History
OpenLayers was created by MetaCarta after the O'Reilly Where 2.0 conference[1] on June 29-30, 2005,[2] and released as open source software before the Where 2.0 conference on June 13-14, 2006, by MetaCarta Labs. MetaCarta maintains an active role in supporting and managing the project. Two other open source mapping tools released by MetaCarta are FeatureServer and TileCache. Since November 2007 OpenLayers is an Open Source Geospatial Foundation project[3].
