Abstract

Information is automatically shared among a plurality of remote/mobile data processing nodes which are temporarily and intermittently linked to a data processing server by distributing an information form to users corresponding to first remote/mobile nodes. A user may complete the form to create an instance of the form and define an instance distribution list. The instance is automatically distributed to users corresponding to the distribution list. As owner of the form, the user may also modify the form, and these modifications are also automatically distributed to the users at the third node. A second form may be linked to the form and automatically distributed to the third nodes as well. When distributing a file to a node, any other files which are required are also automatically distributed.

Claims

1. A method for transferring a first file from a data processing server to a remote/mobile data processing node which is temporarily and intermittently linked thereto for communication therebetween, said first file transferring method comprising the steps of:

identifying a second file which is required in order to use said first file at said remote/mobile node;

probing said node during a remote/mobile communication between said server and said remote/mobile node, to identify whether said second file is present at said remote/mobile node;

transferring said second file to said remote/mobile node during a remote/mobile communication between said server and said remote/mobile node, if said second file is not present at said remote/mobile node; and

transferring said first file to said remote/mobile node during a remote/mobile communication between said server and said remote/mobile node.

2. A method according to claim 1 wherein said steps of probing said node, transferring said second file and transferring said first file are all performed during a single remote/mobile communications link between said server and said remote/mobile node.

3. A method according to claim 1 wherein said probing step comprises the steps of:

establishing a remote/mobile communications link between said server and said remote/mobile node;

transmitting a message from said server to said remote/mobile node to determine whether said second file is present at said remote/mobile node;

receiving a response from said remote/mobile node at said server, to indicate whether said second file is present at said remote/mobile node; and

disconnecting said remote/mobile communications link between said server and said remote/mobile node.

4. A system for transferring a first file from a data processing server to a remote/mobile data processing node which is temporarily and intermittently linked thereto for communication therebetween, said first file transferring system comprising:

means for identifying a second file which is required in order to use said first file at said remote/mobile node;

means, responsive to said identifying means, for probing said node during a remote/mobile communication between said server and said remote/mobile node, to identify whether said second file is present at said remote/mobile node;

means, responsive to said probing means, for transferring said second file to said remote/mobile node during a remote/mobile communication between said server and said remote/mobile node, if said second file is not present at said remote/mobile node; and

means for transferring said first file to said first file to said remote/mobile node during a remote/mobile communication between said server and said remote/mobile node.

5. A system according to claim 4 wherein said probing means comprises:

means for establishing a remote/mobile communications link between said server and said remote/mobile node;

means responsive to said establishing means, for transmitting a message from said server to said remote/mobile node to determine whether said second file is present at said remote/mobile node;

means for receiving a response from said remote/mobile node at said server, to indicate whether said second file is present at said remote/mobile node; and

means, responsive to said receiving means, for disconnecting said remote/mobile communications link between said server and said remote/mobile node.

6. A computer program storage device which tangibly embodies a program of instructions executable on a plurality of remote/mobile data processing nodes which are temporarily and intermittently linked to a data processing server for communication therebetween, to perform a method for transferring a first file from the data processing server to the remote/mobile data processing node which is temporarily and intermittently linked thereto for communication therebetween, said first file transferring method comprising the steps of:

identifying a second file which is required in order to use said first file at said remote/mobile node;

probing said node during a remote/mobile communication between said server and said remote/mobile node, to identify whether said second file is present at said remote/mobile node;

transferring said second file to said remote/mobile node during a remote/mobile communication between said server and said remote/mobile node, if said second file is not present at said remote/mobile node; and

transferring said first file to said remote/mobile node during a remote/mobile communication between said server and said remote/mobile node.

7. A computer program storage device according to claim 6 wherein said steps of probing said node, transferring said second file and transferring said first file are all performed during a single remote/mobile communications link between said server and said remote/mobile node.

8. A computer program storage device according to claim 6 wherein said probing step comprises the steps of:

establishing a remote/mobile communications link between said server and said remote/mobile node;

transmitting a message from said server to said remote/mobile node to determine whether said second file is present at said remote/mobile node;

receiving a response from said remote/mobile node at said server, to indicate whether said second file is present at said remote/mobile node; and

disconnecting said remote/mobile communications link between said server and said remote/mobile node.
