Abstract: A computer-implemented method of managing collaboration in an enterprise application includes creating an annotation that corresponds to at least a first document and a second document, the first document having a first document format and the second document having a second document format. The computer-implemented method can further include mapping the annotation to a workflow process. An annotation management system includes multiple document repositories to store documents, an annotation repository to store annotations, wherein each annotation references a document stored in a corresponding document repository, and an annotation application to allow collaborators to view at least some of the annotations, allow at least one of the collaborators to search the annotations, and allow at least one of the collaborators to apply a filter to the annotations.
