Project Haystack is excited to announce an important new resource, part of the new Haystack 4 Developers website (https://project-haystack.dev), called Examples (https://project-haystack.dev/example).
This resource of Examples, addresses requests from many members of the community to have access to actual examples of fully-tagged Haystack projects.
Three different contributors from the Haystack community donated anonymized datasets of fully-tagged, real-world site projects. The models include steam, hot water, and chilled water plants along with AHU, FCU, and VAV air systems. All 3 are mostly Energy/HVAC focused sites. The sites are generically named using the phonetic alphabet.
Visitors to the Haystack 4 Examples page can browse these datasets on the website and follow links between all their ref relationships. Plus, each site can be downloaded via one of the standard Haystack formats: Zinc, JSON, Trio, Turtle, JSON-LD, or CSV.
We are hoping that these public datasets will aid users in getting started with Haystack 4 and spur the following:
- Inspire others to donate their building models. (Just let us know!)
- Public review to determine if these are "good" reference models.
- Analysis for where custom tags were used (which were left in the datasets using a special custom tag) to see where Haystack can be enhanced. (Note that obvious vendor-specific tags are not included.)
- Datasets you can download and use to test code such as Zinc parsers, Machine Learning-based naming algorithms, RDF tools, etc.
- Accelerate the work to build out "equip/device templates". The infrastructure to display Haystack data in a browser with cross-referencing to defs/other entities is ideal for use when we are ready to add predefined "equip/device templates".
Thank you to the community members that donated their Haystack project databases.
