Abstract

Information items from publishers are furnished to authorized subscribers by processing and storing the information in a central database and logging in each information item. Entitlement tables also are kept which indicate which subscribers are entitled to view the information. Information items which are new or which have not yet been distributed are published on a network distribution server at a central location. The network subscribers have local file servers which contain previously received information items stored in a relational database. Network subscribers who are authorized update their local file servers over the Internet with the undistributed or new information items.

Claims

1. In an information distribution system having a plurality of restricted publication sources, each restricted publication source disseminating publications each containing at least one information item, said restricted publication sources having a list of network subscribers authorized to receive said publications, a plurality of authorized network subscribers, each having a local server with SQL software adapted to answer subscriber queries from an updatable relational database residing on said local server, and an information management enterprise (IME), having an information processing, storage and distribution control center (IPSDCC), said IPSDCC having a computer with database storage means for storing a content database, a log entry database, and an entitlement database, said IME also having a network distribution server:

a method for distributing timely information from said restricted publication sources via the IME to said authorized network subscribers over a publicly accessible global information network, the method comprising the steps of;

(a) receiving and storing in said entitlement database a list of authorized network subscribers to each publication from said restricted sources;

(b) receiving in said IPSDCC the publications transmitted by said restricted sources to the IPSDCC;

(c) categorizing, editing and storing information items from the publications in said content database;

(d) creating and storing in the log entry database a log entry for each said information item having codes assigned to the log entry indicating date of the information item, publication in which the information item appeared, location of the information item in the content database, and whether the information item has been distributed;

(e) periodically accessing the log entry database and retrieving corresponding new information items from the content database;

(f) selecting network subscribers authorized to receive the information items from the list of authorized network subscribers in the entitlement database;

(g) preparing file transfer packages of new information items for said selected network subscribers;

(h) distributing the new information items by placing the file transfer packages on the distribution server for access by the local servers of the network subscribers, so as to allow the authorized network subscribers to update their updatable relational databases over the global information network; and

(i) altering the log entries for the new information items to indicate when they were distributed.

2. Method according to claim 1, including the additional steps of:

(c) accessing the log entry database and retrieving corresponding undistributed information items from the content database; and

(d) distributing the undistributed items by placing file transfer packages on the distribution server.

3. Method according to claim 1, including the additional steps of:

(l) collecting additional publications from open publication sources and storing information items from the additional publications in the content database; and

(m) carrying out steps (c), (d), (e), (g), (h), and (i) with respect to the information items from the additional publications.

4. Method according to claim 1, including the additional steps of:

(n) providing a Publisher Subscriber Agreement between each restricted source and each restricted network subscriber;

(o) providing an Electronic Distribution Agreement between each restricted source and the information management enterprise; and

(p) providing a Distributor Service Agreement between each restricted network subscriber and the information management enterprise.

5. Method according to claim 1, wherein the selecting step (f) and preparing step (g) include the substeps of:

accessing the entitlements database;

identifying knowledge workers who are entitled to view the information item for a selected authorized network subscriber; and

including knowledge worker entitlement data in the file transfer packages.

6. Method according to claim 1, wherein the categorizing, editing and storing step (c) and creating log entry step (d) comprise the substeps of:

automatically separating said information items received by the IPSDCC into first information items comprising timely textual news items, and other information items;

suspending said other information items from distribution;

automatically loading the first information items into the content database;

automatically creating an implicit log entry for each first information item;

manually editing and loading the other information items into the content database;

manually creating a log entry for the other information;

items; and

unsuspending the other information items to allow distribution.

7. Method according to claim 1, wherein the categorizing, editing and storing step (c) and creating log entry step (d) comprise the substeps of:

automatically separating said information items received by the IPSDCC into first information items comprising timely textual news items, second information items comprising structured numerical data and third information items requiring editing;

automatically loading the first information items into the content database;

automatically creating an implicit log entry for each first information item;

manually loading the second information items into the content database;

manually creating an explicit log entry for each second information item;

editing the third information items and manually loading them into the content database; and

automatically creating an implicit log entry for each third information item.
