• Problem:  how to organize nodes in such a way that sets of similar nodes can be easily traversed and allowing one node to belong to different sets and be focused differently according to the context in which it is accessed
• Motivation
• Forces:
    – Group nodes in contexts and connect them with links only appearing in that context
    – Nodes may look differently and be connected with different links
    – It’s not correct that a node contain contexual links
• Solution
    – Group nodes in sets(navigational contexts)
    – Allow the user to navigate sets sequentially
    – Allow the node to present context-specific information or links to other nodes
    – Use decorators(InContext nodes)
    – A context composed of Nodes, Links, Decorators, and a particular Context Node
