Document events
Document events refer to the read, modify and create events
concerning the documents of a workspace. Using the action 
in the action menu of a folder, you may
inspect the events pertaining to the documents in this folder and all its
subfolders and sub-subfolders. You may select the documents that a certain
member has created or modified and let BSCW show you who has
read these documents and how often. You may also select the documents that a
certain user has read to view who has created these documents. Thus,
you may investigate questions like:
• Who has read the documents I created?
• Which documents of the workspace have I read so far?
In addition, you may have the events concerning your current document selection visualized as a document event map. Document event maps are graphs where the nodes stand for documents and users, and the edges stand for the events, always connecting a document and a user node. The edges have different colours signalling different kinds of events: A green edge leading from user X to document D, e.g., stands for the event that user X has read document D. Red edges symbolize create events, yellow edges symbolize modify events. The following figure shows an example of an event map.

You may get an overview of all document events in the current folder by having a look at a document event map that covers all documents of the current folder. Using this presentation, you may investigate questions like:
• who is a very active contributor to the workspace, i.e. who has created many documents or who has modified many documents?
• which documents are of most interest to workspace members, i.e. which documents have been read by many workspace members?
While any read access to a document, i.e. opening, archiving, copying etc., counts as a read event in document events, only replacing, revising and editing a document count as a modify events.
