Abstract

An enhanced reader can provide a user with an off-line browsing experience that is essentially indistinguishable from an on-line browsing experience. In particular, the enhanced reader can allow a user to access essentially all elements (e.g. hypertext elements) in a selected page of web content as well as navigation information such as next/previous page. The user can use the navigation information to view web content in its original form as well as navigate from page to page in those situations where the web content spans more than one page. This off-line navigation experience can be enabled by software that automatically archives web content as part of a background process while a user'"'"'s device is in an on-line state. In this way, the user'"'"'s off-line and on-line browsing experiences are substantially indistinguishable from each other.

Claims

1. A computer implemented method for presenting essentially all content of an online article that spans more than one web page in a browser in an offline mode, the method comprising:

providing by the browser a URL associated with at least a first page of an article selected from a list of archived web articles;

using the URL to identify a memory location of stored web content data in a local memory device, the stored web content data corresponding to the selected at least first page of the article;

identifying navigation links associated with subsequent pages of the article, the navigation links being mapped to memory locations in the local memory associated with the subsequent pages;

retrieving the stored web content of the at least first page from the local memory location; and

presenting the web content of the at least first page by the browser.

2. The method as recited in claim 1, wherein the presented web content includes navigation links used to retrieve the stored web content of the subsequent pages of the article for presentation by the browser.

3. The method as recited in claim 2, wherein the web content data associated with the article is stored in the local memory prior to the selection only while the browser is on-line and in communication with a network arranged to provide the web content.

4. The method as recited in claim 2, wherein the first page web content data is stored to the local memory and navigation links associated with the subsequent pages are mapped to the memory concurrently with the user reading the article online and in communication with a network, and wherein when the network becomes unavailable while the user is reading the article, then web content data for the first page of the article and all subsequent pages of the article are automatically retrieved from the local memory as needed thereby preserving the online reading experience of the user while the network is unavailable.

5. A computer implemented method for presenting essentially all content of an online article by a browser in an offline mode, the archived version of the article comprising substantially all available online information associated with the article that spans more than one web page, the method comprising:

receiving a selection request of a page of the article, the selected page comprising a navigation link pointing to another page of the article;

providing by the browser a first URL associated with the selected page chosen from a list of web articles archived while the browser was in an online mode;

using the first URL to identify a first memory location of stored web content data in a local memory device, the stored web content data corresponding to the archived version of the selected page of the article;

retrieving the stored web content data of the selected page from the first memory location; and

presenting the retrieved web content data by the browser.

6. The method as recited in claim 5, wherein the navigation link is remapped during a preceding archival process of the article from a second URL associated with a world wide web location of the other page of the article to a second memory location in the local memory device associated with the archived version of the other page of the article.

7. The method as recited in claim 6, wherein when the browser is in an online mode receipt of the selection request for the selected page comprises directing the browser directly to the first URL.

8. The method as recited in claim 6, wherein the selected page web content data is stored to the local memory device and navigation links associated with other pages of the article are mapped to the memory concurrently with the user reading the article online and in communication with a network.

9. The method as recited in claim 8, wherein when the browser enters an offline mode while the user is reading the article, then web content data for the selected page of the article and all other pages of the article are automatically retrieved from the local memory device as needed thereby preserving the online reading experience of the user while the network is unavailable.

10. The method as recited in claim 6, wherein when a network providing online access to the browser is a slower communication protocol such as a 3G protocol a request to archive the selected page results only in the archiving of the selected page even when other pages are present and identifiable.

11. The method as recited in claim 6, wherein an amount of the online information associated with the archived version of the article can be user adjustable.

12. The method as recited in claim 11, wherein the amount of the online information associated with the archived version of the article at a maximum setting includes video and audio content associated with the article.

13. The method as recited in claim 5, wherein using the first URL to identify a first memory location of stored web content data comprises accessing a lookup table that maps original URL locations of archived articles to locations of those archived articles in the local memory device to determine the location of the stored web content data.

14. A non-transitory computer readable medium for storing computer instructions executed by a processor in a computing device having a web browser application, the method comprising:

computer code for receiving a request to store a selected page of an article located at a first URL while the web browser is in an online mode, the selected page comprising a navigation link pointing to another page with content from the article located at a second URL;

computer code for storing the first URL identified by the received request to a first memory location within a local memory device;

computer code for retrieving web content related to each page associated with the article; and

computer code for storing each page of the article to a second memory location in the local memory device.

15. The non-transitory computer readable medium as recited in claim 14, further comprising:

computer code for updating intra-article navigation links within each stored page of the article to correspond with locations of stored files within the second memory location; and

computer code for presenting a user-selectable link for accessing the selected page of the article,

wherein in an online state the user-selectable link directs the browser to the first URL recorded at the first memory location and in an offline state provides access to the archived article in a manner substantially indistinguishable from a normal web browsing experience.

16. The non-transitory computer readable medium as recited in claim 15, wherein the archived article is stored to the local device in a DOM tree format.

17. The non-transitory computer readable medium as recited in claim 15, wherein dynamic content associated with the archived article is captured during the storing process in a static format.

18. The non-transitory computer readable medium as recited in claim 17, wherein the captured dynamic content associated with the archived article can be periodically updated at selectable intervals during periods when the browser is in an online state.

19. The non-transitory computer readable medium as recited in claim 15, wherein when the browser is in an offline mode displaying the archived the article the browser still displays the URL originally associated with the online version of the article.

20. A computing system configured to archive essentially all of an article spread across more than one web page, the system comprising:

a local memory device; and

a browsing application, comprising;

an article selection control allowing a command from a user to be received that designate a web page for later off-line viewing,

a DOM tree generator configured to retrieve and parse web content data associated with a web page designated by the article selection control, wherein the parsing of the web content data allows the DOM tree generator to identify any other pages of the article that are available, wherein the DOM tree generator retrieves and parses web content of identified other pages, and wherein the parsed content of the selected page and other pages are saved to a location on the local memory device, and

a lookup table configured to correlate an original URL of the selected page and other pages with locations of associated parsed content on the local memory device.

21. The computing system as recited in claim 20, wherein the browsing application further comprises:

a list of archived articles allowing retrieval of the parsed data associated with the selected page of any given archived article,

wherein when an archived article is selected when the browser is in an offline mode the parsed content is assembled allowing a user to view the selected page in a manner that is substantially similar to an online browsing experience.

22. The computing system as recited in claim 21, wherein when an identified other web page is selected by a navigation link embedded within the archived version of the selected page, the archived version of the other page is displayed only when the browsing application is in an offline state at the time of the selection.

23. The computing system as recited in claim 21, wherein when the browsing application switches from an online state to an offline state while displaying a page that has been previously archived, subsequent selection of another page associated with the same article results in the browsing application displaying an archived version of the selected other page.

24. The computing system as recited in claim 21, wherein the other pages identified by the DOM tree generator include other pages not having portions of the article directly associated with the selected web page but are only identified as related articles that a user reading the article might also be interest in.
