A social network describes an entity's relationship with other entities for interacting. The digital world currently consists of many isolated communities or domains that enable entities to form social networks within each community but not across communities because of the undisclosed, incomplete or incompatible connectivity protocols and data representation. A specification for the social network profile and policy is presented in this paper with the aim to address these issues by providing a common representation for defining the entity's relations and their social attributes, and its connectivity expectations and preferences. Furthermore, this profile and policy specification paves the path for supporting entities in automating their actions and managing their social networks.
