In CoL we want to exchange species estimates for taxa, i.e. number of estimated species according to some reference. The estimation could be for all described species including/excluding fossils or estimated species including so far undescribed species. In theory several estimations per taxon could exist if they are based on different references.
Sharing this in ColDP we have 2 main options:
simple addition of speciesEstimate and speciesEstimateReferenceID to the taxon table with fixed semantics for the estimate, e.g. living and fossil described species.
addition of a new estimate entity that links to a taxon and reference and has a type and species estimate:
taxonID
referenceID
estimate (number of species)
type (living described, fossil described, all described, undescribed)
