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. Your application provides a thumbnail sketch of the edition data, which the Edition Manager displays in the preview area of the publisher dialog box. Your preview of the edition in this dialog box should provide a visual cue about the type of information that the user has selected to publish. This preview, too, should provide a visual cue about the type of information the edition contains.
