Abstract
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 (28) 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.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
127 words
A method for classifying data files in a computer system having means for storing a plurality of data files each having one or more file attributes, comprising the steps of: establishing at least one Automatic Class Selection (ACS) filter in said storage means wherein said ACS filter includes an ordered plurality of rule declarations each specifying a range of values for a plurality of said file attributes and at least one file management class; testing in sequence each said rule declaration for coincidence with the file attributes of a first said data file until identification of the first said rule declaration that coincides with said first data file attributes; and assigning to said first data file the file management class specified in said first coincident rule declaration.
Claim 2
Dependent Claim
42 words
A method as claimed in Claim 1 wherein said file attributes include a plurality of file identifiers and a plurality of file characteristics and wherein each said rule declaration specifies a value for at least one of said plurality of file characteristics.
Claim 3
Independent Claim
29 words
A method as claimed in any of Claims 1 or 2 wherein said assigning step includes the step of: storing said assigned file management classification in said storage means.
Claim 4
Independent Claim
28 words
A method as claimed in any of the preceding claims wherein said plurality of file identifiers includes a file name, a file directory and a file storage group.
Claim 5
Independent Claim
29 words
A method as claimed in any of Claims 2 to 4 wherein said plurality of file characteristics includes a file size designation and one or more file type designations.
Claim 6
Independent Claim
22 words
A method as claimed in any of the preceding claims wherein said assigned file management class refers to an executable ACS procedure.
Claim 7
Independent Claim
45 words
A method as claimed in any of the preceding claims wherein said file attributes include a plurality of file identifiers and a plurality of file characteristics and wherein each said rule declaration specifies a value for at least one of said plurality of file characteristics.
Claim 8
Dependent Claim
135 words
A computer system including means for storing a plurality of data files each having one or more file attributes, and a computer file management system for automatically classifying said data files in accordance with said file attributes, said management system comprising: filter means having an ordered plurality of rule declarations each specifying values for a plurality of said file attributes and at least one file management class; tester means coupled to said filter means for testing in sequence each said rule declaration for coincidence with the file attributes of a first said data file and for identifying the first said rule declaration that coincides with said first data file attributes; and link means coupled to said tester means for assigning to said first data file a management class specified in said first coincident rule declaration.
Claim 9
Dependent Claim
43 words
A computer system as claimed in Claim 8 wherein said file attributes include a plurality of file identifiers and a plurality of file characteristics and wherein each said rule declaration specifies a value for at least one of said plurality of file characteristics.
Claim 10
Dependent Claim
31 words
A computer system as claimed in any of Claims 8 or 9 further comprising: means coupled to said link means for storing said assigned file management classification in said storage means.
Claim 11
Dependent Claim
30 words
A computer system as claimed in any of Claims 9 or 10 wherein said plurality of file identifiers includes a file name, a file directory and a file storage group.
Claim 12
Dependent Claim
30 words
A computer system as claimed in any of Claims 9 to 11 wherein said plurality of file characteristics includes a file size designation and one or more file type designations.
Claim 13
Dependent Claim
31 words
A computer system as claimed in any of Claims 8 to 12 further comprising: means coupled to said link means for storing said assigned file management classification in said storage means.
Claim 14
Dependent Claim
38 words
A computer system as claimed in any of Claims 8 to 13 further comprising: means coupled to said link means for executing an ACS procedure responsive to the assignment of a management class to said first data file.
