Legally, OSMF is registered at Companies House in London as a company limited by guarantee (not by shares). The articles provide that the company's property cannot be distributed to its members. It operates under the law of England and Wales.

The Foundation was established to: [ citation needed ]

  • To be a custodian for the servers and services necessary to host the OpenStreetMap project. Specifically the foundation is the custodian of the servers located at UCL, Bytemark, Equinix and around 50 tile cache servers globally. The Foundation also owns and manages the domain name.
  • To afford some degree of protection from copyright and liability suits.
  • To provide a vehicle for fundraising to support the project.

The purposes of the Foundation stated in its legally registered constitution (the 'articles of association') are:

(a) encouraging the growth, development and distribution of free geospatial data; and
(b) providing geospatial data for anyone to use and share.[1]

The directors are under a legal duty to pursue these (and only these) purposes. See United Kingdom Companies Act 2006, section 172.


You do not have to be a member in order to use or contribute to OpenStreetMap.

Members have a vote as part of the sovereign body of the Foundation. Among other things, the members have the power to:

  • appoint and dismiss directors
  • require directors to do or not do something (but the power is not retrospective)
  • require an audit of the Foundation's accounts
  • call a general meeting of members
  • change the Articles of Association
  • stand for election to the board themselves

(Various different quora or voting majorities are required for these.)

Individuals can join the Foundation by paying a fee of £15. Regular mappers and people active in other OSM support work can apply for 'Active Contributor Membership', which, if granted, will allow a full waiver of the membership fee.

Companies/organisations can also apply for Corporate membership.

Membership includes a discount for some events organised by OSMF (such as the annual State of the Map conference).

A members' email list is available to members to communicate with other members. (Note that anyone, even non-members, can read the discussion.)

The members of the Foundation form the sovereign body of the Foundation. Their relations with each other are regulated by the Articles of Association.

Articles of association

The Memorandum of Association and Articles of Association for the OpenStreetMap Foundation are available from the Foundation website.

The AoAs have been revised three times since 2007:

General meetings

A 'general meeting' is a meeting which all members may attend. Votes passed at a general meeting are usually binding, and must be put into effect by the directors.

Typically there is a general meeting once per year, in close proximity to the board elections. Attendance at a general meeting is not required to vote on the matters considered at that meeting: since 2014 voting is via an on-line voting service with email invitation for all members. Prior to 2014 voting was by paper ballot in person at the AGM, or email by proxy. Join

The next general meeting is in December 2020: Foundation/AGM20

Information on past meetings can be found on the OSMF website.

Board of directors

The Foundation (as a UK company) is a legal person, but a person that cannot act for itself. The basic legal position is that the Foundation can act only through its directors.

Members are appointed by election of members of OSMF foundation, and they meet regularly.

Information on upcoming and past meetings can be found on the OSMF website.

Appointment of directors

Directors are appointed by election through an electronic voting system, usually around December.


Directors' primary legal duty is to manage the Foundation in the way that they believe, in good faith, achieves the purposes given in clause 2 of the Articles of Association. This and their other duties are set out principally in Chapter 2 of the (UK) Companies Act 2006. They have other responsibilities set out in other UK legislation and in the English common law.

Scope of the OSMF board in Mission statement list what board is supposed to be doing.

Monthly Board Meetings documentation includes list of decisions taken by OSMF board. It includes for example

Foundation wiki has also OSMF updates and Annual General Meeting typically includes Annual Reports, like this one for 2020.


Formal meetings of the board are normally held monthly and the Board Meeting Minutes are published on the foundation website.
