A computing device is described that includes a user interface to receive contribution data of an enterprise and to display a sheet of the contribution data, an annotation interface module to receive one or more annotations for objects of the contribution data, a planning application to retrieve a context definition defining a context in which each of the annotations was received, and an annotation table to store each of the annotations and the context definition corresponding to each of the annotations. The user interface may be configured to output the annotations. The computing device may improve the collaborative process of developing multidimensional data. Users of the computing device may quickly and easily share their thoughts, questions, and comments about the data through annotations. Recreating an annotated sheet may be done efficiently by storing relevant coordinates.
