I am currently trying to model IoT devices within buildings. I could start from scratch and develop the data model myself, but this seems like a common problem which will have been solved multiple times before. So I am looking to work from a standard.
I have found various examples including
AWS IoT Constructs https://docs.aws.amazon.com/thingsgraph/latest/ug/iot-tg-models-tdm-iot.html - models only part of the domain
Project Haystack https://project-haystack.dev/doc/index - lots of features but unsure how widely this is used
IEEE https://ieeexplore.ieee.org/document/8389334 - not sure this is relevant as it is behind a paywall
Is there a go-to data model standard that large parts of the IoT industry uses?
