Abstract
Abstract A computer having a file management system and a plurality of objects is presented. The file management allows for the coordination the transfer of data between objects (611-614). A link (615 - 617) with a view may be created between child objects (612 - 614) and a parent object (611) as follows. A user specifies to the child object the data to be displayed and to the parent object a location in which the data is to be displayed. The user causes the file management system to link the child object and the parent object, so that link data structure includes a reference name which identifies the link data structure, a reference to the child object, a reference to the parent object and a data identifier which identifies the data to be transferred. Upon request from the parent object, the child object displays the data in the location specified by the parent object. When the file management system receives the request from the parent object it sends a request for the transfer of the data to the child object. This request includes the location where the data is to be displayed and the data identifier.

Claim 6
Independent Claim
161 words
A method for coordinating display of data from a first object from a plurality of objects, in accordance with the request of a second object in the plurality fo objects in a computer having a file management system and a plurality of objects, characterized by (a) creating in a link reference file, a link entry which includes a reference name which identifies the link entry, a reference to the first object, a reference to the second object and a data identifier which identifies the data to be transferred. (b) sending from the second object to the file management system a firt display request to display data, the first display request including the reference name and the location that the data is to be displayed; and, (c) sending from the file management system to the first object a second display request to display data, the second display request including the location where the data is to be displayed and the data identifier.
Claim 7
Independent Claim
161 words
A method for coordinating display of data from a first object from a plurality of objects, in accordance with the request of a second object in the plurality fo objects in a computer having a file management system and a plurality of objects, characterized by (a) creating in a link reference file, a link entry which includes a reference name which identifies the link entry, a reference to the first object, a reference to the second object and a data identifier which identifies the data to be transferred. (b) sending from the second object to the file management system a firt display request to display data, the first display request including the reference name and the location that the data is to be displayed; and, (c) sending from the file management system to the first object a second display request to display data, the second display request including the location where the data is to be displayed and the data identifier.
Claim 8
Dependent Claim
59 words
A method as in claim 5, characterized in that step (a) includes the substeps of (a1) specifying by a user to the firt object the data to be transferred; (a2) associating by the first object, the data identifier to the data specified by the user; (a3) sending from the second object to the file management system, the reference name.
Claim 9
Dependent Claim
26 words
A method as in claim 5 or 6, characteriz ed in that the first display request does not identify the first object or the data identifier.
Claim 10
Independent Claim
