Abstract

Claims (35)

1. A system for connecting a client computing device to multiple data sources, the system comprising:

a first data source associated with a first communication channel for delivering a process virtual machine to the client computing device;

a second data source associated with a second communication channel; and

a client computing device configured to:

instantiate the first communication channel to mount a virtual drive representing the first data source on the client computing device; and

initiate execution of at least one application on the process virtual machine, the application configured to cause the second communication channel to be instantiated to mount a virtual drive representing the second data source on the client computing device;

wherein the second data source is a folder tree, and wherein mounting the virtual drive representing the second data source includes receiving an extensible markup language (XML) document representing the folder tree that is created by:

querying a folder database for information associated with a root folder of the folder tree;

authenticating that a user has rights to access the root folder;

adding metadata associated with the root folder to the XML document; and

for each subfolder within the hierarchy of the root folder:

in response to determining that the subfolder has the same permissions with respect to the user as the root folder:

obtaining folder metadata of the subfolder; and

adding metadata associated with the subfolder to the XML document; and

in response to determining that the subfolder has different permissions with respect to the user as the root folder:

adding an XLink that references the subfolder to the XML document.

2. The system as recited in claim 1 , wherein the first data source is a network file system accessible from the Internet and the second data source is a file system provided from a private network.

3. The system as recited in claim 1 , wherein a data source that is mounted as a virtual drive is one selected from the group of a local storage device, a network file system, and a shared group folder.

4. The system as recited in claim 1 , wherein at least one file in the root folder is of a file type that initiates execution of an application upon the root folder being mounted as a virtual drive on the client computing device.

5. The system as recited in claim 1 , wherein the first and second communication channels are created in accordance with a communicator Application Programming Interface that accepts logic for accessing data from a data source and translating the data into an XML format expected by an executing application.

6. The system as recited in claim 1 , wherein applications executed by the process virtual machine accesses a model document to implement application functionality without interacting directly with a data source that is managed by a communication channel.

7. A computer-implemented method of generating a document for transmission to a computing device to enable the computing device to mount a virtual drive representing a folder tree, the method comprising:

querying, by a computing device, a folder database for information associated with a root folder of the folder tree;

authenticating that a user has rights to access the root folder;

adding metadata associated with the root folder to the document; and

for each subfolder within the hierarchy of the root folder:

in response to determining that the subfolder has the same permissions with respect to the user as the root folder:

obtaining folder metadata of the subfolder; and

adding metadata associated with the subfolder to the document; and

in response to determining that the subfolder has different permissions with respect to the user as the root folder:

adding an XLink that references the subfolder to the document.

8. The method of claim 7 , wherein the document is an extensible markup language (XML) document.

9. The method of claim 7 , further comprising receiving a request from a client device, the request including a uniform resource locator (URL) that identifies the root folder.

10. The method of claim 9 , wherein the uniform resource locator (URL) includes a folder identifier that uniquely identifies the root folder.

11. The method of claim 10 , wherein the folder identifier includes information usable to indicate a location of the folder database.
