr:housename=* MTS The short name of the building in which the office is located.
office=* government All EU offices are primarily governmental offices.
government=* ministry Parliament offices should be generally tagged as legislative and Commission offices, such as a "Directorate General", as ministry. Please check the documentation of government=* to find the most appropriate function.
country=* EU This is the most important tag. Similar to its use alongside Tag:amenity=embassy, it qualifies this office as belonging to the European Union. country=* shall always refer to a country code  ISO 3166-1 alpha-2, but such a code was reserved for the EU despite not being a country. Do not confuse this tag with the address tag addr:country=*.
