11. The computer-implemented method of claim 10 , wherein the plurality of states of the content interface comprise a first state of the content interface and a second state of the content interface; and the method further comprising: upon receiving a selection of the interface element corresponding to the first state of the content interface, providing the first state of the content interface comprising a smaller context pane adapted to display a less rich view of the contextual data; and upon receiving a selection of the interface element corresponding to the second state of the content interface, providing the second state of the content interface comprising a larger context pane adapted to display a richer view of the contextual data.
10. A computer-implemented method for providing a context pane with semantic zoom, the method comprising: providing one or more selectable interface elements corresponding to a plurality of states of a content interface, the interface elements operative to transform the content interface between the plurality of states, the states of the content interface corresponding to different size configurations of a content pane and a context pane, the different size configurations of the content pane and the context pane corresponding to a different richness of contextual data displayed in the context pane; providing a database storing the contextual data, wherein the contextual data includes data identifying users who are authorized to access content displayed in the content pane and data corresponding to activities performed by the users who are authorized to access the content; providing a plurality of selectable tabs in the context pane, each of the tabs corresponding to a category of contextual data; displaying a list of the users permitted to access the content as a first category of contextual data upon receiving a selection of one of the plurality of selectable tabs and displaying an activity stream showing activities performed by users in the list of the users permitted to access the content upon receiving a selection of another one of the plurality of selectable tabs; receiving a selection of one of the interface elements; and transforming between the states of the content interface according to the selected interface element, wherein said transforming between the states of the content interface comprises displaying the activity stream showing activities in different levels of detail.
