Abstract

The present invention relates to a method and program product for facilitating the maintenance of current bookmarks and preventing the loss of information associated with a bookmark. In one aspect, the invention bookmarks a Uniform Resource Locator (URL) associated with one or more HTML documents at a user'"'"'s request and creates a database table containing each bookmarked URL. The source code of the bookmarked URL is scanned for embedded links which are stored in the table according to the related bookmarked URL. To ensure that the bookmarks are current, a periodic verification of the status of a bookmarked URL is performed. A change in the location or/and contents of the one or more bookmarked HTML documents results in one or more actions to prevent the loss of data to the user. In one embodiment, the database table is refreshed to reflect any changes to the content of the HTML documents. In another embodiment, where a bookmarked HTML document has been moved to a new URL, the table is updated with a forwarding URL, i.e., the original URL is replaced with the new URL. Where a forwarding URL is not available, a backup document containing the stored embedded links related to the original URL is created.

Claims

1. A method of verifying a bookmark, comprising the steps:

(a) storing, as a bookmark in at least a first data structure, a first network information address of a document having content;

(b) identifying embedded network information addresses within the content;

(c) automatically searching, at a predefined frequency, for the document located at the first network information address to determine whether the first network information address is retrievable;

(d) wherein if the first network information address is retrievable, determining whether the document has been moved to a second network information address different from the first network information address; and

(e) wherein if the first network information address is not retrievable, making the identified embedded network information addresses available to a user via the stored bookmark.

2. The method of claim 1, wherein the first network information address is a Uniform Resource Locator (URL).

3. The method of claim 1, wherein the document located at the first network information address is a Hypertext Markup Language (HTML) document.

4. The method of claim 1, wherein (b) is performed at a user-defined frequency.

5. The method of claim 1, wherein if the document has been moved to the second network information address, replacing the first network information address in the first data structure with the second network information address.

6. The method of claim 1, wherein determining whether the document has been moved to the second network information address comprises detecting only a single hypertext link in a forwarding document located at the first network information address.

7. The method of claim 6, further comprising determining whether the content has changed by comparing a stored first date to a second date returned by a server, wherein the first date is stored during step (a).

8. The method of claim 1, wherein if the document has not been moved to the second network information address, determining whether the content has changed.

9. The method of claim 8, wherein determining whether the content has changed comprises comparing a stored first date to a second date returned by a server, wherein the first date is stored during step (a).

10. The method of claim 1, the first data structure has at least a first data field related to the first network information address.

11. The method of claim 10, further comprising, storing each identified embedded network information address in a second data structure containing one or more second data fields which relate to the embedded network information addresses.

12. The method of claim 11, wherein the first data structure and the second data structure are the same.

13. The method of claim 11, further comprising generating a verification table containing the first data field and the one or more second data fields.

14. The method of claim 1, further comprising, storing each identified embedded network information address in the first data structure.

15. The method of claim 14, wherein (c) comprises attempting to download the document located at first network information address, wherein a successful attempt indicates that the first network information address is retrievable and an unsuccessful attempt indicates that the first network information address is irretrievable.

16. The method of claim 15, wherein if the document has been moved to the second network information address, replacing the first network information address in the first data structure with the second network information address;

and wherein making the identified embedded network information addresses available to the user via the stored bookmark comprises replacing the first network information address in the first data structure with a temporary document containing the one or more embedded network information addresses.

17. The method of claim 15, wherein if (c) indicates that the first network information address is retrievable, determining whether the content has changed.

18. The method of claim 17, wherein determining whether the content has changed comprises comparing a first date stored in the first data structure to a second date returned by a server.

19. A computer implemented automated method for maintaining bookmarks, comprising:

(a) storing, in a data structure, a bookmark to a network information address of a document having content;

(b) scanning the content for one or more embedded network information addresses, wherein if any embedded network information addresses are found, storing the embedded network information addresses; and

(c) periodically determining whether the network information address has changed and;

(d) wherein if the network information address has changed;

determining whether a forwarding network information address is provided; and

if not, associating the bookmark with the embedded network information addresses.

20. The method of claim 19, further comprising performing (c) at a user-defined frequency.

21. The method of claim 19, wherein periodically determining whether the network information address has changed comprises attempting to download the document.

22. The method of claim 19, wherein the network information address is a URL and the document is an HTML document.

23. The method of claim 19, wherein periodically determining whether the network information address has changed comprises loading the network information address from the data structure and attempting to locate the document on a server, wherein a successful attempt indicates that the network information address has not changed and an unsuccessful attempt indicates that the network information address has changed.

24. The method of claim 23, wherein if the network information address has changed, and if the forwarding network information address is provided, replacing the bookmark network information address in the data structure with the forwarding network information address.

25. The method of claim 19, wherein if the network information address has not changed, determining whether the content has changed.

26. The method of claim 25, wherein determining whether the content has changed comprises comparing a first date stored in the data structure to a second date returned by a server.

27. A signal bearing medium for storing a program that when executed by a computer performs an operation comprising:

(a) downloading a bookmark network information address of a document having content;

(b) storing the bookmark network information address in a data structure;

(c) scanning the content for one or more embedded network information addresses, wherein if any embedded network information addresses are found, storing the embedded network information addresses in the data structure; and

(d) periodically determining whether the document is retrievable at the bookmark network information address, wherein;
