Use the terms publish and subscribe to describe the Edition Manager features. Each edition has an icon that is visible from the Finder. Figure 2-1 shows the default edition icon. The name that the user specifies for the edition is located next to the edition icon. Figure 2-2 illustrates a document containing a single publisher, its corresponding edition, and a subscriber to the edition in another document.
Data always flows in one direction, from publisher to edition to subscriber.
Documents that contain publishers and subscribers do not have to be open at the same time to share data. Whenever the user saves a document that contains a publisher, the edition changes to reflect the current data from the publisher. All subscribers update their contents from the edition. Any number of subscribers can subscribe to a single edition. Figure 2-3 shows the dialog box that your application should display when the user chooses Create Publisher.
