Hi Yan,

if you already have a GBIF backbone species id we keep the reference to the original taxon as it is found in checklist bank in the taxonID property: http://api.gbif.org/v1/species/6459778 • taxonID: "115241245"

From there you can then find the original WORMS id again as the taxonID: http://api.gbif.org/v1/species/115241245 • taxonID: "431166"

This is true for nearly all records in our backbone. There are just some taxa that do not have a source cause they have been added purely algorithmically. For these usages you can check the origin or accordingTo property to see why they exist, but taxonID then is lacking. Infraspecific autonyms are frequent cases of this: http://api.gbif.org/v1/species/7306268

You can also go the other way around and search CLB taxa by their source identifier: http://api.gbif.org/v1/species?datasetKey=2d59e5db-57ad-41ff-97d6-11f5fb2645...

Is it possible to use the GBIF API to convert GBIF taxon ids (e.g. 6459778, from http://www.gbif.org/species/6459778) for taxa that have originally been obtained from WoRMS, to their original WoRMS IDs (in this case 431166, see http://www.marinespecies.org/aphia.php?p=taxdetails&id=431166).
