Abstract

A computer user interface includes a mechanism for graphically representing and displaying user-definable objects of multiple types. The object types that can be represented include data records, not limited to a particular kind of data, and agents. An agent processes information automatically on behalf of the user. Another mechanism allows a user to define objects, for example by using a template. These two mechanisms act together to allow each object to be displayed to the user and acted upon by the user in a uniform way regardless of type. For example, templates for defining objects allow a specification to be input by a user defining processing that can be performed by an agent.

Claims

1. A computer user interface, comprising:

means for graphically representing objects that collectively are instances of a plurality of object types, wherein an object has a plurality of fields of which at least one field may contain information of any type; and

means for creating and editing object types, and for creating, editing and displaying each instance of an object type using a template;

wherein the means for graphically representing objects, and the means for creating and editing each object type and creating, editing and displaying each instance, present each object to and permit action upon and editing of each object by a user in a substantially uniform way, regardless of type, and

wherein the means for graphically representing objects includes means for displaying a summary of a collection of objects showing one or more fields selected by a user from each of the objects.

2. A computer user interface according to claim 1, further comprising:

means for permitting objects to be defined hierarchically by the user.

3. A computer user interface according to claim 2, wherein the graphical display of the link includes at least one of a symbol for the second object, and a template associated with the second object.

4. A computer user interface according to claim 1, wherein each object type has a set of actions that can be performed upon instances of the object type, and the objects are arranged in a hierarchy of increasingly specialized types, with each object type inheriting fields and actions from any parent thereof.

5. A computer user interface according to claim 4, wherein a rule is one of the object types.

6. A computer user interface according to claim 4, wherein a folder is one of the object types.

7. A computer user interface according to claim 4, wherein a folder is one of the object types and a rule is another of the object types.

8. A computer user interface according to claim 1, wherein a first object may contain, as part of a value of one of the fields, a link to a second object, and wherein the means for graphically representing the first object graphically displays the link.

9. A computer user interface according to claim 1, wherein a folder is one of the object types.

10. A computer user interface according to claim 1, wherein a folder is one of the object types and a rule is another of the object types.

11. The computer user interface of claim 1, wherein the means for creating and editing object types includes means for adding fields to an object type.

12. The computer user interface of claim 1, wherein the summary is a table view.

13. The computer user interface of claim 1, wherein the summary is a graphical view.

14. A computer user interface, comprising:

means for graphically representing a collection of objects of more than one type in a selected one of formats, wherein one format is a table and another format is a graphical view wherein the structure of the graphical view shows relationships among objects in the collection, wherein an object has a plurality of fields, wherein at least one field may contain information of any type;

means for creating and editing object types and instances of object types using a template; and

means for permitting the user to customize the formats utilized by the means for graphically representing the collection of objects, according to one or more selected fields defined for the object types.

15. A computer user interface according to claim 14, wherein each object has a set of fields and a first object may contain, as part of the value of one of its fields a link to a second object.

16. A computer user interface according to claim 15, wherein the graphical view is a node-arc graph.

17. A computer user interface according to claim 14, wherein the graphical view is a node-arc graph.

18. A computer user interface according to claim 14, wherein a folder is one of the types of objects in the collection and the collection is a folder.

19. An interface according to claim 14, wherein the means for graphically representing includes means for permitting any of the formats to be applied to any collection of objects.

20. An interface according to claim 19, wherein the graphical view is a node-arc graph.

21. An interface according to claim 19, wherein the graphical view is a calendar view.

22. An interface according to claim 14, wherein the graphical view is a calendar view.

23. The computer user interface of claim 14, wherein the means for creating and editing object types includes means for adding fields to an object type.

24. A computer user interface comprising:

means for easily creating and editing object types with different fields, wherein information in at least one of the fields of each object may be of any type;

means for easily creating and editing instances of objects of the defined object types; and

means for easily creating different user-tailorable summary views of collections of the instances of objects, wherein a view is defined by one or more selected fields defined for the object types.

25. The computer system of claim 24, further comprising:

means for easily defining links between instances of objects; and

means for providing traversal of links.

26. The computer system of claim 25, wherein links may be active links in fields of objects;

and

wherein the means for creating views may create views of objects generated by following active links in the fields used to generate the view.

27. The computer system of claim 26, further comprising:

means for easily defining agents for performing functions on instances of objects.

28. The computer system of claim 27, wherein agents are defined as objects having fields including functions to be performed, and wherein the means for creating views allows a view to be created based on fields of agent objects.

29. The computer system of claim 25, further comprising:

means for defining agents for performing functions on instances of objects.

30. The computer system of claim 29, wherein agents are defined as objects having fields including functions to be performed, and wherein the means for creating views allows a view to be created based on fields of agent objects.

31. The computer system of claim 24, further comprising:

means for defining agents for performing functions on instances of objects.

32. The computer system of claim 31, wherein agents are defined as objects having fields including functions to be performed, and wherein the means for creating views allows a view to be created based on fields of agent objects.

33. The computer user interface of claim 24, wherein the means for easily creating and editing object types includes means for adding fields to an object type.

34. An object-oriented computer user interface system, comprising:

a generic semi-structured object type comprising;

a collection of fields, wherein at least one field may contain information which may be of any type;

a create subclass method for permitting a user to create a new subclass of an object type;

a create instance method for permitting a user to create a new instance of an object type;

an edit method for permitting a user to edit the object type; and

a display method permitting a user to select fields of an object type for displaying a summary of a collection of objects including objects of at least the object type, thereby providing user-tailorable summary views.

35. The object-oriented computer user interface system of claim 34, wherein the generic semi-structured object type further comprises:

a field edit method for permitting a user to add a field to the collection of fields of an object type.
