museum is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet used exclusively by museums, museum associations, and individual members of the museum profession, as these groups are defined by the International Council of Museums (ICOM).

In joint action with the J. Paul Getty Trust, ICOM established the Museum Domain Management Association (MuseDoma), headed by Cary Karp, for the purpose of submitting an application to ICANN for the creation of the new generic top-level domain (gTLD), and to operate a registry. The museum domain was entered into the DNS root on 20 October 2001, and was the first sponsored top-level domain to be instituted through ICANN's action.

The purpose of this domain is to reserve a segment of the DNS name space reserved for the use of museums; a name space whose conventions are defined by the museum community. The museum TLD grants users a quick and intuitive way to verify the authenticity of a museum site. Conversely, since it is a type of formal third-party certification, museums using this name space obtain a way to assure visitors of the site's validity.

A museum (/mjuˈziːəm/; myoo-zee-um) is an institution that cares for (conserves) a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance and makes them available for public viewing through exhibits that may be permanent or temporary. Most large museums are located in major cities throughout the world and more local ones exist in smaller cities, towns and even the countryside. Museums have varying aims, ranging from serving researchers and specialists to serving the general public. The goal of serving researchers is increasingly shifting to serving the general public.

Some of the most attended museums include the Louvre in Paris, the National Museum of China in Beijing, the Smithsonian Institution in Washington, D.C., the British Museum in London, the National Gallery in London and The Metropolitan Museum of Art in New York City. There are many types of museums, including art museums, natural history museums, science museums, war museums and children's museums.

Museum is a subway station on the Yonge–University line in Toronto, Ontario, Canada. It opened in 1963 and is located under Queen's Park at Charles Street West, beside the Royal Ontario Museum after which it is named.

Structure

The station structure was created in the middle of the road using cut and cover, while immediately south of the station the line goes into a bored tunnel to run under Queen’s Park, passing east of the Ontario Legislative Building to reach Queen's Park station. The concourse is located under the roadway, one level above the north end of a centre platform, with entrances from either side of the road. There are two stairways on the west side adjacent to the southern end of the Royal Ontario Museum and two on the east, just south of Charles Street. Pedestrians are encouraged to use the station as a pedestrian underpass to cross Queen's Park, a wide and busy thoroughfare without a centre median. This station does not have an elevator and is not wheelchair accessible.
