Abstract: A location database may be configured to store a set of subjective, arbitrary, and/or ephemeral names assigned to a location by various users. When a user of a device arrives at a particular location, the device may retrieve and present to the user the set of names assigned to the location. Moreover, the names may be associated with a privacy designation, which may permit an author of a location name to indicate whether the name of a location should be shared with the public or restricted to access by the user (or to a specified group of users, etc.) Other access criteria may also be specified, e.g., read-only access to a name for the public and read/write access to a particular group of users. Within the set of names of a location, particular names may be designated as authoritative, and may be presented to users with emphasis.

Abstract: A digital facility is made available from a source to users via an electronic communication medium. At least one of the users is associated with an access permission that enables the user to access at least one of the digital facilities. At least one of the users is associated with a grant permission that enables the user to give to another user a permission with respect at least one of the digital facilities.
