is a portable distributed object-oriented database designed to support the maintenance and sharing of knowledge bases. Unlike other object-oriented databases, FramerD is optimized for the sort of pointer-intensive data structures used by semantic networks, frame systems, and many intelligent agent applications. FramerD databases readily include millions of searchable frames and may be distributed over multiple networked machines. FramerD includes an extensive scripting language based on Scheme with special support for web-based interfaces.
FramerD is implemented in ANSI C and has been compiled for a wide range of platforms, including many varieties of Unix and WIn32. In addition, experimental Java and Lisp libraries exist for accessing FramerD databases and services. [via e7l3.com]
