Abstract

A method for maintaining an alterable document history log in a data processing system having multiple resource objects which are accessible by a plurality of users within the data processing system. A history log is created and associated with each resource object for which documentation of selected activities is desired. A list of one or more specified types of activities is generated and utilized to filter all activities which take place with respect to a particular resource object in order that the occurrence of selected activities may be documented. A characterization of these activity types is recorded in association with the document history log such that subsequent users may ascertain what types of activity occurrences have been recorded. In the depicted embodiment of the present invention access to a resource object may be locked and the list of specified types of activity altered. Thereafter a new characterization of activity types is recorded in association with the document history log and access to the resource object is unlocked. In this manner a user may create a document history log associated with a particular resource object and thereafter periodically alter the list of activity types to be recorded within the document history log while also recording a characterization of the types of activities which have been recorded during specified periods of time.
