Data navigator interface with navigation as a function of draggable elements and drop targets

Claim 2

A hypertext browser which displays hypertext pages referencing other hypertext pages comprising: means, within the hypertext browser, for indicating one or more draggable element of a page being viewed; means for displaying one or more drop target on a user display, either within a browser window or outside the browser window; means for detecting an event when a user selects a selected draggable element and drops the selected draggable element over a selected drop target; and means, coupled to the means for detecting, for generating a message which is a function of the selected draggable element and the selected drop target wherein the message is formatted to resolve to a referenceto a new hypertext page to be generated and viewed in response to the event.

Claim 3

The hypertext browser of claim 1, wherein objects in an object model which have at least one input are objects which are potential drop targets, objects which have at least one output are potential draggable elements, and objects which have at least one input and at least one output are potential draggable elements and potential drop targets.

Claim 4

The hypertext browser of claim 1, further comprising means for navigating to a new location in a hypertext document or hypertext server web based on the generated message.

Claim 5

The hypertext browser of claim 1, wherein the draggable element is a text string on the page being viewed.

Claim 6

A hypertext system for displaying hypertext pages comprising: a hypertext browser, comprising: means, within the hypertext browser, for indicating one or more draggable element of a page being viewed; means for displaying one or more drop target on a user display, either within a browser window or outside the browser window; means for detecting an event when a user selects a selected draggable element and drops the selected draggable element over a selected drop target; and means, coupled to the means for detecting, for sending a message to a hypertext server in response to the events wherein the message references the selected draggable element and the selected drop target; and the hypertext server comprising: means for receiving messages from hypertext browsers; a matrix of class relations having a cell for each combination of a draggable element reference and a drop target reference; means, coupled to the means for receiving and the matrix, for identifying a cell in the matrix for the selected draggable element and the selected drop target indicated by a received message; and means, coupled to the means for identifying, for performing an action which is a function of contents of the cell.

Claim 7

A hypertext system for displaying hypertext pages comprising: a hypertext browser, comprising: means, within the hypertext browser, for indicating one or more draggable element of a page being viewed; means for displaying one or more drop target on a user display, either within a browser window or outside the browser window; means for detecting an event when a user selects a selected draggable element and drops the selected draggable element over a selected drop target; and means, coupled to the means for detecting, for sending a message to a hypertext server in response to the events wherein the message references the selected draggable element and the selected drop target; and the hypertext server comprising: means for receiving messages from hypertext browsers; a matrix of class relations having a cell for each combination of a draggable element reference and a drop target reference; means, coupled to the means for receiving and the matrix, for identifying a cell in the matrix for the selected draggable element and the selected drop target indicated by a received message; and means, coupled to the means for identifying, for performing an action which is a function of contents of the cell.

Claim 8

The hypertext system of claim 5, wherein the action performed by the hypertext server is an action of returning a hypertext page to the hypertext browser.

Claim 9

The apparatus of claim 5, further comprising an object model server for providing a class relation for the selected draggable element and the selected drop target where the cell in the matrix at the hypertext server indicates that the relation between the selected draggable element and the selected drop target is not stored local to the hypertext server.

Claim 10

The apparatus of claim 5, further comprising an object reference server and means for querying the object reference server to obtain an object-to-object relationship between the draggable element and the selected drop target when either the draggable element or the selected drop target are not found in the class relation matrix.

Claim 13

The method of claim 9, wherein the step of dragging the draggable element is a step of dragging a text phrase.

Claim 14

The method of claim 9, further comprising the steps of: f) displaying at least one subsequent draggable element on the subsequent hypertext page; and g) repeating steps b) through e) in response to user input.

Claim 15

The method of claim 9, wherein the step of generating a reference comprises the steps of: locating a cell in a matrix where the cell is pointed to by the draggable element and the drop target; generating a reference from the contents of the located cell; and when the contents of the located cell includes an external reference, resolving the external reference.
