Why not publish the FIX repository on GitHub? This way it would be easy to integrate as a submodule in projectes and to submit corrections as pull requests.
FIX Trading Community plans to publish FIX Latest in Orchestra schema, the successor to FIX Repository 2010 Edition. You can find a preview in GitHub here. The project contains FIX 4.2, 4.4, and 5.0SP2 baselines in Orchestra format. Orchestra specifications, examples, and demonstration code also reside in GitHub, all under organization name FIXTradingCommunity.
That’s great. Will be easy to contribute updated documentation then.
