 The purpose of KMS was to let many users collaborate in creating and sharing information within large, shared hypertext, and from the very beginning, the system was designed as a true multi-user system.As a spatial hypermedia system, KMS was intended to represent all forms of explicit 'knowledge artifacts' such as presentations, documents, databases, and software programs, as well as common forms of electronic communication (electronic mail, community bulletin boards, blogs).The central element in the KMS data model is that of screen-sized pages (called "frames") interconnected by links.
