A system and method for synchronizing a database having metadata and raw data. Metadata may be fully synchronized between two systems, with copies stored on both systems. Raw data may be selectively synchronized, so that a client system need not store all of the raw data locally. When disconnected, the client system may identify certain portions of the raw data to store locally, and such data may be synchronized when reconnected to a server system.

Ghosted synchronization

A system and method for synchronizing a database comprising raw data and metadata derived from the raw data, but when the metadata has not yet been updated. The raw data and the metadata are first synchronized, with the raw data having been assigned a version number. After synchronization, any stale metadata will be updated and assigned the same version number as the raw data.

Synchronization with derived metadata

Various embodiments of the present invention are directed to systems and methods for synchronizing mixed elements (MEs) comprising structure data and unstructured filestreams between peer computer systems in a hardware/software interface system environment that does not permit snapshotting of large unstructured ME filestreams during synchronization. For several such embodiments, the method comprises synchronizing the ME in two steps, one for snapshotting the structured data component of the ME (as well as the cv of the filestream but not the filestream itself) and one for locking and transmitting the filestream to the receiving sync peer if and only if, after being locked, it is determined that the filestream is unchanged from the time of the ME data component snapshot.

Systems and methods for synchronization of items without snapshots

A system and method for providing a location owner's location information to third parties (location consumers) is provided. The location server obtains an owner profile controlling access to the location owner's location information. A location consumer requests the location owner's location information through a location request. The location server determines whether the location consumer is authorized to access the location owner's location information according to access information in the owner profile. If the location consumer is authorized to access the information, the location server obtains location information from a location provider and returns the location information to the location consumer. The location consumer may also subscribe to a location owner, such that when an identified subscription event occurs, the location server notifies the location consumer of the location owner's current location. The location server repeatedly notifies the location consumer when the subscription event occurs or until the subscription is terminated.

System and method for providing personal location information to location consumers from a location services server

A system and method for providing location information associated with a location owner to location consumers. A location server includes an owner profile for controlling access to the owner's location information. The owner profile contains a time period during which particular location consumers are authorized to access location information associated with the location owner. In response to a location consumer requesting the location owner's location information, the location server determines whether the request lies within the time period associated with the location consumer. If the request lies within the time period associated with the location consumer, the location server obtains location information from a location provider and transmits the location information to the location consumer.

System and method for controlling access to location information

A system and method for providing location information associated with a location owner to location consumers. A location server includes an owner profile for controlling access to the owner's location information. The owner profile contains information describing a user-defined geographic area. In response to a location consumer requesting the location owner's location information, the location server obtains data describing a current location of the location owner. The server determines if the current location falls within a set of boundaries that defines the user-defined geographic area. If the current location falls within a set of boundaries that defines the user-defined geographic area, the location server transmits the location information to the requesting location consumer.
