BSCW groups the events related to an object in five event categories. Each category may individually be chosen for the Monitor (see section 5.3) and the Daily Workspace Activity Report (see section 4.2.5). In the entries in a folder page, each category is represented by a specific event icon:

this object is new to you, you have not seen it before (e. g. if you were just invited to a workspace).

indicates changes to the object -- for example, to the contents (if it is a document), to the address in a URL object, to the description of the object etc.

the object has been moved from one location to another.

there are recent modifications to objects in this folder. This icon is only displayed for folders; it provides a list of all 'modified' events somewhere within the folder, including its subfolders and the objects contained therein.

the object -- or an object inside it -- has been read or downloaded or copied. BSCW lists only the most recent 'read' event per user. events of this category are propagated to higher-level folders and are included in their lists of 'read' events.
