Determine / document recommended usage of available mutable DID metadata fields
The following mutable DID metadata fields are available for subscription management and can be populated during registration:
events = int
guid = str
project = str
datatype = str
run_number = int
stream_name = str
prod_step = str
version = str
campaign = str
task_id = int
panda_id = int
lumiblocknr = int
provenance = str # 2 character limit
phys_group = str
Document a recommended scheme for use of these fields.
E.g.
- project: experiment name, "LIGO, Virgo" etc
- campaign: observing run, "O3, O4" etc (can't use
run_number
as its an int and we don't control the types)
