9. A method for linking virtual world information with social collaboration platform information, the method comprising: executing by a processor residing on an information processing system, the following: storing, automatically and without user intervention, a virtual world user identifier that identifies a respective user of a plurality of users in at least one virtual world, the virtual world identifier being associated with a first contact list comprising a set of one or more virtual world contacts of the respective user, wherein each contact in the set of one or more virtual world contacts represents an avatar of other users of the at least one virtual world that is known by the respective user in the at least one virtual world, and wherein a unique virtual world identifier associated with each contact in the set of one or more virtual world contacts is stored within a set of user information of the respective user at the virtual world; storing, automatically and without user intervention, a social collaboration platform user identifier that identifies the respective user in a social collaboration platform, the social collaboration platform user identifier being associated with a second contact list comprising a set of one or more social collaboration contacts for the respective user, wherein each contact in the set of one or more social collaboration contacts represents a participant in the a social collaboration platform that is known by the respective user in the a social collaboration platform, and wherein a unique social collaboration platform identifier associated with each contact in the set of one or more social collaboration contacts is stored within a set of user information of the respective user at the social collaboration platform; obtaining, automatically and without user intervention, at least one of the set of one or more virtual contacts from the set of user information of the respective user at the virtual world and the set of one or more social collaboration contacts from the set of user information of the respective user at the social collaboration platform, for the respective user; linking, automatically and without user intervention, in response to the virtual world and social collaboration platform identifiers being stored, the virtual world user identifier to the social collaboration platform user identifier, wherein the linking comprises associating the virtual world user identifier and the social collaboration platform user identifier to a unique identifier associated with the respective user in a data model, wherein the unique identifier is separate and distinct from the virtual world user identifier and the social collaboration platform user identifier; determining, automatically and without user intervention, based on the linking, an association between at least one of each social collaboration contact of the set of one or more social collaboration contacts that has been obtained and the virtual world identifier of the respective user, and each virtual world contact of the set of one or more virtual world contacts that has been obtained and the social collaboration platform user identifier of the user; identifying, automatically and without user intervention, an information set associated with at least one of the virtual world user identifier and the social collaboration identifier based on the unique identifier, the information set being at least one of the set of one or more social collaboration contacts and the set of one or more virtual world contacts; and updating, automatically and without user intervention based on in response the identifying, the information set to include the association that has been determined, wherein the information set enables the user to perform at least one of the following: bi-directionally interact with the set of one or more social collaboration contacts from the at least one virtual world, or bi-directionally interact with the set of one or more virtual world contacts from the social collaboration platform.

A method for linking virtual world information with social collaboration platform information, the method comprising: executing by a processor residing on an information processing system, the following: storing, automatically and without user intervention, a virtual world user identifier that identifies a respective user of a plurality of users in at least one virtual world, the virtual world identifier being associated with a first contact list comprising a set of one or more virtual world contacts of the respective user, wherein each contact in the set of one or more virtual world contacts represents an avatar of other users of the at least one virtual world that is known by the respective user in the at least one virtual world, and wherein a unique virtual world identifier associated with each contact in the set of one or more virtual world contacts is stored within a set of user information of the respective user at the virtual world; storing, automatically and without user intervention, a social collaboration platform user identifier that identifies the respective user in a social collaboration platform, the social collaboration platform user identifier being associated with a second contact list comprising a set of one or more social collaboration contacts for the respective user, wherein each contact in the set of one or more social collaboration contacts represents a participant in the a social collaboration platform that is known by the respective user in the a social collaboration platform, and wherein a unique social collaboration platform identifier associated with each contact in the set of one or more social collaboration contacts is stored within a set of user information of the respective user at the social collaboration platform; obtaining, automatically and without user intervention, at least one of the set of one or more virtual contacts from the set of user information of the respective user at the virtual world and the set of one or more social collaboration contacts from the set of user information of the respective user at the social collaboration platform, for the respective user; linking, automatically and without user intervention, in response to the virtual world and social collaboration platform identifiers being stored, the virtual world user identifier to the social collaboration platform user identifier, wherein the linking comprises associating the virtual world user identifier and the social collaboration platform user identifier to a unique identifier associated with the respective user in a data model, wherein the unique identifier is separate and distinct from the virtual world user identifier and the social collaboration platform user identifier; determining, automatically and without user intervention, based on the linking, an association between at least one of each social collaboration contact of the set of one or more social collaboration contacts that has been obtained and the virtual world identifier of the respective user, and each virtual world contact of the set of one or more virtual world contacts that has been obtained and the social collaboration platform user identifier of the user; identifying, automatically and without user intervention, an information set associated with at least one of the virtual world user identifier and the social collaboration identifier based on the unique identifier, the information set being at least one of the set of one or more social collaboration contacts and the set of one or more virtual world contacts; and updating, automatically and without user intervention based on in response the identifying, the information set to include the association that has been determined, wherein the information set enables the user to perform at least one of the following: bi-directionally interact with the set of one or more social collaboration contacts from the at least one virtual world, or bi-directionally interact with the set of one or more virtual world contacts from the social collaboration platform. 15. The method of claim 9 , further comprising: receiving a virtual world identifier verification request from the social collaboration platform in response to social collaboration platform detecting a social collaboration platform event associated with the user; determining, in response to receiving the virtual world identifier verification request and based on the updating, that user is associated with the virtual world user identifier for virtual world; and notifying, in response to determining that the user is associated with virtual world user identifier, the social collaboration platform that the user is associated with the virtual world user identifier for the virtual world.
