20080197557 | Computer enabled document sequencing and decollation by reference to a rulebase - Method and apparatus for computer enabled sequencing and later desequencing of multiple electronic documents or their physical embodiments in a specific order, either in preparation or in actualization of transmission or storage, and decollation of those documents in the specified order. The sequence in which the documents are placed is determined by a computer process that reads a rulebase whose content determines the document sequence. The computer process uses that sequence to physically order the documents in either their magnetic or physical embodiments or both. Because of the resemblance to a stack of paper reports, this sequencing is referred to as “stacking”, and the decollation process is referred to as “unstacking”. The method uses software components identified as a rulebase creation application, a rulebase, a rulebase reading application, a document sequencer (“stacker”), a stack index, and a complementary document decollator (“unstacker”). | 08-21-2008 |
