I guess no web site would be complete without a list of links - so here you are :-)
These are projects which are also working towards (or have achieved) a free implentation of
a MultiValue DBMS, although not Open Source.
- Winter is a Multivalue Database designed
around a Bytecode interpreter. The interpreter is being designed so that it will be
able to emulate any "flavor" of MVDB. Winter runs on either Intel or PPC based Linux
- Bart is MultiValue Database
Virtual Machine for Windows.
