Automatic transformation of messages between service versions

A system for automatic transformation of messages between service versions, comprising:

• a computer system including one or more computer processors, one or more computer-readable storage media, and program instructions stored on one or more of the computer-readable storage media for execution by at least one of the one or more processors;
• a service identifying component and a message collecting component for identifying and collecting message data, respectively, of messages sent to two or more versions of a service, using a proxy system, and storing the collected message data in a historical message data store using the proxy system;
• a transformation rule generator for transforming a message of the messages using message transformation rules generated based on the collected message data in the historical message data store, the message transformation rules for transforming a message format for an earlier version of the service to a message format for a later version of the service, using the proxy system, the transforming the message being in response to identifying, using the proxy system, the message being for the earlier version of the service and there being the later version of the service, and the transformed message being forwardable to the later version of the service, using the proxy system;
• wherein the service identifying component identifies the message data as relating to a version of a service;
• and the system further comprising:
• a message data interrogating component for inferring relationships between structure and content of the messages sent to different versions of a service;
• the transformation rule generator creating the message transformation rules based on the inferred relationships;
• the proxy system including a message intercepting component for receiving the message for the version of the service, using the proxy system;
• and
• the proxy system including a transformation rule applying component for transforming the message format for the earlier version of the service to the message format for the later version of the service.

A computer program product for automatic transformation of messages between service versions, the computer program product comprising a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code executable by a computer to perform a method comprising:

• identifying and collecting message data of messages sent to two or more versions of a service, using a proxy system, and storing the collected message data in a historical message data store using the proxy system;
• transforming a message of the messages using message transformation rules generated based on the collected message data in the historical message data store, the message transformation rules for transforming a message format for an earlier version of the service to a message format for a later version of the service, using the proxy system, the transforming the message being in response to identifying, using the proxy system, the message being for the earlier version of the service and there being the later version of the service;
• forwarding the transformed message to the later version of the service, using the proxy system:,
• identifying the message data as relating to a version of a service;
• inferring relationships between structure and content of the messages sent to different versions of a service;
• creating the message transformation rules based on the inferred relationships, the message transformation rules being for transforming the message format for the earlier version of the service to the message format for the later version of the service;
• and
• receiving the message for the version of the service, using the proxy system.
