Haystack tag dictionary
A smart tag dictionary (namespace) containing a collection
of tags developed by Project Haystack, which can be used for semantic
modeling of building control entities, i.e. site tags, building tags,
equipment tags, point tags, geo-location tags, etc.
The Haystack dictionary is indicated by the hs character, followed by a colon character (:).
The Haystack dictionary is a result of the work of the Open Source Initiative (OSI) hosted on the website http://project-haystack.org.
