Abstract

Systems and methods for processing documents are disclosed. Documents received at a data server are transcoded using locally stored or generated code books. Code books for transcoded documents received at a wireless mobile communication device are either retrieved from a memory on the device or requested from a data server. In response to a code book request, a data server retrieves a requested code book from a local memory or generates the requested code book and returns the requested code book to a requester. A wireless mobile communication device may also generate and transcode XML documents using a locally stored code book, a locally generated code book, or a code book received in response to a code book request.

Claims

1. A system of processing extensible markup language (XML) documents, comprising:

a code book system configured to receive code book requests and to provide a code book responsive to each code book request;

a memory in the code book system configured to store code books;

a transcoder system configured to receive XML documents, and, for each received XML document, to request a corresponding code book from the code book system and to use the code book to transcode the received XML document; and

a code book builder configured to generate code books,

wherein the code book system is further configured to determine whether a requested code book is stored in the memory, and to initiate the code book builder to build the requested code book and to receive the requested code book from the code book builder where the requested code book is not stored in the memory.

2. The system of claim 1, further comprising a connection handler configured to receive documents from an information source and to provide the documents to the transcoder system.

3. The system of claim 2, wherein the connection handler is further configured to receive transcoded documents from the transcoder system, and to send the transcoded documents to a wireless mobile communication device via a wireless transport.

4. The system of claim 3, wherein the connection handler is further configured to receive connection requests from the wireless mobile communication device via the wireless transport, and wherein the documents are requested from the information source responsive to the connection requests.

5. The system of claim 4, further comprising a protocol translator configured to convert the connection requests from a first protocol associated with the wireless transport to a second protocol associated with the connection handler and the information source.

6. The system of claim 1, further comprising a code book servlet which receives code book requests for code books from a wireless mobile communication device via a wireless transport, requests the code book from the code book system, and returns the requested code books to the wireless mobile communication device via the wireless transport.

7. The system of claim 1, wherein the code book builder is further configured to retrieve a document definition for a received document and to generate a code book based on the document definition when the code book system initiates the code book builder.

8. The system of claim 7, wherein the code book system is further configured to determine a document identifier associated with the document definition of a received document and to provide the document identifier to the code book builder where the requested code book is not stored in the memory.

9. The system of claim 8, wherein the document identifier is a resource address from which the document definition is available.

10. The system of claim 7, wherein the document definition is embedded in the received document and extracted from the received document.

11. The system of claim 1, wherein the code book system is further configured to store code books generated by the code book builder to the memory.

12. A system of providing a extensible markup language (XML) code book in response to a XML code book request, comprising:

a receiver configured to receive a code book request from a requestor, the code book request identifying a requested code book;

a XML code book cache storing a plurality of code books;

a XML code book system configured to determine whether the requested code book is stored in the code book cache;

a XML code book builder configured to generate the requested code book and to store the requested code book in the code book cache where the requested code book is not stored in the code book cache; and

a transmitter configured to transmit the requested code book to the requestor.

13. The system of claim 12, wherein the code book request comprises a document type identifier to identify the requested code book, and wherein the code book builder is further configured to retrieve a document definition corresponding to the document type identifier and to generate the requested code book using the document definition.

14. The system of claim 13, further comprising a connection handler for receiving a document definition request from the code book builder, retrieving the document definition from a document definition source, and returning the document definition to the code book builder.

15. The system of claim 14, wherein the document definition source is a document type definition (DTD) server.

16. The system of claim 12, wherein the receiver and the transmitter comprise a code book servlet.

17. The system of claim 12, implemented in a data server.

18. The system of claim 12, implemented in a wireless mobile communication device.
