Innovations in Comfort, Efficiency, and Safety Solutions.
AB: John, SkyFoundry made a
significant announcement recently regarding open sourcing core SkyFoundry
software technology. Can you tell us about the initiative you are calling
JP: We are excited
to share details about this announcement. Haxall is SkyFoundry’s new initiative
that open sources many of SkySpark’s core software modules. We believe
that open sourcing these proven software components will streamline development
and reduce the cost of creating IoT devices for the built environment (BIoT), directly
helping to accelerate the transition to data-driven, intelligent buildings.
product developers can use Haxall to dramatically
streamline the process of building IoT data products—both hardware and software.
It includes a core subset of proven SkyFoundry code that addresses critical
functions needed to connect to devices and equipment systems, normalizes their
data, and makes it openly available in a standardized format to other value-added
streamlines the onboarding of data into value-added applications by providing
the software functions to communicate with external devices and capture
semantic tagging at the edge. And, importantly, Haxall provides a
powerful framework to run sophisticated software applications at the
edge. It can also be used as an edge gateway to integrate IoT device data
up to cloud-based applications. In those applications Haxall
delivers fully modeled data to applications, dramatically reducing work effort
AB: Can you tell us more about what Haxall
JP: It starts with full support for Haystack
4. Haxall is bundled with SkySpark's full suite of Haystack APIs. This
includes a rich set of APIs to model, encode, and query data using the Haystack
Next, it includes SkySpark's
revolutionary Folio database technology. Folio is built 100% around
the Project Haystack data modeling standard. Everything is stored as
native Haystack dicts and queried using Haystack filters. Folio provides
seamless integration with persistent and transient real-time tags, making
it a truly unique design to build IoT applications.
Haxall also includes the highly
efficient Axon scripting engine. This allows you to create scripts to do
things like onboard, query, and transform your Haystack data using a rich
library that includes hundreds of functions. The Axon function library
has been leveraged for over a decade to streamline working with device data.
Then there is the Haxall Daemon, a
complete runtime that is provided to quickly get your IoT applications up and
running. The Haxall Daemon comes with "batteries included"—it has
tools to create new databases, built-in user management and authentication, a webserver
with full support for the Haystack HTTP API, dynamic module management, and an
Axon shell for remote management. And, it provides runtime support for both the
Communicating with external devices
and systems is key to IoT applications and Haxall includes a connector
framework to acquire data from external devices and normalize diverse IoT
protocols into the Haxall ecosystem. It also offers a suite of ready-to-use
connectors provided open source including Haystack HTTP API, MQTT, Modbus,
oBIX, SQL, and Sedona Sox. In addition, Haxall includes an Arcbeam™ module
that provides seamless connection of Haxall devices into SkyFoundry’s SkySpark
software. Plus, an in-memory trending engine is included to historize
connector data into time-series data.
AB: You mentioned that the goal of
Haxall is to accelerate development of the BIoT, can you tell us more about
JP: At SkyFoundry, we have seen that one of the major barriers to scaling the benefits the IoT can bring to buildings is the challenge of acquiring and modeling device data. Haxall streamlines development and reduces the cost of building IoT data acquisition devices by providing proven software components needed to build IoT edge data acquisition solutions. And, Haxall is available as open source under the widely adopted Academic Free License ("AFL") v. 3.0. There is no cost or business relationship required to use it. https://opensource.org/licenses/AFL-3.0
AB: What is the availability of Haxall
and where can our readers learn more?
JP: The majority of Haxall is available now. Some of the connectors will be released over the summer..
The code for Haxall’s software modules
are available on GitHub. Those modules include:
