It provides an API for building rich web-based geographic applications similar to Google Maps and Bing Maps.
It is open-source, provided under the 2-clause BSD License.<ref>{{cite web | url=https://www.openlayers.org/ | title=OpenLayers: Home | access-date=7 December 2012}}</ref>
==Features== OpenLayers supports GeoRSS, KML (Keyhole Markup Language), Geography Markup Language (GML), GeoJSON and map data from any source using OGC-standards as Web Map Service (WMS) or Web Feature Service (WFS).
== History == The library was originally based on the Prototype JavaScript Framework.
OpenLayers was created by MetaCarta after the O'Reilly Where 2.0 conference<ref>{{cite web|url=http://trac.openlayers.org/wiki/History|archive-url=https://web.archive.org/web/20071018120601/http://trac.openlayers.org/wiki/History|url-status=dead|archive-date=2007-10-18|title=History – OpenLayers 2}}</ref> of June 29–30, 2005,<ref>{{cite web|url=http://conferences.oreillynet.com/archive.csp|title=Conferences Header - ML Redesign}}</ref> and released as open source software before the Where 2.0 conference of June 13–14, 2006, by [https://web.archive.org/web/20070813180053/http://labs.metacarta.com/ 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.<ref>{{cite web|url=http://www.osgeo.org/node/462|title=OpenLayers Achève sa Phase d'Incubation - OSGeo.org|access-date=2008-07-01|archive-url=https://web.archive.org/web/20090331064151/http://www.osgeo.org/node/462|archive-date=2009-03-31|url-status=dead}}</ref>
