A distributed object based system (10) comprising primary (P) and secondary (S) objects with provision for containership links between primary objects and objects which they contain and for weak links between objects. A weak link enables a user indirectly to insert an object (or other item, e.g., text) into a target object via an intermediate object weakly linked to the target object.

Object based system comprising weak links

Object based computer system which has objects and object parts which are either (a) semantic, relating to stored data, or (b) presentation, relating to presentation of the semantic objects to the user. Multiple presentation objects, or viewers, can be linked to a particular semantic object so that an intelligible user's model of the system results. Representation objects provide particular forms of presentation of data of the semantic objects and may be linked so that alternative and multiple presentations of the data of a semantic object are possible.

Selective user coupling for shared object oriented computer system

A distributed object based system includes primary and secondary objects. Primary objects can sustain containership links to other objects in the same storage domain and weak links can exist between objects in different storage domains.

Object based system comprising user interface permitting manipulation of

An object based computer system has viewers which may be directed around the object world of the system between semantic objects. The system includes a sequence object that has a path list specifying a path around a sequence of semantic objects of system. Each viewer can be linked to the sequence object to access the path list held by the latter, thereby enabling the viewer to follow the corresponding sequence of semantic objects, viewing each in turn.
