Schema-based dynamic parse/build engine for parsing multi-format messages
First Claim
1. A computer-implemented method comprising:
- receiving an output message from a server computer, wherein the output message comprises a plurality of fields, and wherein the server computer;
determined a schema for the output message;
retrieved a plurality of handlers based on the schema, each handler being code for building at least one field of the plurality of fields of the output message from a common internal message format object, each of the plurality of handlers being separately compiled; and
translated the common internal message format object into the output message using the plurality of handlers.

Abstract
A parse/build engine that can handle multi-format financial messages. The engine converts the different format messages into a common format, and the common format message is then processed by the business service application. A parser examines the message and determines an appropriate schema for the particular format of message received. The schema is a data structure in a schema registry that includes a grammar structure for the received format as well as pointers to handlers for converting the different fields of the message into the internal message format using the grammar structure (the “grammar” can include field sequence, field type, length, character encoding, optional and required fields, etc.). The handlers are individually compiled. As formats change, new formats or changes to old formats can be dynamically added to the parse/build engine by loading new schema and handlers.
