We have posted the first official release of Haxall that we consider feature complete. Haxall provides a turnkey suite of software for integrating IoT protocols with the Haystack data model.

Key features:

• Reference implementation of haystack 4
• Def compiler used for the online defs and HTML documentation
• Folio database for storing/querying haystack data models
• Axon scripting language to manipulate Haystack data
• HTTP API implementation (both client and server)
• In-memory historization of point data
• Writable point priority array handling
• Connector framework
• Task engine for background processing of async data streams
• Integration with Docker to run external programs
• Integration with Python ML stack
• Simple Axon shell as the browser UI
• Suite of CLI tools including converters between zinc/trio/json/csv

Haxall includes a broad library of ready to use IoT protocols including:

• Haystack HTTP (both client and server)
• MQTT
• SQL (via JDBC)
• oBIX (both client and server)
• Sedona Sox
• Modbus (both TCP and RTU if you wire up serial APIs)
• Google Nest
• Ecobee

And the whole package is only 4 MB! The only requirement is a Java VM.

The setup steps show you how to load the example data sets from this site. You can use Haxall as a simple tool to quickly onboard and explore Haystack datasets.

This release includes a (mostly) complete set of documentation

Wow, this is awesome Brian! Thanks for sharing. It's been really cool watching this project take shape!
