Abstract
Abstract An object based data processing system comprising a plurality of storage domains arranged so that a semantic object in a second storage domain can be accessed by the user of a first storage domain by the creation of a new presentation object in the first storage domain which is linked to the semantic object in the second storage domain.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
59 words
An object based data processing system comprising a plurality of storage domains arranged so that a semantic object in a second storage domain can be accessed by the user of a first storage domain by the creation of a new presentation object in the first storage domain which is linked to the semantic object in the second storage domain.
Claim 2
Dependent Claim
59 words
An object based data processing system comprising a plurality of storage domains arranged so that a semantic object in a second storage domain can be accessed by the user of a first storage domain by the creation of a new presentation object in the first storage domain which is linked to the semantic object in the second storage domain.
Claim 3
Dependent Claim
44 words
A system according to claim 1 configured so that the new presentation object in the first storage domain is created by an existing presentation object in the first storage domain using information received from the semantic object or a parent of the semantic object.
Claim 4
Dependent Claim
76 words
A system according to claim 2 wherein the new presentation object is created as a child of an existing presentation object in the first storage domain which is linked to a parent semantic object in the second storage domain which is a parent of the semantic object and a link is formed between the new presentation object and the semantic object by passing object identification information from the existing presentation object to the new presentation object.
Claim 5
Independent Claim
68 words
A system according to any preceding claim wherein each storage domain comprises a global object for containing objects to be made accessible to the users of other storage domains, a distributed object linked to the global objects of all other storage domains and datacommunication means for communicating with all other storage domains so as to obtain a list of the global objects held on the other storage domains.
Claim 6
Dependent Claim
15 words
A system according to claim 4 wherein the datacommunication means are themselves objects (datacom objects).
Claim 7
Dependent Claim
22 words
A system according to claim 5 wherein the datacom objects continuously communicate amongst themselves to discover which other storage domains are available.
Claim 8
Independent Claim
18 words
A system according to any preceding claim wherein a plurality of the storage domains are on different machines.
Claim 9
Dependent Claim
29 words
A system according to claim 7 when dependent on claim 5 or claim 6 wherein the datacom objects contain a list correlating each storage domain with a corresponding machine.
Claim 10
Dependent Claim
72 words
An object based data processing system comprising a plurality of storage domains, characterized in that each storage domain includes a global object into which the user of the storage domain can place objects to be made accessible to other storage domains; and a distributed object containing the global objects of all other storage domains, the opening of which in any storage domain gives access to the global objects of other storage domains.
Claim 11
Dependent Claim
72 words
An object based data processing system comprising a plurality of storage domains, characterized in that each storage domain includes a global object into which the user of the storage domain can place objects to be made accessible to other storage domains; and a distributed object containing the global objects of all other storage domains, the opening of which in any storage domain gives access to the global objects of other storage domains.
Claim 12
Dependent Claim
35 words
A system according to claim 9 further comprising datacommunication means communicating with all other storage domains to obtain from the other storage domains a list of the global objects held in those other storage domains.
Claim 13
Dependent Claim
14 words
A system according to claim 9 or claim 10 comprising a network of stations.
