We are excited to inform the community of the recent announcement regarding the cooperation and collaboration between ASHRAE's BACnet Committee, Project Haystack and Brick Schema to provide a unified data semantic modeling solution to be adopted into BACnet.

As data interoperability becomes more important for applications of all types across the buildings market, the unification of semantic modeling is essential to enable data interoperability and reduce integration costs and effort. We are excited to be a part of this industry-wide effort which will benefit everyone from designers, constructors, owners, operators, systems integrators, product manufacturers and service providers.

This is an exciting initiative!

What is the roadmap/status/progress of this collaboration?

I agree with Jonas, it’s very interesting. Can we get visibility on the delivery schedul. Thanks in advance

As a start I would suggest reviewing three things:

• Haystack 4, which is the result of the collaboration work:
