Abstract
A system for associating application or system information with data files according to data file attributes. The system employs an Automatic Classification Selection (ACS) filter having an ordered sequence of rule-based declarations, each of which specifies a range of values for selected data file attributes. Each rule-based declaration includes specifications for data file attributes, any of which can be specified using wild-cards. Each data file is tested against the ordered declarations and the first declaration that matches the data file attributes is enabled to assign a classification to that data file. Because the ACS filter is declarative, it may be easily modified without programming expertise. Because any data file can be quickly sieved through the ACS filter, the data file class linkages need not be stored and thus are always dynamically updated in response to changes in data file attributes over time.
