This project contains resources and sample code for FIX Orchestra version 1.1. Technical specifications for FIX Orchestra are in project fix-orchestra-spec.
FIX Orchestra is intended to provide a standard and some reference implementation for machine readable rules of engagement between counterparties. The goal is to reduce the time to get counterparties trading, and improve accuracy of implementations.
See Orchestra tutorials and FAQ.

Orchestrations public Orchestra files for service offerings
FIX Standards normative standards documents
Orchestra version 1.0 Draft Standard was promoted to Technical Standard with minor enhancements and corrections on February 17, 2021. Version 1.6.10 of this project conforms to Orchestra version 1.0 Techncial Standard.
The following modules are normative.
This module contains an XML schema for Orchestra. It is used to convey message structures and their components, as well as FIX application behaviors. Users may express workflow as responses to messages under different scenarios, as well as external state information that may influence behaviors.
In addition to providing the XML schema as a resource, the module builds Java bindings for the schema.
This module provides an XML schema for service offerings, protocols and session provisioning. In addition to providing the XML schema as a resource, the module builds Java bindings for the schema. Service elements may link to Orchestra files composed in the repository schema.
An orchestra file may contain conditional expressions to describe conditionally required fields and tell when a certain response to a message applies. Also, the DSL may be used for assignment expressions to set message fields and external state variables.
The Score grammar is provided in the notation of ANTLR4, and the project builds a lexer/parser for the grammar. This project generates Java code, but ANTLR4 is capable of generating several other programming languages from the same grammar.
Repository 2010 Edition was the version of the FIX Repository prior to FIX Orchestra. This module provides a parser for its XML schema. It may be used to process existing Repository files and to convert their message structures to Orchestra format.
This utility generates documentation for an Orchestra file that can be view in any web browser. The output of the generator may be used locally or from a web server.
This module contains RepositoryValidator to validate that a file conforms to the repository schema. Also, RepositoryCompressor extracts slices of a repository file. An XSLT is provided to translate existing Repository 2010 Edition files to the Orchestra schema.
This module contains InterfacesValidator to validate that a file conforms to the interfaces schema.
Experimental modules have been moved to GitHub repository fix-orchestra-experimental
This following modules are experimental. Requirements are still being gathered and discussed by the FIX Orchestra working group. Participation in the working group is encouraged by FIX Trading Community members, and more broadly, feedback is welcome from interested GitHub users.
A demonstration of state machine code generation from an Orchestra file.
This module is a demonstration of acceptance test generation from an Orchestra file using Behavior Driven Design (BDD) concepts.
This utility has been moved to repository FIXTradingCommunity/fix-sbe-utilities. It creates a Simple Binary Encoding message schema from an Orchestra file.
See repository FIXTradingCommunity/fix-orchestra-protobuf for utilities to generate Google Protocol Buffers schemas from an Orchestra file.
Modules specific to QuickFIX have been moved to repository fix-orchestra-quickfix. Some models in this project are intended to be operational while others are proofs of concept.
This module generates a QuickFIX data dictionary from an Orchestra file. The format can be consumed by the C++, Java and .NET versions. Additionally, the module generates message classes for QuickFIX/J directly from an Orchestra file. Although the QuickFIX data dictionary format is not as richly featured as Orchestra, it is hoped that this utility will help with Orchestra adoption.
This module generates code that is conformant to the QuickFIX/J API for validating and populating messages. It is dependent on repository-quickfix.
A demonstration of session configuration for QuickFIX open-source FIX engine. It consumes an XML file in the interfaces schema.

Data files in this project under test/resources are strictly for testing and to serve as examples for format. They are non-normative for FIX standards and may not be up to date.
The project is built with Maven version 3.3 or later.
This project requires Java 11 or later. It should run on any platform for which a JVM is supported. Some modules use Java Platform Module System (JPMS).
Several open-source JDK implementations are available, including Eclipse Temurin and Azul Zulu.
