RE: Established vocabularies for units in RDF?

QUDT is the most mature project in this space.
However, it has been struggling with maintenance.

Subject: Established vocabularies for units in RDF?
I am wondering today what is the state of the art in terms of representing measurement units in RDF. I break this down into four layers:
(1) Measurement units regarded as basic, such as "meter", "degree centigrade"
(2) Measurement units in the abstract such as "length", "time"
(3) Measurement units created by the composition of basic units ("meters"/"seconds")
(4) So far we are representing measurement units in and of themselves, but (4) would including associating measurement units with properties in a schema and/or specific instance values.
What is out there to address this at the various levels?
