Abstract

Techniques are discussed whereby hyperlinks that exist in an on-line document can be automatically updated (re-linked) when the location of the document to which a link points changes. In one embodiment, the administrator of the on-line document is notified by E-mail when a link destination pointed to by that document has changed. Comparison of the old document content to the new content, if any, is used to facilitate a determination whether to automatically re-link or remove the appropriate hyperlink. In alternate embodiments, receiving sites or trusted third parties are authorized to update links to documents on the receiving site contained in documents on a feeding site.

Claims

1. An apparatus for updating linking information of a link from a first document to a second document, wherein:

the first document is stored on a first computer;

the second document is stored on a second computer;

the second document has an associated network address;

the first document comprises linking information including the associated network address of the second document;

a communication interface is arranged between the first computer and the second computer;

the second computer is configured to send a message over the communication interface to the first computer when the network address associated with the second document has changed;

the message comprises an executable option that replaces the linking information comprised in the first document, wherein the replacement of the linking information updates the associated network address of the second document; and

the message includes the entire content of the second document.

2. A system for updating linking information of a link from a first document to a second document, wherein:

the first document is stored on a first computer;

the second document is stored on a second computer;

the second document has an associated network address;

the first document comprises linking information including the associated network address of the second document;

a communication interface is arranged between the first computer and the second computer;

the second computer is configured to send a message over the communication interface to the first computer when the network address associated with the second document has changed;

the message comprises an executable option that replaces the linking information comprised in the first document, wherein the replacement of the linking information updates the associated network address of the second document; and

the message includes the entire content of the second document.

3. A method of updating linking information of a link from a first document to a second document, wherein:

the first document is stored on a first computer;

the second document is stored on a second computer;

the second document has an associated network address;

the first document comprises linking information including the associated network address of the second document;

a communication interface is arranged between the first computer and the second computer; and

the method comprises the following steps;

1) the second computer sends a message over the communication interface to the first computer when the network address associated with the second document has changed, wherein the message includes the entire content of the second document;

2) the first computer optionally executes an executable option comprised in the message that replaces the linking information comprised in the first document; and

3) if the first computer executes the executable option, then the associated network address of the second document is updated in the first document.

4. A computer readable medium bearing instructions for updating linking information of a link from a first document to a second document, wherein:

the first document is stored on a first computer;

the second document is stored on a second computer;

the second document has an associated network address;

the first document comprises linking information including the associated network address of the second document;

a communication interface is arranged between the first computer and the second computer;

said instructions being arranged to cause one or more processors upon execution thereof to perform the steps of;

1) the second computer sends a message over the communication interface to the first computer when the network address associated with the second document has changed, wherein the message includes the entire content of the second document;

2) the first computer optionally executes an executable option comprised in the message that replaces the linking information comprised in the first document; and

3) if the first computer executes the executable option, then the associated network address of the second document is updated in the first document.
