Steve and I used `Token' as the class name for anything that provides
evidence of a dwc:Occurrence. The Token could be an image, a dried
specimen, or...

... an Observation. I see a literature citation as documentation of an
Observation, which provides evidence for an occurrence. If we wanted to
integrate Darwin-SW, or even DwC with existing observational ontologies
(e.g. OBOE, https://semtools.ecoinformatics.org/oboe), we could allow an
oboe:Observation to also be a Token, providing evidence for a
dwc:Occurrence.
Please see the discussion of Token at:
