Abstract

A system and method of integrating the physical and virtual namespaces of a site into a single hierarchical representation thereof that reflects the hierarchical arrangement of the site as perceived by the client. A dynamic namespace integration mechanism is implemented as a part of a site management service to look up and integrate hierarchically organized directory information maintained in a registry (e.g., metabase) for both physical and virtual directories. The administrator is then given a view of the site that corresponds to the view of the client browsing the site. The administrator may interface with a user interface displaying the integrated namespace to manage the properties under a site'"'"'s directories. The hierarchical relationships between the physical and virtual directories enable the administrator to set properties on parent nodes that are inheritable by child nodes, simplifying management tasks.

Claims

1. In a computer system, a method of representing a site having a hierarchical organization as perceived by a client, comprising:

looking up first namespace information representing vitual directories of the site, the virtual directories having alias mappings that map the namespace information of the virtual directories to their physical locations, looking up second namespace information representing physical directories of the site, and integrating the first and second namespace information into an integrated namespace that is hierarchically organized to reflect the hierarchical organization of the site as perceived by the client and to enable information to be automatically propagated across the virtual and physical directories based on the hierarchical organization of the integrated namespace.

2. The method of claim 1 wherein the integrated namespace comprises a hierarchical representation of the directories of the site.

3. The method of claim 1 wherein the virtual directories are represented by an alias in the integrated namespace.

4. The method of claim 1 wherein the step of looking up first namespace information comprises:

accessing a registry.

5. The method of claim 4 wherein the registry is a metabase including properties under the directories.

6. The method of claim 1 further comprising:

displaying the integrated namespace in a user interface.

7. The method of claim 6 further comprising:

receiving user input via the user interface, displaying a property sheet in response to the user input, receiving additional user input corresponding to a property setting, and recording the property setting.

8. The method of claim 7 wherein recording the property setting comprises storing the property setting in a metabase.

9. The method of claim 6 further comprising:

receiving user input via the user interface corresponding to an enumeration request of a selected directory, looking up at least one child directory hierarchically below the selected directory, and displaying the at least one child directory on the user interface.

10. The method of claim 6 further comprising:

receiving user input via the user interface corresponding to a selected directory, displaying a property sheet in response to the user input, receiving additional user input on the property sheet corresponding to a property setting, and wherein the information is automatically propagated across the virtual and physical directories based on the hierarchical organization of the integrated namespace by recording the property setting in a registry under the selected directory and at least one child directory thereof such that the child directory inherits the property setting.

27. The method of claim 1 wherein one of the virtual directories has a name that collides with a name of one of the physical directories, and wherein integrating the first and second namespace information into the integrated namespace includes selecting the viral directory name for inclusion into the integrated namespace.

28. The method of claim 1 wherein integrating the first and second namespace information into the integrated namespace includes locating in the metabase virtual and physical directories having at least one property explicitly set, and searching for physical directories having no property explicitly set.

11. In a computer system, a system for providing a representation of a site having a hierarchical organization as perceived by a client, comprising, a virtual namespace including virtual directory information of the site, a physical namespace including physical directory information of the site, a dynamic namespace integrator configured to integrate the virtual namespace and the physical namespace into an integrated namespace that is hierarchically organized to reflect the hierarchical organization of the site as perceived by the client, and a user interface for displaying the integrated namespace and configured to enable information to be automatically propagated across the virtual and physical directories based on the hierarchical organizing of the integrated namespace.

12. The system of claim 11 wherein the dynamic namespace integrator integrates the virtual namespace and the physical namespace into a hierarchical representation of the directories of the site.

13. The system of claim 11 further comprising a map of virtual directories to aliases representative thereof, and wherein each of the virtual directories are represented by an alias in the integrated namespace.

14. The system of claim 11 further comprising a registry for maintaining the virtual namespace.

15. The system of claim 14 wherein the registry is a metabase including properties under the directories.

16. The system of claim 11 further comprising a mechanism for detecting user input at the user interface.

17. The system of claim 16 wherein the user interface displays a property sheet in response to user input corresponding to a selected directory.

18. The system of claim 17 wherein the mechanism for detecting user input at the user interface detects the setting of a property on the property sheet.

19. The system of claim 18 further comprising a mechanism connected to the user interface and configured to store a property setting corresponding to the detected property setting in the selected directory and at least one child directory thereof, such that at least one child directory inherits the property setting.

20. The system of claim 16 wherein the mechanism for detecting user input at the user interface detects a user request to enumerate a selected directory, and wherein the dynamic namespace integrator looks up at least one child directory hierarchically below the selected directory in response to the request.

29. The system of claim 11 wherein the dynamic namespace integrator detects name collisions between physical and virtual directory names and integrates the first and second namespace information by selecting the virtual directory name upon detection of a name collision.

30. The system of claim 11 further comprising a metabase, and wherein the dynamic namespace integrator integrates the first and second namespace information by locating virtual and physical directories having at least one property explicitly set in the metabase, and searching for directories having no property explicitly set.

21. A computer-readable medium having computer-executable instructions, comprising:

providing a physical namespace representing physical directories of a site, the site having a a hierarchical organization as perceived by a client;

providing a virtual namespace representing virtual directories of the site, at least one virtual directory being mapped to a physical directory of the site by an alias;

integrating the virtual namespace and the physical namespace into a hierarchical representation of the directories of the site that matches the hierarchical organization as perceived by the client; and

automatically propagating information across the virtual and physical directories based on the hierarchical organization of the integrated namespace.

22. The computer-readable medium of claim 21, further comprising:

changing the mapping between the alias and the physical location of the virtual directory in response to moving the virtual directory to another physical location.

23. The computer-readable medium of claim 21, further comprising:

receiving input via a user interface,

displaying a property sheet in response to the input,

receiving additional input corresponding to a property setting, and

recording the property setting.

24. The computer-readable medium of claim 23, wherein recording the property setting comprises storing the property setting in a metabase.

25. The computer-readable medium of claim 24, wherein the metabase comprises a registry.

26. The computer-readable medium of claim 21, further comprising:

receiving input via a user interface corresponding to an enumeration request of a selected directory,

looking up at least one child directory hierarchically below the selected directory, and

displaying the at least one child directory on the user interface.
