Abstract
Abstract A data management system comprises a computerized data storage and retrieval utility for integrating data sequences produced by independent data processing operations into graphs by linking stored data sequences ("nodes") according to user-definable relationships. The machine permits users to subdivide graphs into independently accessable contexts and permits users to identify contexts and the nodes and links within each context according to user-defined attributes. Further included are search routines for locating groups of contexts, data sequences and links having similar attributes. The machine also maintains an archive of versions of contexts, nodes and links referenced according to their creation time.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
128 words
A data management method for implementation by data processing means for receiving commands and data sequences from a user, for storing nodes in data storage means, each node comprising a separate data sequence, for reading nodes stored in said data storage means, and for transmitting data to said user, the method comprising the steps of: storing nodes in said data storage means, each node comprising a separate data sequence received from said user; identifying each other of the stored nodes as being included in one of a plurality of contexts wherein each context comprises a separate group of the stored nodes; and receiving from said user and storing in said data storage means link data referencing at least one pair of said stored nodes as having a relationship.
Claim 2
Dependent Claim
128 words
A data management method for implementation by data processing means for receiving commands and data sequences from a user, for storing nodes in data storage means, each node comprising a separate data sequence, for reading nodes stored in said data storage means, and for transmitting data to said user, the method comprising the steps of: storing nodes in said data storage means, each node comprising a separate data sequence received from said user; identifying each other of the stored nodes as being included in one of a plurality of contexts wherein each context comprises a separate group of the stored nodes; and receiving from said user and storing in said data storage means link data referencing at least one pair of said stored nodes as having a relationship.
Claim 3
Dependent Claim
52 words
The data management method according to claim 1 wherein one node of at least one pair of said stored nodes referenced as having a relationship is included in one of said contexts while another node of said at least one pair of said stored nodes is included in another of said contexts.
Claim 4
Dependent Claim
89 words
The data management method according to claim 1 further comprising the steps of: receiving from said user a first data sequence and a command indicating said first data sequence is to replace a second data sequence comprising a particular node stored in said data storage means; comparing said first data sequence with said second data sequence to determine a set of differences therebetween; modifying said first node in accordance with said first data sequence; and storing in said data storage means node history data representing said set of differences.
Claim 5
Dependent Claim
53 words
The data management method according to claim 1 wherein the step of identifying each of the stored nodes as being included in one of a plurality of contexts comprises the substep of storing in said data storage means context data indicating which of said stored nodes are included in each of said contexts.
Claim 6
Dependent Claim
50 words
The data management method according to claim 4 further comprising steps of: creating second nodes by copying first nodes included in one of said plurality of contexts; and storing in said data storage means context data indicating that said second nodes are included in another of said plurality of contexts.
Claim 7
Dependent Claim
65 words
The data management method according to claim 5 comprising the step of creating second link data referencing one of said second nodes as having a relationship to another node by copying first link data referencing one of said first nodes as having a relationship to said another node, wherein said one of said second nodes was created by copying said one of said first nodes.
Claim 8
Dependent Claim
150 words
The data management method according to claim 4 further comprising the steps of: receiving from said user a first data sequence and a command indicating said first data sequence is to replace a data sequence comprising one of said first nodes; comparing said first data sequence with said data sequence comprising said one of said first nodes to determine a first set of differences therebetween; storing in said data storage means first node history data representing said first set of diffeneces; receiving from said user a second data sequence and a command indicating said second data sequence is to replace a data sequence comprising one of said second nodes; comparing said second data sequence with said data sequence comprising said one of said second nodes to determine a second set of differences therebetween; and storing in said data storage means first node history data representing said second set of differences.
Claim 9
Dependent Claim
40 words
The data management method according to claim 1 further comprising the steps of: receiving from said user link attribute data indicating at least one link attribute characterizing said relationship; and storing said link attribute data in said data storage means.
Claim 10
Dependent Claim
51 words
The data management method according to claim 8 further comprising the steps of: reading link data and link attribute data stored in said data storage means, and determining from the data read which of said at least one pair of stored nodes have a relationship characterized by a particular link attribute.
Claim 11
Dependent Claim
44 words
The data management method according to claim 1 further comprising the steps of: receiving from said user context attribute data indicating at least one context attribute characterizing at least one of said contexts; and storing said context attribute data in said data storage means.
Claim 12
Dependent Claim
42 words
The data management method according to claim 10 further comprising the steps of: reading context attribute data stored in said data storage means; and determining from the data read which of said plurality of contexts are characterized by a particular context attribute.
Claim 13
Dependent Claim
45 words
The data management method according to claim 1 further comprising the steps of: receiving from said user node attribute data indicating at least one node attribute characterizing as least one of said stored nodes; and storing said node attribute data in said data storage means.
