Project Haystack standardizes semantic data models and web services with the goal of making it easier to unlock value from the vast quantity of data being generated by the smart devices that permeate our homes, buildings, factories, and cities. Applications include automation, control, energy, HVAC, lighting, and other environmental systems.
Project Haystack encompasses the entire value chain of building systems and related intelligent devices. Owners and consultants can specify that Haystack conventions are used in their building automation systems to ensure cost effective analytics and management of their buildings for years to come.
System integrators and manufacturers who integrate Haystack support into their projects and products are better positioned for the future of providing value-added services.
Project Haystack is a 501C tax-exempt non-stock corporation formed May 28, 2014 under the provisions of Chapter 10 of Title 13.1 of the Code of Virginia of 1950. All work developed by the project-haystack.org community is provided for use as open source software.
