Abstract

A method includes receiving an event indicating an action associated with a first file has been performed by a user using a first client. The action is unrelated to transmitting the first file to another client. The method also includes automatically extracting content from the first file in response to the event using the first client and generating metadata to associate with the content, and transmitting, using the first client, the content and the metadata to a peer client if the peer client and the first client are currently operating and visible to each other on a network. The timing of the transmission is determined automatically after the event is received.

Claims

1. A method comprising:

receiving an event indicating an action associated with a first file has been performed by a user using a first client, wherein the action is unrelated to transmitting the first file to another client;

automatically extracting content from the first file in response to the event using the first client and generating metadata to associate with the content; and

transmitting, using the first client, the content and the metadata to a peer client if the peer client and the first client are currently operating and visible to each other on a network, wherein the timing of the transmission is determined automatically after the event is received.

2. The method of claim 1, wherein the action that is unrelated to transmitting a file is a file access or a file save, and the extracted content from the first file is a copy of the file or a copy of the contents of the file.

3. The method of claim 1, further comprising receiving from a server an indication that the server is configured to transmit the content to a requesting client;

and having received the indication and if the peer client is not currently networked to the first client, transmitting the content and the metadata to the server.

4. The method of claim 3, further comprising receiving requirements from a server, locating the metadata that meets the requirements, and selecting the content associated with the metadata for transmission to the peer client.

5. The method of claim 4, wherein the requirements include time stamp values or data bit values.

6. The method of claim 5, further comprising extracting additional content from a plurality of files using the first client in response to a plurality of events occurring on the first client and transmitting the additional content to the peer client based on one or more priority algorithms that specify an order in which the additional content is to be transmitted.

7. The method of claim 1, wherein transmitting the content and metadata to a peer client includes transmitting the content and the metadata to a server, the first client receiving an indication from the server that the server is configured to transmit the content and the metadata to the peer client.

8. The method of claim 1, wherein transmitting the content and metadata to a peer client includes transmitting the content and the metadata to a second client, the first client receiving an indication from the second client that the second client is configured to transmit the content and the metadata to the peer client.

9. The method of claim 1, further comprising indexing the content before it is transmitted to the peer client so that one or more symbols included in the content are formatted as keys operable to identify the content.

10. The method of claim 1, further comprising extracting content from a second file independent of an event occurrence, indexing the content from the second file, and transmitting the indexed content to the peer client.

11. The method of claim 1, wherein extracting the content from the first file includes converting the content of the first file into hypertext markup language (HTML) or text.

12. The method of claim 1, wherein extracting the content of the first file includes generating a copy of the first file that retains the first file'"'"'s original file formatting.

13. The method of claim 1, further comprising increasing a throughput threshold for limiting an amount of content passed between the first client and the peer client if an indication is received at the first client that a network connection between the first client and the peer client has a bandwidth that exceeds a predetermined bandwidth value.

14. The method of claim 1, further comprising associating an expiration date with the content before it is transmitted to the peer client.

15. The method of claim 1, further comprising transmitting a request to delete the content from the peer client if the content is deleted from the first client.

16. A computer system having one or more servers comprising:

a table manager module to receive an indication from a first client that a user has performed an action on a file that is unrelated to a transfer of the file, the indication including content extracted from the file and a metadata value assigned to the content;

a data table to store the content extracted from the file on the first client and the metadata value;

an interface to receive from a second client a request for content that is associated with one or more metadata values within a specified metadata value range; and

a selection module to initiate transmission of the content to the second client if the metadata value associated with the content is within the specified metadata value range.

17. The system of claim 16, wherein the metadata value includes a time stamp that indicates when the action performed on the file occurred, and the metadata value range includes a sequential range of time stamp values that indicate a period of time.

18. The system of claim 16, further comprising an active client list that includes identifiers for clients from which requests for content have been received by the interface within a predetermined period of time, the active client list being used by the table manager module to determine if the content has been transmitted to all listed active clients before the table manager module issues a delete command to remove the content from the data table.

19. The system of claim 16, further comprising a space quota that includes a limit on an amount of storage space for received content, the space quota being used to trigger a deletion of at least a portion of the content from the data table when the quota is exceeded.

20. The system of claim 16, further comprising a list of source identifiers, one of which specifies the first client from which the content was received, the list of source identifiers being used to initiate a request for the content from the first client if the content has been deleted from the data table before the content is transmitted to the second client.

21. The system of claim 16, further comprising an authentication manager to transmit client identifiers for the first and second clients and a user identifier associated with the first and second clients to an external server for use in reconstructing the content if the content stored in the data table becomes inaccessible.

22. The system of claim 16, further comprising a throughput threshold that includes a limit on an amount of data that is received by the interface within a predetermined time period, the throughput threshold being used by the interface to refuse the receipt of additional content if the amount of data received exceeds the threshold.

23. A system for sharing data across multiple clients comprising:

an event listener at a first client to receive a user-initiated action associated with a file, wherein the action is unrelated to transmitting the file to a second client;

an extractor at the first client to extract content from the file in response to the event and to generate metadata that is associated with the context; and

means for transmitting the content and the metadata from a first client to a second client.

24. A computer program product tangibly embodied in a tangible, machine-readable information carrier, the computer program product including instructions that, when executed, perform a method comprising:

receiving an event indicating an action associated with a first file has been performed by a user using a first client, wherein the action is unrelated to transmitting the first file to another client;

automatically extracting content from the first file in response to the event using the first client and generating metadata to associate with the content; and

transmitting, using the first client, the content and the metadata to a peer client if the peer client and the first client are currently operating and visible to each other on a network, wherein the timing of the transmission is determined automatically after the event is received.
