Application and file system hosting framework
First Claim
1. A system for hosting an XML file system, the system comprising:
- an XML web service for two-way communication with a client computing device;
a message server for transmitting data updates from the XML file system to the client computing device;
a file server for storing raw data files;
a folder database for storing folder hierarchy information; and
an index server for accessing and indexing the raw data files on the file server and the folder hierarchy information in the folder database and storing full-text indexes of the raw data files and the folder hierarchy information;
wherein the XML Web service is configured to construct a document describing a folder tree, including obtaining folder metadata associated with a root folder from the folder database, obtaining metadata describing each file in the root folder from the index server, and inserting the folder and file metadata corresponding to the root folder into the document;
wherein to construct a document describing a folder tree further includes;
for each subfolder having the same permissions with respect to a user as the root folder, obtaining folder metadata associated with the subfolder from the folder database, obtaining metadata describing each file in the subfolder folder from the index server, and inserting the folder and file metadata corresponding to the subfolder into the document; and
for each subfolder having different permissions with respect to the user as the root folder, inserting an XLink corresponding to the subfolder into the document, the XLink allowing a user to access the subfolder once the user'"'"'s right to access the subfolder is authenticated.

Abstract
Generally described, the present invention is directed to a network operating system that provides more effective ways of leveraging the connectivity of computer networks. In one embodiment, an XML virtual machine is implemented that accepts high-level application code written in an XML programming language as input. Functionality is provided to interpret or translate the application code written in an XML programming language into code that is suitable for execution across computer platforms. Moreover, the XML virtual machine supports the Model View Controller (MVC) design paradigm that facilitates true data abstraction from applications to a common data model. Multi-instance applications, with each instance potentially supporting multiple views, may be created and executed.
