Abstract

A system for providing XML-based asynchronous and interactive feeds for Web applications that provides a highly efficient and extensible XML Javascript framework allowing easy insertion of a comment/news feed control into any Web page. The framework allows for reading of any XML format and provides a new and easy way for modifying the look-and-feel of the control via HTML templates with familiar XPath bindings. The rendering performed through the system supports both flat and indented (“threaded”) views for a comment thread. The system improves the parsing speed of incoming XML, and supports a flexible event model for others to develop plug-ins and mashups in the spirit of Web 2.0.

Claims

1. A method for providing a feed control in a parent Web page, comprising:

determining a data feed to be displayed to a local user, said data feed made up of a plurality of entries;

determining a template defining a format and appearance of one of said entries in said data feed;

loading said template from a template source;

loading said data feed onto a local device from a data feed source, wherein said loading includes retrieving data bindings from said template and using said data bindings retrieved from said template to indicate to a remote data server providing said data feed which data is relevant to displaying said data feed according to said template by encoding said data bindings retrieved from said template onto a link associated with said data feed in at least one request message sent to said remote data server providing said data feed, intercepting, by an agent on said remote server system, said at least one request, and, responsive to said data bindings encoded onto said link, sending at least one response from said remote server system to said local device, wherein said response includes only data specified by said data bindings encoded onto said link;

applying said template to each of said plurality of entries; and

displaying said plurality of entries to said local user.

2. The method of claim 1, wherein said data feed comprises an XML data feed.

3. The method of claim 2, wherein said data feed comprises a Web news feed and said plurality of entries are made up of news entries, each of said news entries including a summary and a link to a corresponding complete article.

4. The method of claim 2, wherein said data feed comprises a discussion thread and said plurality of entries are made up of comment entries, each of said comment entries including a comment body and an identifier of a comment author.

5. The method of claim 1, further comprising:

firing an entry formatted event to at least one service other than said data feed, and wherein said at least one service other than said data feed adds at least one display object to each of said entries; and

wherein said entry formatted event is fired followed after each of said entries is formatted based on said template.

6. The method of claim 5, wherein said at least one other service comprises a star rating service.

7. The method of claim 5, wherein said at least one other service comprises an inline personal information card.

8. The method of claim 5, further comprising firing a template received event to said at least one service other than said data feed upon receipt of said template by said local device.

9. The method of claim 8, further comprising firing a feed data received event to said at least one service other than said data feed upon receipt of said feed data from said feed data source.

10. The method of claim 9, further comprising firing a feed data ready for display event to said at least one service other than said data feed upon completion of formatting all of said entries of said data feeds.

11. The method of claim 1, further comprising:

determining an identifier of said template based on an automatically determined type of said data feed.

12. The method of claim 11, wherein said automatically determined type of said data feed is RSS.

13. The method of claim 11, wherein said automatically determined type of said data feed is ATOM.

14. The method of claim 1, wherein said local device comprises a local computer.

15. The method of claim 1, further comprising enabling said local user to post data back to said data feed source.

16. The method of claim 1, wherein said template is made up of HTML.

17. An apparatus including a computer readable memory, said computer readable memory having program code stored thereon operable when executed to cause a computer system to provide a feed control in a parent Web page to a local user by:

determining a data feed to be displayed to a local user, said data feed made up of a plurality of entries;

determining a template defining a format and appearance of one of said entries in said data feed;

loading said template from a template source;

loading said data feed onto a local computer system from a data feed source, wherein said loading includes retrieving data bindings from said template and using said data bindings retrieved from said template to indicate to a remote data server providing said data feed which data is relevant to displaying said data feed according to said template by encoding said data bindings retrieved from said template onto a link associated with said data feed in at least one request message sent to said remote data server providing said data feed, intercepting, by an agent on said remote server system, said at least one request, and, responsive to said data bindings encoded onto said link, sending at least one response from said remote server system to said local computer system, wherein said response includes only data specified by said data bindings encoded onto said link;

applying said template to each of said plurality of entries; and

displaying said plurality of entries to said local user.

18. A computer program product including a computer readable memory, said computer readable memory having program code thereon operable when executed to cause a computer system to provide a feed control in a parent Web page to a local user by:

determining a data feed to be displayed to a local user, said data feed made up of a plurality of entries;

determining a template defining a format and appearance of one of said entries in said data feed;

loading said template from a template source;

loading said data feed onto a local computer system from a data feed source, wherein said loading includes retrieving data bindings from said template and using said data bindings retrieved from said template to indicate to a remote data server providing said data feed which data is relevant to displaying said data feed according to said template by encoding said data bindings retrieved from said template onto a link associated with said data feed in at least one request message sent to said remote data server providing said data feed, intercepting, by an agent on said remote server system, said at least one request, and, responsive to said data bindings encoded onto said link, sending at least one response from said remote server system to said local computer system, wherein said response includes only data specified by said data bindings encoded onto said link;

applying said template to each of said plurality of entries; and

displaying said plurality of entries to said local user.
