Abstract

The present invention relates to a system 10 for generating a content hierarchy 12 for use in laying out content from a source 14 for display. The system comprises a content gatherer 16 co-operable with a source for gathering content from the source into content sub-groups dependent on the content type of the content; a design fragment populater 24 for populating at least one design fragment 19 using the gathered source content, the plurality of design fragments each comprising design parameters specifying how the source content can be laid out; and a content hierarchy assembler 32 for attaching the populated design fragment to a selected parent fragment 19 permitted for the populated design fragment, the parent fragment containing design parameters specifying how each design fragment can be laid out for display.

Claims

1. A system for generating a content hierarchy for use in laying out content from a source for display, the system comprising:

a content gatherer co-operable with a source for gathering content from the source into content sub-groups dependent on the content type of the content;

a design fragment populater for populating at least one design fragment using the gathered source content, the plurality of design fragments each comprising design parameters specifying how the source content can be laid out; and

a content hierarchy assembler for attaching the populated design fragment to a selected parent fragment permitted for the populated design fragment, the parent fragment containing design parameters specifying how each design fragment can be laid out for display.

2. A system as claimed in claim 1, wherein the content hierarchy comprises a parent locator and the assembler is arranged to assemble the content hierarchy by locating in the existing content hierarchy a parent fragment permitted for the instantiated design fragment and attaching the instantiated design fragment to the permitted parent fragment.

3. A system as claimed in claim 1 or 2, wherein the content hierarchy assembler is arranged to assemble the content hierarchy by instantiating a parent fragment permitted for the instantiated design fragment if such a permitted parent fragment cannot be located in the existing content hierarchy and attaching the instantiated design fragment to the permitted parent fragment.

4. A system as claimed in any one of the preceding claims, wherein the content hierarchy assembler is arranged to assemble the content hierarchy by attaching the permitted parent fragment to at least one parent fragment above the permitted parent fragment in the hierarchy until all of the instantiated parent fragments are connected to a root fragment of the content hierarchy.

5. A system as claimed in any one of the preceding claims, wherein the plurality of design fragments each comprise attributes specifying one or more parent fragment types to which the design fragment is permitted to be attached in the content hierarchy.

6. A system as claimed in any one of the preceding claims, wherein the content hierarchy assembler is arranged to instantiate each parent fragment with attributes specifying the number of child fragments to which the parent fragment can be attached and/or the type of child fragment to which the parent fragment can be attached.

7. A system as claimed in any of the preceding claims, wherein the content gatherer is co-operable with a source for gathering content from the source into content sub-groups dependent on the content type of the content and the populator is arranged to populate content of each content type into one or more selected design fragments suitable for the content type.

8. A method for generating a content hierarchy for use in laying out content from one or more sources for display, the method comprising:

gathering content from a source;

populating at least one design fragment from a plurality of stored design fragments using the gathered source content, the plurality of design fragments each comprising design parameters specifying how the source content can be laid out; and

assembling the content hierarchy by attaching the populated design fragment to a selected parent fragment permitted for the populated design fragment, the parent fragment containing design parameters specifying how each design fragment can be laid out for display.

9. A method as claimed in claim 8, wherein assembling the content hierarchy comprises locating in the existing content hierarchy a parent fragment permitted for the populated design fragment and/or assembling the content hierarchy comprises instantiating a parent fragment permitted for the populated design fragment if such a permitted parent fragment cannot be located in the existing content hierarchy.

10. A method as claimed in claim 8 or 9, wherein assembling the content hierarchy comprises attaching the permitted parent fragment to at least one parent fragment above the permitted parent fragment in the content hierarchy until all of the instantiated parent fragments are connected to a root fragment of the content hierarchy.

11. A method as claimed in any one of claims 8 to 10, wherein each design fragment when instantiated comprises attributes specifying one or more parent fragment types to which the design fragment is permitted to be attached in the content hierarchy.

12. A method as claimed in any one of claims 8 to 11, wherein the design fragments and content hierarchy comprise logical structures for laying content for display independent of a display surface.

13. A method as claimed in any one of claims 8 to 12, wherein part or all of the content hierarchy describes a specific layout dependent on the properties of a selected display surface.

14. A computer readable medium having a computer program recorded thereon, the program being executable by a computer to carry out the method of any of claims 8 to 13.

15. Computer apparatus comprising a processor programmed to perform the method of any of claims 8 to 13.
