One of the aspects of the CAISOR research agenda is the development of a novel approach to the overall software architecture of ordinary (i.e., PC-style) computers, as an alternative to the contemporary practice of distinguishing operating systems, programming languages, database systems, web servers and web clients and their associated languages, and so forth. We believe that it shall be possible to define a much more comprehensive structure that avoids the very large redundancies that exist in the contemporary approach. The Leonardo project addresses this challenge by developing an experimental software system, also called Leonardo, where our approach is being tested and where we expect it to be validated.
The Leordo implementation is a subset of Leonardo that is relatively stable and relatively well documented, and that is used as the platform for a number of application systems, in particular, for the MADMAN system for document management.
