[Suggestion] Semantic annotation of workflows

[jan-janssen]

@samwaseda developed a semantic annotation package named semantikon which provides the option to include semantic annotations in the workflow definition, especially in terms of units for physical quantities. This could be a great extension for the Python Workflow Definition:

>>> from semantikon.typing import u
>>> from rdflib import Namespace
>>>
>>> EX = Namespace("http://example.org/")
>>> 
>>> def get_speed(
...     distance: u(float, units="meter", uri=EX.distance),
...     time: u(float, units="second", uri=EX.time),
... ) -> u(float, units="meter/second", label="speed", uri=EX.speed):
...     return distance / time
