Computer networking system, method of document retrieval in document management system, document management program and media for document management

A document management system coupled to a network, comprising:

• a first communications apparatus comprising:
• a first storing means for storing a plurality of documents;
• and
• a certificate issuing means for issuing a certificate ticket giving authorization to replicate a specific document from said plurality of documents stored by the first storing means;
• a second communications apparatus comprising:
• a second storing means for storing the specific document replicated using the certificate ticket from said plurality of documents stored in the first storing means;
• and
• a third communications apparatus comprising:
• a request issuing means for issuing a replication request for requesting the first communicating apparatus to issue the certificate ticket when requiring replication of the specific document by the second communications apparatus.

A document management method comprising the steps of:

• first causing a client terminal to issue a replication request to a first server to allow a second server to replicate a specific document from among a plurality of documents stored in the first server;
• second causing the first server to issue a certificate ticket to the client terminal in response to the replication request;
• third causing the client terminal to transfer the certificate ticket to the second server;
• fourth causing the second server to transfer the certificate ticket to the first server;
• and
• fifth causing the first server to transfer the specific document from among the plurality of documents stored in the first server to the second server in response to the certificate ticket transferred from the second server.

A computer-readable program for a document management embodied on an information storage medium, comprising processing routines executed by a computer system:

• a first operation causing a client terminal to issue a replication request to a first server which allows a second server to replicate a specific document from among a plurality of documents stored in the first server;
• a second operation causing the first server to issue a certificate ticket to the client terminal in response to the replication request, the certificate including information for allowing the second server to replicate the specific document from among the plurality of documents;
• a third operation causing the client terminal to transfer the certificate ticket to the second server;
• a fourth operation causing the second server to transfer the certificate ticket to the first server;
• and
• a fifth operation causing the first server to transfer the specific document from among the plurality of documents stored in the first server to the second server in response to the certificate ticket transferred from the second server.

A computer-readable medium having stored thereon computer-executable instructions which when executed perform a document management method, the method comprising the step of:

• a first operation causing a client terminal to issue a replication request to a first server to allow a second server to replicate a specific document from among a plurality of documents stored in the first server;
• a second operation causing the first server to issue a certificate ticket to the client terminal in response to the replication request, the certificate including information for allowing the second server to replicate the specific document from among the plurality of documents;
• a third operation causing the client terminal to transfer the certificate ticket to the second server;
• a fourth operation causing the second server to transfer the certificate ticket to transfer the first server;
• and
• a fifth operation causing the first server to transfer the specific document from among the plurality of documents stored in the first server to the second server in response to the certificate ticket transferred from the second server.
