This document discusses two open-source e-learning platforms developed in Luxembourg: AnaXagora and OpenMCMS. AnaXagora was created through a collaborative process between the CRPHT and other partners. It was developed from the open-source platform Ganesha, adding new functionality. OpenMCMS was created by the CVCE to support their European Navigator knowledge base, providing content management and multimedia capabilities. Both platforms use open-source philosophies and licenses to promote sharing and dissemination of knowledge.
