Data Models 1.X

Motivation

Points #3 and #5 of the charter state or imply the need for a robust identity and social networking data model. Point #5 is repeated here:

Provide a social relationship data integration framework that enables these relationships to be persistent and reusable across application boundaries.

It organizes relationships into a set of distinct social contexts within which a person expresses different personas and roles. The existence of common identity and social relationship framework makes possible new kinds of applications. Applications that make it easy to manage identities, relationships, reputation and trust within and across multiple contexts. Of particular interest are applications that work on behalf of a user to manage their own profiles, relationships, and reputation across their various personal and professional groups, teams, and other organizational affiliations while preserving their privacy. These applications could, for example, provide users with the ability to: discover new groups through shared affinities; find new team members based on reputation and background; sort, filter and visualize their social networks. Applications could be used by organizations to build and manage their networks of networks.
