Abstract: Systems and techniques are disclosed for enabling structured data to be associated with visual content in a manner that preserves the ability to edit the visual content using a content application such as a notebook application. Techniques and systems enable semantic notation to be introduced into selected regions of the visual content that indicate the visual content's structured data, allowing the content to be searched and accessed more easily by common search technologies and search engines. The semantic notation is assigned to the visual content so that the introduction of the semantic notation does not hinder the user's viewing or editing of the visual content with a content application. The inclusion of the semantic notation does not cause existing visual editing tools that do not understand the semantic notation to cease to function properly.

Abstract: A method for providing per-user aggregation of content accessible via a personalized user site may generally include receiving a request for metadata and determining whether the requested metadata is expired. The method may further include returning at least a portion of queried metadata prior to verifying whether the metadata is expired. The method may then include querying a change log for metadata modifications. The method may further include, if metadata has been modified since a previous query, sending a query to a community site for metadata that meets change criteria. The method may also include receiving the changed metadata and returning the changed metadata to a content group container within the personalized user site.
