The Interspace is a system that seeks to unify disparate distributed information resources in one coherent model. The Interspace , as a entity, is a collection of interlinked information spaces where each component space encodes the knowledge of a community or a subject domain. An information space is a collection of interlinked objects. The basic abstraction of this model is a special object called an Information Unit (IU); this serves as the fundamental unit of organization in the Interspace system. Using IUs as a basis, the system also provides a rich set of support for complex inter-operable applications. Standard services include inter-object linking, remote execution, object caching, and support for compound objects (usually referred to as compound documents.)

Additionally, the Interspace system acknowledges the importance of legacy applications and provides support for integrating them into the system in a relatively seamless manner. Ultimately, the Interspace system is an attempt to represent all types data/objects in one flexible, cohesive, and scalable system.
