Abstract

The present invention provides a common namespace for Internet and local filesystem objects. In a preferred embodiment, the common namespaces constructed by first accessing a namespace definition table. The namespace definition table contains entries referencing both a filesystem namespace subtree definition module and an Internet namespace subtree definition module. The entry referencing the filesystem namespace subtree definition module is used to access the filesystem namespace subtree definition module in order to define a filesystem namespace subtree that encompasses filesystem addresses. Similarly, the entry referencing the Internet namespace subtree definition module is used to access the Internet namespace subtree definition module to define an Internet namespace subtree that encompasses Internet addresses. The defined filesystem and Internet namespace subtrees are then combined in order to assemble a namespace encompassing both filesystem addresses and Internet addresses.

wherein the parse, bind, and display methods are universal methods accessible by one or more application programs.

12. The method of claim 11, wherein the steps of invoking are performed by a web browser application program.

13. The method of claim 11, wherein the step of invoking a parse method uses a shell extension table to identify the location and the format of the data corresponding to the received address.

14. The method of claim 13, wherein the shell extension table includes a “

my computer”

subtee and an “

internet”

subtree.

15. The method of claim 11, wherein the step of invoking a bind method includes the step of retrieving the data synchronously.

16. The method of claim 11, wherein the step of invoking a bind method includes the step of retrieving the data asynchronously.

17. The method of claim 11, wherein the step of invoking a display method includes the step of invoking the display method corresponding to web page data.

18. The method of claim 11, wherein the step of invoking a display method includes the step of invoking the display method corresponding to local filesystem data.

19. The method of claim 11, wherein the step of invoking a display method includes the step of invoking the display method corresponding to text document data.

20. The method of claim 11, wherein the step of invoking a display method includes the step of invoking the display method corresponding to word processing document data.

21. The method of claim 11, wherein the step of invoking a display method includes the step of invoking the display method corresponding to spreadsheet document data.

22. The method of claim 11, wherein the step of invoking a display method includes the step of displaying contents on-the-fly as they are received.

23. A computer-readable medium whose contents cause a computer system to retrieve and display arbitrary content stored in an arbitrary location by performing the steps of:

under control of a single system component accessible by one or more application programs,

(a) receiving a name corresponding to data;

(b) invoking a parse method to resolve the received name thereby identifying a location corresponding to the received name;

(c) retrieving data from the location, wherein the location may be either the computer system or a computer system located over the Internet, and wherein the data may be one of a plurality of formats; and

(d) submitting the retrieved data to a universal data display module for display;

under control of a universal data display module,

(a) identifying a format of the retrieved data;

(b) identifying a display routine within the universal data display module capable of displaying data of the identified format; and

(c) invoking the display routine to display the retrieved data.

24. The computer-readable medium of claim 23, wherein the step of identifying a format identifies the retrieved data as a web page.

25. The computer-readable medium of claim 23, wherein the step of identifying a format identifies the retrieved data as a local filesystem file.
