Concepts are used throughout i2b2 for a number of things but they are primarily used in queries, defining a model for the timeline or in the image view.
By using the mouse, users will be able to drag concepts from the Ontology, Query Tool, or Timeline views. You may drag a single or multiple concepts from the view to the workspace.
