Abstract

Markup language stylizations that may be applied to a source document are defined in overlay documents such that no special tags or markers are required in the source document to enable stylization via the overlay document. A manifest document defines an association between a source document and one or more overlay documents.

Claims

1. A method comprising:

receiving a request for a source document having a markup language;

identifying a manifest document associated with the source document, wherein the identifying comprises a website rendering engine examining a plurality of manifest documents to determine if the source document is referenced in the manifest document;

determining, at a website rendering engine, an overlay document to be applied to the source document as specified by the manifest document, the markup language including a source lock attribute to prevent;

one or more specified structures of the source document from modification by the overlay document;

one or more specified attributes of the source document from modification by the overlay document; and

one or more specified portions of content of the source document from modification by the overlay document;

generating, by the website rendering engine, a modified source document by applying the overlay document to the source document; and

in response to the request, returning the modified source document.

2. The method as recited in claim 1, wherein the source document does not contain special tags or markers to enable the generating of the modified source document.

3. The method as recited in claim 1, wherein identifying a manifest document comprises:

determining that a filename associated with the source document matches a filename specified in the manifest document; and

determining that an attribute of the source document fulfills an attribute condition specified in the manifest document.

4. The method as recited in claim 1, further comprising:

maintaining a copy of the modified source document;

receiving a second request for the source document;

determining that the source document has not been edited since the modified source document was generated;

determining that the overlay document has not been edited since the modified source document was generated; and

in response to the second request and the determining that the source document has not been edited and the determining that the overlay document has not been edited, returning the copy of the modified source document.

5. The method as recited in claim 1, further comprising:

maintaining a copy of the modified source document;

receiving a second request for the source document;

determining that the source document has been edited since the modified source document was generated;

generating a new modified source document by applying the overlay document to the source document that has been edited; and

in response to the second request, returning the new modified source document.

6. The method as recited in claim 1, further comprising:

maintaining a copy of the modified source document;

receiving a second request for the source document;

determining that the overlay document has been edited since the modified source document was generated;

generating a new modified source document by applying the overlay document that has been edited to the source document; and

in response to the second request, returning the new modified source document.

7. The method as recited in claim 1, the markup language further including a source unlock attribute, that when associated with at least one element of the source document, allows modification of the at least one element by the overlay document, the at least one element including an attribute, a portion of content or a structure of the source document.

8. One or more computer-readable storage media encoded with computer-executable instructions that, when executed, direct a computing system to perform acts comprising:

receiving a request for a source document having a markup language;

identifying a manifest document associated with the source document;

determining an overlay document to be applied to the source document as specified by the manifest document, the markup language including;

a first source lock attribute to prevent an attribute of an element of a section of the source document from modification by the overlay document;

a second source lock attribute to prevent content of an element of a section of the source document from modification by the overlay document; and

a third source lock attribute to prevent a specified structure of an element of a section of the source document from modification by the overlay document, the specified structure of an element being a structure in which content is presented on the source document; and

generating a modified source document by applying the overlay document to the source document.

9. The one or more computer-readable storage media as recited in claim 8, the markup language further including a fourth source unlock attribute added to unlock one or more portions of the source document, the one or more portions including at least one of an attribute of an element of a section of the source document, content of an element of a section of the source document or a specified structure of an element of a section of the source document, and the manifest document including a transform control tag to specify that the overlay document is only applied to at least one of the one or more portions of the source document that are unlocked.

10. The one or more computer-readable storage media as recited in claim 8, wherein the overlay document has a version, and the manifest document includes a compatibility list that specifies an overlay version with which the source document is compatible.

11. The one or more computer-readable storage media as recited in claim 10, wherein the compatibility list further specifies a document used to upgrade the overlay document to the overlay version with which the source document is compatible.

12. The one or more computer-readable storage media as recited in claim 8, wherein the manifest document includes an allow override attribute to indicate whether additional overlay documents may be applied after the overlay document is applied to the source document.

13. A system comprising:

memory;

one or more processors communicatively coupled to the memory to execute a website rendering engine stored in the memory, the website rendering engine to;

identify an overlay document to be applied to a source document;

generate a landmark hierarchy based, at least in part, on the overlay document, wherein each landmark represents a corresponding element that may be present in the source document;

search through elements in the source document to identify an element that corresponds to a first landmark in the landmark hierarchy;

identify an overlay directive associated with the first landmark, wherein the overlay directive associated with the first landmark comprises at least one command to modify the element that corresponds to the first landmark;

determine that the element that corresponds to a first landmark is absent a source lock attribute, wherein the source lock attribute prevents the element from being modified; and

generate a modified element by applying the overlay directive to the element that corresponds to the first landmark in the landmark hierarchy.

14. The system as recited in claim 13, the website rendering engine further to:

copy the source document to a modified source document; and

replace the element that corresponds to the first landmark in the landmark hierarchy with the modified element.

15. The system as recited in claim 13, wherein a portion of content of the modified element is modified by the applying of the overlay directive.

16. The system as recited in claim 13, wherein an attribute of the modified element is modified by the applying of the overlay directive.

17. The system as recited in claim 13, wherein a location of the modified element is modified by the applying of the overlay directive.

18. The system as recited in claim 13, wherein a structure of the modified element is modified by the applying of the overlay directive.
