Automatic layout of content in a design for a medium
A three-way separation of information in a document includes content, design and media aspects. This division supports automatic rendering to multiple forms of media such as print, Intranet, Internet, and OLE embedding. In a particular embodiment, the document is separated into its content, design and media aspects. Content, design, a medium specification are identified and layout is performed as per the three aspects. In one embodiment, an information data structure is provided that includes three tree structures: a design tree, a content tree and a media tree. A media division data structure is associated with a parent component in a composition. The parent component has a parent region in a medium and has child components. Each child component is associated with a child region of the medium. The media division data structure provides rules, properties and values for performing layout in a particular region of the medium. Layout may be performed on a server.

7. A computer-readable storage material as recited in claim 1 wherein the medium is a web site, in VRML format, in HTML format, or in a markup language format.
8. A computer-readable storage material as recited in claim 1 wherein the medium is in audio format or in video format.
9. A computer-readable storage material as recited in claim 1 wherein the laying out comprises adjusting the media specification.
10. A computer-readable storage material as recited in claim 9 wherein the adjusting comprises changing the relative sizes of at least two regions or sub-regions of the medium.
11. A computer-readable storage material as recited in claim 9 wherein the adjusting comprises changing the relative positions of at least two regions or sub-regions of the medium.
12. A computer-readable storage material as recited in claim 1 including further program instructions for performing steps comprising: changing an element of the content while adhering to the design description and to the media specification; and laying out the content using the design description such that the changed content fits the medium as specified by the media specification.
13. A computer-readable storage material as recited in claim 1 including further program instructions for performing steps comprising:
changing the design description while adhering to the content and to the media specification; and
laying out the content using the changed design description such that the content is arranged to fit the medium as specified by the media specification.
14. A computer-readable storage material as recited in claim 1 including further program instructions for performing steps comprising:
changing the media specification while adhering to the content and to the design description; and
laying out the content using the design description such that the content is arranged to fit a second medium as specified by the changed media specification.
15. A computer-readable storage material as recited in claim 1 wherein the design description is a custom design and whereby the document is presentable according to the custom design.
16. A computer-readable storage material as recited in claim 1 including further program instructions for performing steps comprising:
determining a source for the content, a source for the design description, and a source for the media specification.
17. A computer-readable storage material including program instructions for a computer executable method of presenting a document comprising content in a medium, the document further comprising one or more components, each component comprising one or more sub-components, the method comprising:
receiving the content;
receiving a design description, the design description comprising data defining relationships among the components and subcomponents;
receiving a media specification, the media specification defining one or more regions of the medium and one or more sub-regions of the regions, the media specification further associating the regions with the components and associating the sub-regions with the sub-components; and
laying out the content using the design description and the media specification such that the content is arranged to fit the medium, wherein
at least one document component or subcomponent is a software object comprising media, design and content facets, each facet having a set of values,
the software object is contained within multiple container objects,
the values of the design facet are determined by containment in a first container object,
the values of the content facet are determined by containment in a second container object, and
the values of the media facet are determined by containment in a third container object.
18. A computer-readable storage material including program instructions for a computer executable method of presenting a document in a medium, the document having component objects and subcomponent objects, the component and subcomponent objects having content, design and media facets having values, said method comprising:
determining content facet values of at least one set of component and subcomponent objects by containment in a first set of container objects;
determining design facet values of the at least one set of component and subcomponent objects by containment in a second set of container objects;
