The website of the State Commission for Lithuanian Language (VLKK) “World Site Names” collects merged names of objects of the world. The data base consists of a dictionary prepared and published by the Centre for Science and Encyclopaedia Publishing (MELC). Data have been collected since 2014 and are up-to-date. The data includes an object identifier that combines its names in the original and Lithuanian languages, names with and without accents, an indication of whether the name is merged, the object type, country, continent, location to indicate the location of the object and the number of searches, the earliest and most recent dates.
