Abstract

In accordance with embodiments, there are provided mechanisms and methods for tracking documents in an on-demand service. These mechanisms and methods for tracking documents in an on-demand service can enable embodiments to provide the sharing of documents and the tracking of whether one of the shared documents was changed. The ability of embodiments to provide the sharing of documents and the tracking can enable a safeguard that a user knows whether the document that they have in their possession is the most recent version.

In an embodiment, the shared documents are stored in a document management storage. In an embodiment, each file has an ID that includes version information for checking whether the document is the most recent version. In an embodiment, an application is downloaded onto the user system that automatically upon opening a document checks whether a document is the most recent version.

Claims

1. A method for tracking documents stored on behalf of a plurality of organizations, comprising:

receiving an original document to store on behalf of a first organization;

storing a copy of the original document to document management storage; and

sending a message to a user inviting the user to join a group of users that have authorization to access the document management storage, the message including at least instructions for installing an application on the user system for checking whether documents on the users system are current.

8. The method of claim 1, further comprising:

receiving a message from a user system including at least the unique identifier;

in response, checking whether a document stored at the user system is current, based on the unique identifier sent and a unique identifier stored with the original document, the document stored on the user'"'"'s system being a copy of the original document.

9. The method of claim 8, further comprising:

if it is determined that the document stored at the user'"'"'s system is not current, sending a message to the user requesting whether to send an update for the document stored on the user'"'"'s system.

10. The method of claim 8,

if it is determined that the document stored at the user'"'"'s system is not current and

if the user requests to update the document stored in the user'"'"'s system, sending the original document to the user.

11. The method of claim 1, further comprising:

applying a hash function to the original document, therein generating in a hash value, which is a checksum of the document;

assigning a version number to the original document,

storing the original document in the document management storage;

including the hash value and version number within the unique identifier in association with the storing of the original document;

embedding the unique identifier within the original document;

revising the original document;

repeating the applying of the hash function, therein computing a new hash value, and repeating the assigning of the version number;

revising the unique identifier by at least replacing the hash value within the unique identifier with the new hash value;

repeating the embedding;

sending a message to a user inviting the user to join a group of users that have authorization to access the document management storage, the message including at least instructions for installing an application on the user system for checking whether documents on the users system are current;

receiving a message from a user system including at least the unique identifier;

in response, checking whether a document stored at the user system is current, based on the unique identifier sent and a unique identifier stored with the original document, the document stored on the user'"'"'s system being a copy of the original document; and

if it is determined that the document stored at the user'"'"'s system is not current and

if the user requests to update the document stored in the user'"'"'s system, sending the original document to the user.

26. The computer readable medium of claim 1, the method further

applying a hash function to the original document, therein generating in a hash value, which is a checksum of the document;

assigning a version number to the original document,

storing the original document in the document management storage;

including the hash value and version number within the unique identifier in association with the storing of the original document;

embedding the unique identifier within the original document;

revising the original document;

repeating the applying of the hash function, therein computing a new hash value, and repeating the assigning of the version number;

revising the unique identifier by at least replacing the hash value within the unique identifier with the new hash value;

repeating the embedding;

sending a message to a user inviting the user to join a group of users that have authorization to access the document management storage, the message including at least instructions for installing an application on the user system for checking whether documents on the users system are current;

receiving a message from a user system including at least the unique identifier;

in response, checking whether a document stored at the user system is current, based on the unique identifier sent and a unique identifier stored with the original document, the document stored on the user'"'"'s system being a copy of the original document; and

if it is determined that the document stored at the user'"'"'s system is not current and

if the user requests to update the document stored in the user'"'"'s system, sending the original document to the user.

12. A method comprising:

receiving a copy of an original document from a document management storage on another system that serves multiple organizations, the copy including an unique identifier; and

tracking the copy by at least monitoring when the copy is opened,

when it is detected that the copy is opened, sending a message to the other system that includes at least the unique identifier, and

waiting to receive a reply to the message indicating whether the copy is current, the reply being based on the unique identifier sent in the message and a corresponding unique identifier in the original document.

13. A system comprising one or more computer readable media storing thereon
