A documents control apparatus includes an attribute sharing unit that
shares an attribute of a document with another documents control
apparatus, an edit processing unit that edits the attribute, and a
switching unit that determines whether the attribute is shared with the
other documents control apparatus. The switching unit switches the edit
of the attribute based on the determination. If the attribute sharing
unit does not share the attribute, the switching unit allows the edit
processing unit to edit the attribute as requested. If the attribute
sharing unit shares the attribute, the switching unit controls the
operation of the edit processing unit.
