History

The library was originally based on the Prototype JavaScript Framework.

OpenLayers was created by MetaCarta after the O'Reilly Where 2.0 conference[3] of June 29–30, 2005,[4] and released as open source software before the Where 2.0 conference of June 13–14, 2006, by MetaCarta Labs. Two other open-source mapping tools released by MetaCarta are FeatureServer and TileCache. Since November 2007, OpenLayers has been an Open Source Geospatial Foundation project.[5]
