The subject invention pertains to systems and methods of data item synchronization. More specifically, the invention concerns synchronization of data entities utilizing an intermediary or shared storage system and associated data store. Each client sync device can include or be associated with an interface that facilitates communication between client synchronization devices and the intermediary storage system. The interface can send change information to the shared store utilizing change data packets including a data change attribute, a prerequisite knowledge attribute and a learned knowledge attribute. The data change attribute can specify changes to be made to certain data, while the attribute can include a complete copy or reference to a complete copy or single instance of data.

Client store synchronization through intermediary store change packets

A data model models a social network. The data model can be embodied as a person profile schema and a connector profile schema. The person profile schema defines properties of persons in the social network. The connector profile schema defines connectivity properties of persons that connect a searcher to the persons in social network that the searcher desires to find. Query languages can be based on the data model and can be used to express queries of social networks. Queries can be for persons, for connecting persons, or for both.
