Abstract

The virtual file system is described that enables both real data resources, such as a content file, and virtual data resources, such as a field within a database or a state determined by a mark-up language element, to be accessed through a single root.

Claims

1. A device comprising a storage means for storing a plurality of data resources, a file system for organizing the plurality of data resources stored in the storage means and a user interface for providing user access to the plurality of data resources, wherein the file system comprises one or more locations comprising directly addressable data resources and one or more locations comprising indirectly addressable data resources, the indirectly addressable data resources being accessible through a data provider, the file system being configured, in use, to provide a single interface from the user interface to both directly addressable data resources and indirectly addressable data resources.

2. A device according to claim 1, wherein the directly addressable data resources comprise data content files which, in use, are displayed within the user interface.

3. A device according to claim 1 or claim 2, wherein the indirectly addressable data resources comprise a database and, in use, the result of one or more queries is displayed within the user interface.

4. A device according to claim 1 or claim 2, wherein the indirectly addressable data resources comprise a mark-up language element and, in use, the mark-up language element is rendered and the associated result is displayed within the user interface.

5. A method of for storing a plurality of data resources within a file system of a device, the method comprising the steps of:

defining one or more locations comprising one directly addressable data resources;

defining one or more locations comprising indirectly addressable data resources, the indirectly addressable data resources being accessible through a data provider;

wherein file system provides a single interface from the user interface to access both the directly addressable data resources and indirectly addressable data resources access.

6. A method according to claim 5, wherein the method comprises the further step of accessing a directly addressable data resource such that the content of the data resource is displayed within the user interface.

7. A method according to claim 5, wherein the method comprises the further step of accessing an indirectly addressable data resource, the data resource comprising a database such that the result(s) of a database query is displayed within the user interface.

8. A method according to claim 5, wherein the method comprises the further step of accessing an indirectly addressable data resource, the data resource comprising a mark-up language element such that the mark-up language element is rendered and the associated result is displayed within the user interface.

9. A data carrier comprising computer executable code for performing the method of any of claims 5 to 8.
