Abstract: A mechanism is provided for detecting and disregarding application specific nodes contained in shared XML documents. The techniques described involve determining one or more application specific nodes within XML documents and performing path expression evaluations of the XML documents as if the nodes are not present. In one embodiment, a mechanism is provided by which a user may specify the criterion that determine which subset of node in XML documents are to be ignored from path expression evaluations and evaluating a query that specifies a path operation based on a path and ignoring said identified nodes when evaluating said path operation.

Abstract: In a social networking system environment, users can give another user credits, a scarce commodity, as part of commenting on content posted by the other user. These credits can be used as a peer-to-peer recommendation signal, and they can also be used as input to a decision engine that determines what content to display in a highlights section that will be viewed by a wider audience and increasing the likelihood of further engagement with the content. Credits in a social networking system environment have scarcity value. In various embodiments, in order to increase the number of credits in the system, users buy them or an administrator distributes them. In some implementations, the total amount of credits in the system can decrease if a user cashes out the credits for real money. In some implementations, credits can be used to buy virtual or real-world gifts.

Abstract: Techniques for efficiently processing a query are provided. A query may specify a location path and a content path. The location path identifies the hierarchical location of a set of documents within a resource repository. The content path identifies hierarchical location of one or more nodes within the content of the set of documents. Computing the query includes using a repository index, based on the location path and the content path, to generate first results corresponding to the set of documents and second results corresponding to the one or more nodes. Final results of the query are based on the first results and second results. Another technique is provided for formatting a locator value in the repository index to support data that is stored object-relationally. Another technique is provided for storing index information about virtual content.

Abstract: A method and apparatus for efficiently processing a query that specifies a location path and a content path is provided. The location path identifies the hierarchical location of a set of documents within a resource hierarchy. The content path identifies hierarchical location of one or more nodes within the content of the set of documents. Computing the query includes using a resource hierarchy index, based on the location path, to generate first results corresponding to the set of documents. Computing the query also includes using a content index, based on the content path, to generate second results corresponding to the one or more nodes. Final results of the query are based on the first results and second results by, for example, joining the first and second results.
