Abstract

Methods, systems, and products are disclosed for referencing message elements in an application message in a messaging environment that include: establishing a message model on a computer, the message model comprising message element specifications that each specify a message element for storing data in the application messages, each message element specification comprising element characteristics; creating, by a messaging module on the computer in dependence upon the message model, a message element designator map that maps a separate message element designator to each message element specified by the message model; receiving, in the messaging module from a requesting module, a request for an element designator for a specific message element identified by the element characteristics for the specific message element; and providing, by the messaging module to the requesting module, the requested element designator in dependence upon the message element designator map and the element characteristics for the specific message element.

creating, by a messaging module on the computer in dependence upon the message model, a message element designator map, the message element designator map mapping a separate message element designator to each message element specified by the message model, wherein each message element is specified in the message element designator map by the element characteristics of the message element specified in the message model including the element name of the message element;

receiving, in the messaging module from a requesting module, a request for an element designator for a specific message element, the specific message element identified in the request by the element characteristics for the specific message element; and

providing, by the messaging module to the requesting module, the requested element designator in dependence upon the message element designator map and the element characteristics for the specific message element.

2. The method of claim 1 further comprising:

receiving, by the messaging module from the requesting module, a request for a value for the specific message element in an application message, the specific message element identified in the request for the value by the requested element designator; and

providing, by the messaging module to the requesting module, the value for the specific message element in dependence upon the application message, the requested element designator, and the message element designator map.

3. The method of claim 1 further comprising:

receiving, by the messaging module from the requesting module, a request to store a value for the specific message element in an application message, the specific message element identified in the request to store the value by the requested element designator; and

storing, by the messaging module, the value for the specific message element in the application message in dependence upon the requested element designator and the message element designator map.

4. The method of claim 1 further comprising:

receiving, by the messaging module from the requesting module, a request for the element characteristics for the specific message element, the specific message element identified in the request for the element characteristics by the requested element designator; and

providing, by the messaging module to the requesting module, the requested element characteristics for the specific message element in dependence upon the requested element designator and the message element designator map.

5. The method of claim 1 wherein:

the specific message element is further identified in the request by an element designator for a parent message element; and

providing, by the messaging module to the requesting module, the requested element designator in dependence upon the message element designator map and the element characteristics for the specific message element further comprising providing the requested element designator in dependence upon the message element designator map, the element characteristics for the specific message element, and the element designator for the parent message element.

6. The method of claim 1 wherein the element characteristics comprise an element name.

7. The method of claim 1 wherein the computer is a subscribing client device, the method further comprising brokering, by a stream administration server, establishment of a message stream from a feed adapter to the subscribing client device, the message stream providing the application messages from the feed adapter to the subscribing client device.

8. The method of claim 1 wherein the messaging environment is a financial market data environment and wherein the application messages comprise financial market data.

9.

establishing a message model on a computer, the message model specifying a message format for interpreting application messages, the message model comprising one or more message element specifications, each message element specification specifying a message element for storing data in the application messages, each message element specification comprising element characteristics that include an element name;

creating, by a messaging module on the computer in dependence upon the message model, a message element designator map, the message element designator map mapping a separate message element designator to each message element specified by the message model, wherein each message element is specified in the message element designator map by the element characteristics of the message element specified in the message model including the element name of the message element;

receiving, in the messaging module from a requesting module, a request for an element designator for a specific message element, the specific message element identified in the request by the element characteristics for the specific message element; and

providing, by the messaging module to the requesting module, the requested element designator in dependence upon the message element designator map and the element characteristics for the specific message element.

10. The system of claim 9 further comprising computer program instructions capable of:

receiving, by the messaging module from the requesting module, a request for a value for the specific message element in an application message, the specific message element identified in the request for the value by the requested element designator; and

providing, by the messaging module to the requesting module, the value for the specific message element in dependence upon the application message, the requested element designator, and the message element designator map.

11. The system of claim 9 further comprising computer program instructions capable of:

receiving, by the messaging module from the requesting module, a request to store a value for the specific message element in an application message, the specific message element identified in the request to store the value by the requested element designator; and

storing, by the messaging module, the value for the specific message element in the application message in dependence upon the requested element designator and the message element designator map.

12. The system of claim 9 further comprising computer program instructions capable of:
