Abstract

A system and method for providing namespace related information. A namespace library operating in a computer provides a central source of namespace related information for handling XML documents. The namespace related information may be used by other computer application programs operating in the computer. The namespace related information provided by the namespace library is indexed by namespace. Many types of namespace related information may be associated with each namespace. The computer application programs may obtain namespace related information by querying the namespace library using a particular namespace.

Claims

1. A computer-readable storage medium encoded with computer-executable components, comprising:

a namespace library configured to provide namespace related information to the computer-executable components on a computer, wherein the namespace related information is indexed by a plurality of namespaces, and wherein the namespace related information includes information that describes how an XML document is to be handled; and

an application program configured to open the XML document, wherein;

the XML document refers to at least one of the namespaces,

the application program is further configured to query the namespace library to identify namespace related information associated with the namespace,

the namespace related information is retrieved from the namespace library when an entry for the namespace exists in the namespace library,

the namespace related information is retrieved from a manifest collection that is identified in the namespace library when an entry for the namespace does not exist in the namespace library and when an entry for the namespace exists in the manifest collection,

the application program uses the namespace related information to open the XML document when namespace related information exists in the namespace library or the manifest collection,

the application program applies a universal solution associated with the application program to open the XML document when an entry for the namespace does not exist in the namespace library and the manifest collection; and

the application program opens the XML document without the namespace related information when an entry for the namespace does not exist in the namespace library and the manifest collection and no universal solution is associated with the application program.

2. The computer-readable medium of claim 1, wherein the namespace related information includes at least one location identifier for a primary XML schema associated with the namespace.

3. The computer-readable medium of claim 1, wherein the namespace related information includes at least one location identifier for a solution associated with the namespace and one of a plurality of application programs.

4. The computer-readable medium of claim 3, wherein the location identifier indicates a location on a local storage unit where the solution associated with the namespace is stored.

5. The computer-readable medium of claim 3, wherein the solution associated with the namespace is contained in a repository on another computer, and wherein the location of the solution in the repository is indicated by the location identifier.

6. The computer-readable medium of claim 5, wherein the application program associated with the solution associated with the namespace is configured to interact with the repository in the other computer through a network, and wherein the application program retrieves the solution associated with the namespace from the repository using the location identifier.

7. The computer-readable medium of claim 3, wherein the solution associated with the namespace includes an XML schema.

8. The computer-readable medium of claim 3, wherein the namespace related information further includes at least one property associated with the solution associated with the namespace.

9. The computer-readable medium of claim 1, wherein the namespace related information includes a location identifier for at least one manifest collection.

10. The computer-readable medium of claim 9, wherein the namespace related information further includes at least one property associated with the manifest collection.

11. The computer-readable medium of claim 1, wherein the namespace related information includes a location identifier of at least one default solution associated with the namespace and the application programs.

12. The computer-readable medium of claim 1, wherein the namespace related information includes a list of elements associated with the namespace.

13. The computer-readable medium of claim 12, wherein the namespace related information further includes at least one feature associated with one of the listed elements.

14. A method for obtaining information to handle an XML document containing a namespace, comprising:

querying a namespace library using the namespace;

when the namespace library contains an entry for the namespace, retrieving namespace related information associated with the namespace;

when the namespace library does not include an entry for the namespace and when an entry for the namespace exists in a manifest collection, retrieving the namespace related information from the manifest collection that is identified in the namespace library, wherein the namespace related information includes information that describes how the XML document is to be handled;

using the namespace related information to handle the XML document when namespace related information exists in the namespace library or the manifest collection;

if the namespace library does not contain at least one entry for the namespace in the namespace library and manifest collection, applying a universal solution associated with an application program to open the XML document; and

opening the XML document without the namespace related information when an entry for the namespace does not exist in the namespace library and the manifest collection and no universal solution is associated with the application program.

15. The method of claim 14, further comprising if the namespace library contains a location identifier for a solution associated with the namespace, retrieving the solution using the location identifier and applying the solution to open the XML document.

16. The method of claim 14, further comprising if the namespace library contains at least two location identifiers associated with two solutions associated with the namespace, prompting a user to select one of the solutions, retrieving the solution using the location identifier, and applying the selected solution to open the XML document.

17. The method of claim 14, further comprising installing the manifest collection.
