The ARIADNE vision and aims have been conceived around 1995, and have been initially funded by an EU project that was called "ARIADNE: Alliance of Remote Instructional Authoring and Distribution Networks for Europe"  (1996-1998). From those days, the ARIADNE infrastructure has been further developed and evolved, both by the contributions of its members but also with significant funding from the European Commission and other sources. In this section we identify some core projects that contributed directly or indirectly to the development, maintenance and evolution of ARIADNE all these years.
