aitools.org is the home of Program D and xAIML technologies. It grew out of efforts that originated with the creation of the ALICE AI Foundation. At the inception of the foundation, two primary goals were to publish a formal specification of AIML, and a working reference implementation of the same. The former goal was achieved by Noel Bush, who authored the AIML specification in 2001 under the auspices of the Foundation's Architecture Committee. The reference implementation goal was initially addressed by Pedro Colla, Thomas Ringate and Kim Sullivan, based on a code base bequeathed by Jon Baer; this work was taken up by Noel Bush in 2001. Program D took on a life of its own and became the de facto reference implementation of AIML, even after the foundation became a commercial concern. aitools.org was created to preserve the FOSS (free and open source) nature of the original AIML project, and to provide a home for Program D and associated technologies. Up through the present, it is supported by Noel Bush and Nika Dubrovsky, and survives solely upon the basis of this support and occasional contributions of assistance.
