Abstract: A method is disclosed for address book owners to link to a publisher's contact information profile, and establish an automatic updates relationship with the publisher. Upon establishing this relationship, when a publisher modifies his or her profile to reflect updated contact information, the publisher's updated profile information may then automatically be published to an address book owner's address book so that the address book owner's contact for the publisher is automatically updated to reflect the new information in the profile. Thus, the publisher's contact in the address book owner's address book may be automatically updated as a result of a publisher updating his or her profile, and without any action on the part of the address book owner.

Abstract: Systems, methods, apparatus, data structures, and computer-readable media are described which provide techniques for managing data storage. In an implementation, a method includes examining a role map to determine which of a plurality of roles are applicable to a request to interact with at least one of a plurality of items. The request is received via an application programming interface (API) that is available over a network and one or more of the items reference a respective item of data. Access to the at least one item is permitted based on a role definition which describes differing access rights available for the item based on which of the roles is applicable to the request.
