Abstract

Abstract A method of transforming a first editable form of a document prepared by an interactive text processing system into a second and incompatible editable form for use in another interactive or batch text processing system through the use of a transform mechanism is described. A significant step of this method requires the identification of a limited number of key state variables, whose values collectively identify the necessary state information for transforming the first document form to the second. After the key state variables have been identified, the actual number of combinations thereof is determined. For each first document form input item encountered by the transform mechanism, and for each combination of key state variables in which that input item can be encountered, one or more output items for the second document form is explicitly defined as the transform thereof. In addition, the state of the transform mechanism after each such transform has occurred, must also be specified. The described method is also to resolve the actual state that exists at the start of each document. It is also adapted to handle sub-documents, such as margin text, existing within a document to be transformed.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 161 words
A method of transforming a source document, cast in a first editable form which includes a plurality of input items therein, to a target document of a second editable form which includes output items compatible therewith, said method comprising the steps of: (a) determining a set of key state variables, from amongst all possible key state variables, that refers to and collectively identifies the status of said source document as represented by its data stream at any given point in said transformation; (b) determining the actual number of possible key state combinations that can occur in any possible transformation; (c) defining for each of said possible key states combination, in combination with each of said input items, and explicit set of output items compatible with said second editable document form to be placed in said second document; and (d) defining, after each explicit set of output items has been placed in said second document, the next state of said source document.
Claim 2
Independent Claim 161 words
A method of transforming a source document, cast in a first editable form which includes a plurality of input items therein, to a target document of a second editable form which includes output items compatible therewith, said method comprising the steps of: (a) determining a set of key state variables, from amongst all possible key state variables, that refers to and collectively identifies the status of said source document as represented by its data stream at any given point in said transformation; (b) determining the actual number of possible key state combinations that can occur in any possible transformation; (c) defining for each of said possible key states combination, in combination with each of said input items, and explicit set of output items compatible with said second editable document form to be placed in said second document; and (d) defining, after each explicit set of output items has been placed in said second document, the next state of said source document.
Claim 3
Dependent Claim 27 words
The method according to claim 1 which comprises the additional step of determining the actual starting state of said source document prior to enabling said transformation thereof.
Claim 4
Dependent Claim 33 words
The method according to claim 1 which comprises the additional step of determining the the presence of sub-documents within said source document and thereafter preserving the same for use after transformation has occurred.
Claim 5
Dependent Claim 31 words
The method according to claim 1 which comprises the additional step of limiting the number of possible combinations of said key state variables to which there will be a transformation reaction.
Claim 6
Dependent Claim 31 words
The method according to claim 4 which comprises the additional step of determining an ordered set of implications concerning the relationships among the key state variables in any permissible set thereof.
