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.

Claims

1. A method for creating multiple segments of information for presentation on a device having a limited size display screen, the method comprising:

generating a first derivative style sheet file from a first copy of a master style sheet file, wherein the master style sheet file specifies, as a set of attributes, a certain portion of source information for presenting on a certain display screen, wherein the set of attributes exceeds an amount of information capable of being displayed by the limited size display screen in a single view, and wherein generating the first derivative style sheet file includes;

deleting ones of the attributes from the first copy of the master style sheet file, so that the first copy of the master style sheet file has a first subset of the attributes specifying a first segment of the source information;

generating at least a second derivative style sheet file from at least a second copy of the master style sheet file, including;

deleting ones of the attributes from the at least second copy of the master style sheet file so that the at least second copy of the master style sheet file has a second subset of the attributes specifying at least a second segment of the source information;

generating first presentation material, in response to the source information and the first derivative style sheet file, for presenting as a first view on the limited size display screen for a first segment of the certain source information; and

generating at least second presentation material, in response to the source information and the at least second derivative style sheet file, for presenting as at least a second view on the limited size display screen for at least a second segment of the certain source information, wherein the first and at least second views together present all of the certain portion of source information on the limited size display screen, instead of presenting the certain portion on the certain, larger display screen.

2. The method of claim 1, wherein generating the respective derivative style sheets comprises adding link attributes to the respective derivative style sheets such that links are included in the presentation materials for navigating among the respective views.

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

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

5. A computer system comprising:

a processor; and

a memory coupled to the processor, wherein the memory is enabled to store program instructions, wherein the processor is operable to execute the program instructions for;

generating a first derivative style sheet file from a first copy of a master style sheet file, wherein the master style sheet file specifies, as a set of attributes, a certain portion of source information for presenting on a certain display screen, wherein the set of attributes exceeds an amount of information capable of being displayed by the limited size display screen in a single view, and wherein generating the first derivative style sheet file includes;

deleting ones of the attributes from the first copy of the master style sheet file so that the first copy of the master style sheet file has a first subset or the attributes specifying a first of the source information;

generating a second derivative style sheet file from a second copy of the master style sheet file, including;

deleting ones of the attributes from the second copy of the master style sheet file so that the second copy of the master style sheet file has a second subset of the attributes specifying a second segment of the source information;

generating first presentation material, in response to the source information and the first derivative style sheet file, for presenting as a first view on the limited size display screen for a first segment of the certain source information; and

generating second presentation material, in response to the source information and the second derivative style sheet file, for presenting as a second view on the limited size display screen for a second segment of the certain source information.

6. The system of claim 5, wherein generating the respective derivative style sheets comprises adding link attributes to the respective derivative style sheets such that links are included in the presentation materials for navigating among the respective views.

7. The system of claim 5, wherein the first subset of attributes and the second subset of attributes have at least one common attribute.

8. The system of claim 5, wherein at least one of the source information attributes is excluded from the first subset of attributes and included in the second subset of attributes, and at least one of the source information attributes is excluded from the second subset of attributes and included in the first subset of attributes.

9. A computer program product, for creating multiple segments of information for presentation on a device having a limited size display screen, the computer program product having program logic on a computer readable storage media for causing a computer system to perform:

generating a first derivative style sheet file from a first copy of a master style sheet file, wherein the master style sheet file specifies, as a set of attributes, a certain portion of source information for presenting on a certain display screen, wherein the set of attributes exceeds an amount of information capable of being displayed by the limited size display screen in a single view, and wherein generating the first derivative style sheet file includes;

deleting ones of the attributes from the first copy of the master style sheet file, so that the first copy of the master style sheet file has a first subset of the attributes specifying a first segment of the source information;

generating a second derivative style sheet file from a second copy of the master style sheet file, including;

deleting ones of the attributes from the second copy of the master style sheet file so that the second copy of the master style sheet file has a second subset of the attributes specifying a second segment of the source information;

generating first presentation material, in response to the source information and the first derivative style sheet file, for presenting as a first view on the limited size display screen for a first segment of the certain source information; and

generating second presentation material, in response to the source information and the second derivative style sheet file, for presenting as a second view on the limited size display screen for a second segment of the certain source information.

10. The computer program product of claim 9, wherein generating the respective derivative style sheets comprises adding link attributes to the respective derivative style sheets such that links are included in the presentation materials for navigating among the respective views.

11. The computer program product of claim 9, wherein the first subset of attributes and the second subset of attributes have at least one common attribute.

12. The computer program product of claim 9, wherein at least one of the source information attributes is excluded from the first subset of attributes and included in the second subset of attributes, and at least one of the source information attributes is excluded from the second subset of attributes and included in the first subset of attributes.
