Models: Dexter Layers

• The Dexter model has three layers and focuses on the middle one, Storage.
• The topmost or outer layer, Run-time, deals with presentation and user interaction.
• The bottom or lower layer, Within-Component, deals with each media type.
• The anchor interface bridge the gap between Storage, that deals with nodes as objects, and Within-Component, where anchors are connected to the proper (portion of) objects.
• The presentation specification interface allows for hypertext and other special behavior.
