  This paper represents an approach to creating global knowledge systems, using
new philosophy and infrastructure of global distributed semantic network (frame
knowledge representation system) based on the space-time database construction.
The main idea of the space-time database environment introduced in the paper is
to bind a document (an information frame, a knowledge) to a special kind of
entity, that we call permanent entity, -- an object without history and
evolution, described by a "point" in the generalized, informational space-time
(not an evolving object in the real space having history). For documents
(information) it means that document content is unchangeable, and documents are
absolutely persistent. This approach leads to new knowledge representation and
retreival techniques. We discuss the way of applying the concept to a global
distributed scientific library and scientific workspace. Some practical aspects
of the work are elaborated by the open IT project at
http://sourceforge.net/projects/gil/.
