Abstract

A computing device includes a view control that manages presentation of electronic content on the computing device. The presentation can include displaying content, audibly playing back content, and so forth. The view control is made available to multiple different applications on the computing device. To use the view control, an application provides to the view control an indication of a resolver for the view control to use. The electronic document includes references to electronic content, and the view control requests the referenced electronic content from the resolver. The resolver obtains the referenced electronic content, decodes (e.g., decompresses, decrypts, etc.) the obtained electronic content, and returns the decoded electronic content to the view control for display or other presentation.

Claims

1. A method implemented in a computing device including an application, a view control, and multiple resolvers, the method comprising:

obtaining, from one of the multiple resolvers by the view control, a decoded electronic document that includes one or more relative references to content to be displayed as part of the decoded electronic document, an indication of an encoded electronic document having been received by the view control from the application;

determining, by the view control, that the content referenced by one of the one or more relative references is to be retrieved from the multiple resolvers, the view control needing no knowledge of how the referenced content is encoded;

requesting, by the view control in response to determining that the content referenced by the one relative reference is to be retrieved, the content referenced by the one relative reference from the multiple resolvers;

acquiring, by the multiple resolvers, context that comprises information used by the multiple resolvers to decode the referenced content;

determining at least one of the multiple resolvers to decode the referenced content based, at least in part, on the context acquired;

receiving, by the view control from the at least one of the multiple resolvers in response to the request, the referenced content after the referenced content has been decoded by the at least one of the multiple resolvers; and

displaying, by the view control, the referenced content.

2. A method as recited in claim 1, the electronic document comprising an electronic book or electronic magazine.

3. A method as recited in claim 1, the receiving comprising receiving the referenced content after the referenced content has been decoded by being decompressed by the at least one of the multiple resolvers.

4. A method as recited in claim 1, the receiving comprising receiving the referenced content after the referenced content has been decoded by being decrypted by the at least one of the multiple resolvers.

5. A method as recited in claim 1, the electronic document comprising a markup language document.

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

exposing, by the view control, an application programming interface to the application;

receiving, by the view control, an identifier of the electronic document from the application by the application invoking a method of the application programming interface; and

the requesting the content comprising the view control providing to the one of the multiple resolvers the relative reference to the content by invoking a method of an application programming interface exposed by the resolver.

7. A method as recited in claim 1, further comprising:

receiving, by the view control, an indication of the multiple resolvers from the application.

8. A method as recited in claim 1, the at least one of the multiple resolvers being one of multiple resolvers in the computing device, the indication of the electronic document comprising a uniform resource indicator, and the method further comprising:

determining, by the view control and based on the uniform resource locator, at least one of the multiple resolvers to decode the referenced content, an indication of the at least one of the multiple resolvers being embedded in the uniform resource indicator.

9. A method as recited in claim 1, the receiving the referenced content from the at least one of the multiple resolvers comprising receiving the referenced content from the at least one of the multiple resolvers as a stream as the decoded content becomes available from the at least one of the multiple resolvers.

10. A method as recited in claim 1, the determining comprising determining, by the view control, that the content referenced by the one or more relative references is to be retrieved as the electronic document is being displayed.

11. A method as recited in claim 1, the obtaining occurring in response to the view control receiving an identifier of an electronic document specifying the electronic document to be displayed by the view control.

12. A method as recited in claim 11, further comprising the identifier of the electronic document having been obtained from a user input to the application.

13. A method as recited in claim 1, further comprising:

providing, by the application, a context to the view control via an application interface;

providing, by the view control to the multiple resolvers, the context; and

applying, by the multiple resolvers, a personalization to the content referenced by the one of the one or more relative references, the personalization indicated by the context.

14. A computer-readable storage medium having stored thereon multiple instructions that implement an application, a view control, and multiple resolvers and that, responsive to execution by one or more processors of a computing device, cause the one or more processors to perform acts comprising:

receiving, by the view control from the application, an indication of an electronic document that includes one or more references to content;

obtaining, from one of the multiple resolvers by the view control, the electronic document;

determining, by the view control, that the content referenced by one of the one or more references is to be retrieved from the multiple resolvers, the view control needing no knowledge of how the referenced content is encoded;

requesting, by the view control in response to determining that the content referenced by the one reference is to be retrieved, the content referenced by the one reference from the multiple resolvers;

acquiring by the multiple resolvers, context that comprises information used by the multiple resolvers to decode the referenced content;

determining at least one of the multiple resolvers to decode the referenced content based, at least in part, on the context acquired; and

receiving, by the view control from the at least one of the multiple resolvers in response to the request, the referenced content after the referenced content has been decoded by the at least one of the multiple resolvers.

15. A computer-readable storage medium as recited in claim 14, the electronic document comprising a program, the content referenced by the one reference comprising a portion of the program, the referenced content having been decoded by being decrypted by the at least one of the multiple resolvers, and the acts further comprising running, by the view control, the program.

16. A computer-readable storage medium as recited in claim 14, the receiving comprising receiving the referenced content after the referenced content has been decoded by being decrypted by the at least one of the multiple resolvers.

17. A computer-readable storage medium as recited in claim 14, the receiving comprising receiving the referenced content after the referenced content has been personalized by the at least one of the multiple resolvers for a user of the computing device.

18. A computer-readable storage medium as recited in claim 14, the acts further comprising:
