acceptedKey (checklist) vs acceptedTaxonKey (occurrence) don't follow same strategy

[damianooldoni]

In checklists:
the field acceptedKey is not present if taxon isn't a synonym.

In occurrences:
the field acceptedTaxonKey is always present and equal to taxonKey if taxon is not a synonym.

Example: taxonKey = 2769766

http://api.gbif.org/v1/species/2769766
http://api.gbif.org/v1/occurrence/2006075512

Is there a reason for this asymmetry?

[mdoering]

not really. NULL values lead to the property being dropped. And pointing to oneself as the accepted I never felt is right. But yes, I guess we need to take some effort in harmonizing the API. There are more discrepancies between the occurrence and species API
