Abstract
Abstract Apparatus and method for distributing data from a central digital data processing system (603) to remote digital data processing systems (505) end apparatus (709) for storing data In digital data processing systems. The central digital data system creates a data descriptor (305) which describes the data and Its source location. The central system provides the data descriptor to the remote systems. The remote systems employ the data descriptor to retrieve the data to be distributed end place it in a destination. A given digital data processing system may function as both a central eystem end a remote system. The data descriptor may be provided to the remote systems by means of magnetic media (405, 407) or a network and the data may be retrieved from magnetic media or via a network (615) When retrieval is via a network, the source of the data is an inventory library (707). The inventory library may be part of the central system or may be part of a different host system (509). The destination (709) includes a live library (1513) and a run library (1517). The data is retrieved to the live library, and when it is to be used, the remote system installs the data by placing it in the run library. Both test end production versions of data may be present in the destination and a test version may be converted to a production version. If both test and production versions are simultaneously present. one is always in the live library and the other always in the run library.

Claim 2
Dependent Claim
35 words
1) Apparatus for distributing data to a digital computer system which includes a source (309) for data to be distributed and a destination (311) for the data to be distributed and which is characterized by:
Claim 3
Dependent Claim
20 words
(1) system data distribution means (303) for creating a system data descriptor (305) describing the data to be distributed; and
Claim 4
Dependent Claim
20 words
(1) system data distribution means (303) for creating a system data descriptor (305) describing the data to be distributed; and
Claim 5
Dependent Claim
35 words
(2) system retrieval means (307) having access to the source and the destination for receiving the system data descriptor and responding thereto by transferring the data to be distributed from the source to the destination.
Claim 6
Dependent Claim
35 words
(2) system retrieval means (307) having access to the source and the destination for receiving the system data descriptor and responding thereto by transferring the data to be distributed from the source to the destination.
Claim 7
Dependent Claim
46 words
2) The apparatus of claim 1, further characterized in that: the apparatus includes a plurality of sources; the system data descriptor specifies one of the plurality of sources; and the system retrieval means transfers the data to be distributed from the specified source to the destination.
Claim 8
Dependent Claim
62 words
3) The apparatus of claim 1, further characterized in that: the system data descriptor further includes a destination operation descriptor (313) describing operations to be performed on the distributed data at the destination; and the system retrieval means further responds to the system data descriptor by performing operations to be performed on the distributed data as specified in the destination operation descriptor.
Claim 9
Dependent Claim
92 words
4) The apparatus of claim 1, further characterized in that: the data to be distributed is stored in a module (831) in the source; the module has protection information associated therewith; the system data descriptor includes a protection descriptor (943) containing a copy of the protection information for the module; and the system retrieval means further responds to the system data descriptor by copying the data to be distributed into a module (831) in the destination and associating protection information therewith which is identical to the copy contained in the protection descriptor.
Claim 10
Dependent Claim
77 words
5) The apparatus of claim 1, further characterized in that: the digital computer system includes media reading (407) and writing (405) means; the source is media (401) means whereupon the system data distribution means has written the system data descriptor and the data to be distributed; and the system retrieval means reads the system data descriptor from the media means and responds thereto by transferring the data to be distributed from the media means to the destination.
Claim 11
Dependent Claim
65 words
6) The apparatus of claim 1, further characterized in that: the source is remote from the destination and is connected thereto by data transfer means (511) for transferring data between the source and the destination; and the system retrieval means responds to the system data descriptor by employing the data transfer means to transfer the data to be distributed from the source to the destination.
Claim 12
Dependent Claim
69 words
7) The apparatus of claim 1, further characterized in that: the digital computer system includes a plurality of component digital computer systems (503, 507, 509); any of the component systems may be a central system (503) including the system data distribution means; and any of the component systems may be a remote system (505) including the system retrieval means and having access to the source and to the destination.
Claim 13
Dependent Claim
