A method to identify a child process to a parent process in an operating system includes obtaining a token and login identifier from the operating system. The parent process creates a remote procedure call communications endpoint to communicate with the child process. Thereafter, a child process is spawned by the parent process. A child-initiated request to communicate with the parent process is then received by the parent process. In order to verify the identity of the child-initiated request, the parent process impersonates the child process and receives as identifier that identifies the requestor child process. The requestor process identifier and the spawned child identifier are compared. Based on the comparison, the parent process responds to the child-initiated request. In another embodiment, process identifiers are used by the parent process to verify the identity of a child process the requests communication with the parent process.

Trusted communications with child processes

Methods, systems, and computer-readable media for a method of propagating signals across a web graph. A signal describes a document or otherwise provides useful information about a document in a web graph. A web graph is a collection of documents that are related to one another through links, such as hyperlinks. The signals are propagated in the sense that information from the related pages is associated with the target page even though the information may not be directly found in the target page. This information may then be used by a search engine to determine that a particular page is relevant to a search query.

Propagating signals across a web graph

An arbitration policy resolves software applications operating on a single unit of data in a manner conflicting with other applications that operates on the same data or properties of the data. This is accomplished through picking an entity type of one application to have priority over an entity type of another application when both entity types map to a same property which caused the conflict. This allows user to observe the data in a consistent manner when switching between applications.

Arbitration mechanisms to deal with conflicting applications and user data

Rich structured data for items in a file system that allows different kinds of data to be identified by metadata is mapped into a set of search properties for a desktop search service, which is a flat list. This is applicable to any rich structured data that should be mapped into search properties for a desktop search service. Included is an installation mechanism to install these mappings and an execution infrastructure for utilizing the generated SQL from the mappings to extract search properties from items.

Defining and extracting a flat list of search properties from a rich structured type

The present invention relates to a system and methodology to facilitate interoperability and compatibility between disparate data systems. In one aspect, a file transformation system is provided having at least one file associated with one or more unstructured properties. A file property handler manipulates the unstructured properties in accordance with one or more structured properties associated with a structured object store environment. If an unstructured file is to be operated in the context of a structured object store environment, a promotion operation is performed to update unstructured properties in the file with structured properties suitable for operation in the structured object store environment. If a promoted item were to be manipulated in the structured object store environment, a demotion operation or reverse transformation is performed to update properties in the file.
