Uniform resource identifier decoration to enable connectivity for instant messaging providers serving non-authoritative namespaces

摘要

A technique for interconnecting users of different instant messaging services without requiring the users to change their account identifiers. A first user of a primary messaging service can communicate with a second user of a second, federated messaging service, where the first user is associated with a non-managed domain of the primary messaging service. When the first user sends a message to the second user, the primary messaging service decorates or modifies the first user's identifier as the sender so that the message, when received, appears to have come from a managed domain of the primary messaging service rather than from the non-managed domain. When a message from the second user is sent to the first user, the first user's identifier is undecorated in a reverse operation.
