==OpenGEM==
'''OpenGEM''' is a non-[[computer multitasking|multitasking]] [[16-bit]] [[graphical user interface]] (GUI) for [[DOS]]. It is an extended distribution of FreeGEM that includes features of the original [[Digital Research]] [[GEM (desktop environment)|GEM]].

OpenGEM is intended to provide a simple to install and use GUI system and windowing framework for the [[FreeDOS]] operating system.

Caldera Thin Clients (later known as [[Lineo]]), who owned the source code to GEM through [[Caldera, Inc.|Caldera]]'s purchase of the remaining Digital Research assets from [[Novell]] on 23 July 1996,<ref name="Leon_1996_Caldera"/> released the source to GEM under the terms of [[GNU General Public License|GPL-2.0-only]] in April 1999.<ref name="Jemmett_1999"/> OpenGEM was developed by Shane Martin Coughlan in collaboration with the FreeGEM Developer team, and is [[free software]] released under the terms of the [[GNU General Public License|GPL-2.0-only]]. OpenGEM versions 3 through 6 are hosted on SourceForge and on the FreeDOS website.

OpenGEM has not been actively developed since 2008 but is feature-complete as a basic GUI and includes a full SDK for future third-party development or extension.
