Publication number: 20070100959Abstract: A system, apparatus, and method are directed to managing customization of a subscription and/or an alert for an RSS feed over a network. An RSS Content Source (RCS) may provide feed templates that may be used to modify a subscription interface. The RCS may further provide additional feed templates that are useable to modify an RSS alert and/or the RSS content. Moreover, a RSS subscription service provider may also provide one or more feed templates. The feed templates may include co-branding information, advertisements, related RSS feeds, services related to the RCS's business, products available from the RCS, or the like. The feed templates may further change a look and feel of a subscription interface, and/or RSS alert to enhance subscriber loyalty, and improve business opportunities. In one embodiment, the feed templates include material that may change based, in part, on a subscriber's behavior.Type: ApplicationFiled: October 28, 2005Publication date: May 3, 2007Applicant: Yahoo!

Publication number: 20070100960Abstract: A system, apparatus, and method are directed to managing an alert to a subscriber based on a change of content at an RSS content source (RCS). A content collector identifies changes in content from various RCSs. In one embodiment, the RCS may notify the content collector of a change in content. In another embodiment, a crawler is used to identify an RCS with changed content based, in part, on a subscriber's request. Information about the RCS with changed content is provided to at least one of a plurality of matching engines using a load-balancing mechanism. Each of the matching engines manages a store that identifies subscribers that have requested an alert from a particular RCS. The matching engines further determine when the subscriber was last notified of a change in content from that RCS so that the subscriber is not notified multiple times of the same change.Type: ApplicationFiled: October 28, 2005Publication date: May 3, 2007Applicant: Yahoo!

Publication number: 20070100836Abstract: A system, method, and apparatus are directed to managing a subscription to an RSS feed. A search component enables searching over a network for content associated with an RSS feed. In one embodiment, the search component receives a search query in the form of a structured query language (SQL), Boolean expression, or the like. The search component may search for content based on the search query and validate the RSS feed associated with the results from the search. A list of validated RSS feeds may be sent to the user. The user may then select from the list and subscribe to a validated RSS feed. In addition, the user may employ the search query as an RSS feed. Thus, the same search may be performed automatically and the results compared to the previous search results. If a change in the search results is detected, the user may be alerted.Type: ApplicationFiled: October 28, 2005Publication date: May 3, 2007Applicant: Yahoo!
