Abstract: 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.

Abstract: Installing the content-index definitions includes parsing content-index definitions in a schema, generation of appropriate SQL statements for data extraction and storing the SQL statements. A run time infrastructure for extracting data to be content-indexed from the highly structured entity types is provided. This logic includes looking up the type of the item and its associated entities that need to be content-indexed, executing the corresponding data extraction code (SQL statements) and sending it to a protocol handler for content-indexing. Also included is an execution infrastructure for utilizing the generated SQL from the mappings to extract search properties from items.

Abstract: A framework for data change notification includes a notification queue storing event notifications. Client applications can request event information regarding various data change events. For example, a client application can subscribe, via one or more APIs, to receive event information. The framework allows for session specific event notification mechanisms as well as durable event notification mechanisms that can be preserved across client sessions as well as server restarts. Innovative aspects of this invention include guaranteed delivery of event notifications, APIs to allow applications get summary of past events on the subscribed objects, automatic garbage collection/cleanup of notifications when a client session terminates.

Abstract: The subject invention provides a system and/or a method that facilitates tracking a data change to an entity within a data storage system at an entity level and at a sub-entity level. The data storage system can be a database-based file system, wherein an interface can receive at least one data change to an entity within the data storage system that in part represents complex instances of types. A track component can track additional data change information of one or more sub-entity levels of the entity when the entity participates in a synchronization (sync) relationship.

Abstract: The subject invention provides a system and/or a method that facilitates mapping a data base model to a database object. A type storage system can utilize a storage mapping of a file storage data model. The mapping can describe the database object created based at least in part upon a schema and how instances of the type described in the schema are stored and/or accessed. Furthermore, a query can be provided to find at least one of an item, a document, and/or a contact that satisfy at least one criterion. The type storage system can receive data, wherein the data is at least one of a schema, a data model, a type, a query, and query criteria via an interface to provide the storing and querying. Additionally, the type storage system can generate a view that exposes at least one instance of the type.

Abstract: The subject invention provides a system and/or a method that facilitates adapting at least two disparate file systems. A file system adapter can provide uniformity and/or seamless integration between a first file system and a second file system. The file system adapter can employ a file-backed item that is enriched by a file to provide at least one of a property to an item and a file stream associated with the item. The file-backed item can allow a manipulation by at least one of an API for the first file system and an API for the second file system.

Abstract: A programming interface for a computer platform can include various functionality. In certain embodiments, the programming interface includes one or more of the following groups of types or functions: those related to core file system concepts, those related to entities that a human being can contact, those related to documents, those common to multiple kinds of media, those specific to audio media, those specific to video media, those specific to image media, those specific to electronic mail messages, and those related to identifying particular locations.

Abstract: Various embodiments of the present invention are directed to a hardware/software interface system for a computer system for manipulating a plurality of discrete units of information at a hardware/software interface system level (“Items”), said Items interconnected by Relationships and where Items have Relationships to other Items. One such relationship between Items may be for the purposes of logically denoting to the hardware/software interface system wether one Item is public and accessible or private and unaccessible to another Item.
