GNOWSYS is an acronym for "Gnowledge Networking and Organizing SYStem." It is a web based object oriented database server with each object provided by an unique URL. GNOWSYS is a tool to construct and store persistently a Gnowledge Base (GB). The GB consists of the following three groups of constructor classes (system and temporal classes under development):

PredicateGroup: relationType, relation, functionType, function

Object Group: metaType, class, object (with provision to have classes and objects of declarative, procedural, encapsulated, temporal etc.)

Structure Group: systemType, system, flowType, flow, processType, process

GNOWSYS indexes data and metadata of objects in a catalogue for faster queries. Optionally, data can remain anywhere on the Internet (only the metadata stays in the database). Surrogates of procedures (classes, functions, and system calls) can also be installed in the database as special objects. These procedures execute as web services, so users can design applications without writing program in any programming language by specifying the semantics of a program and mapping the elements of the program to the surrogates of procedures is sufficient for GNOWSYS to test the application design.
