Abstract

In one form, a method, for creating multiple segments of source information for presentation on a device having a limited size display screen, includes generating a first derivative file describing first presentation material. The derivative file is derived from a first copy of a master style sheet file. The master style sheet specifies a style of displaying the source information. The source information includes a plurality of attributes, of which a first set of attributes are included in the first derivative style sheet file. A second derivative file describing second presentation material is derived from a second copy of the master style sheet file. A second set of attributes included in the source information are included in the second derivative file. The first presentation and second presentation materials are generated responsive to the source information and the respective first and second derivative files.

generating first presentation material in response to the source information and the first derivative style sheet file; and

generating second presentation material in response to the source information and the second derivative style sheet file.

2. The method of claim 1, wherein the source information specified by the master style sheet exceeds an amount of information capable of being displayed by the device in a single view, the source information comprising a first segment of information associated with the first set of attributes and a second segment of information associated with the second set of attributes, and wherein the first presentation material is for generating a first view of the first segment on the device and the second presentation material is for generating a second view of the second segment on the device, the device being capable of concurrently displaying, in the first view, all of the first segment of information and concurrently displaying, in the second view, all of the second segment of information.

3. The method of claim 1, wherein generating the first derivative style sheet comprises deleting at least a first attribute from the plurality of attributes, the at least first attribute being included in the second set of attributes.

4. The method of claim 1, wherein generating the first derivative style sheet comprises adding a link attribute referring to the second derivative style sheet, the link attribute enabling navigation between a first segment of information associated with the first set of attributes and a second segment of information associated with the second set of attributes.

5. The method of claim 1, wherein generating the second derivative style sheet comprises deleting at least a second attribute from the plurality of attributes, the at least second attribute being included the first set of attributes.

6. The method of claim 1, wherein generating the second derivative style sheet comprises adding a link attribute referring to the first derivative style sheet, the link attribute enabling navigation between the second segment of information associated with the second set of attributes and the second segment of information associated with the first set of attributes.

7. The method of claim 1, wherein the first set of attributes and the second set of attributes have at least one common attribute.

8. The method of claim 1, wherein at least one of the source information attributes is excluded from the first set of attributes and included in the second set of attributes, and at least one of the source information attributes is excluded from the second set of attributes and included in the first set of attributes.
