shows the architectural concept of meme media. Meme media architecture is based on 1) Wrapper architecture, 2) Frame architecture, 3) Compound document architecture, 4) Update-dependency architecture, and 5) Model-ViewController (MVC) architecture. In the meme media platform, each functional component is wrapped as a visual component that provides standard interface (figure 2 (b)). The interface allows users to manipulate the component with simple mouse operations like drag-and-drop. Each component provides a set of slots to hold its property values. Users can change the slot values of a component to customize the behavior of the component. Slots are also used as input/output ports for communication with other components. When users drag one component and drop it at another, the parent-child relationship is established between these two components and physically connected as a composite component (figure 2 (a)). The child is embedded in the view of the parent. Then, the platform allows uses to define a slot connection in a pair of the parent and its child, which defines a data flow between them. With this data exchange via slot, combined components communicate with each other and work together. Conceptually, it is similar to the use of AV-system components. A parent component and its child have an update-dependency relationship. When the state of the parent is changed, it is notified to its children. Then children look at the connected slot and behave depending on the value of the slot.
