the scientificName term was dropped because it is not part of the regular DwC relation "class":

The resource relation can relate any kind of things and GBIF needs to lookup the ids to find the scientificName of the related resource in your case. Unfortunately this is not implemented right now, so by upgrading to the latest "correct" version of the extension you will lose the related scientific name on the GBIF occurrence page.

When I look at your example the data is a little unexpected though.

The relatedResourceID is given as 701c94f1-16eb-4c1e-8449-f3b046100187:

This should be the occurrenceID of the occurrence record for the plant it feeds on (Pistacia terebinthus)

If I lookup this record in your dataset it is missing:

If I look at the taxonomic overview of your dataset it is all Arthropoda, so the related food plants all seem to be excluded?

If you only want to annotate an occurrence record with the plant it feeds on you should not be using the relations extension but instead look into dwc:associatedTaxa: http://rs.tdwg.org/dwc/terms/index.htm#associatedTaxa

Hi IPT list members,

Could anyone help me to understand what are the implications of doing an update of the Darwin Core Resource Relationship extension, that our IPT installation is asking to update?

I am particularly concerned with the dataset http://ipt.gbif.pt/ipt/resource?r=edp_tua_arthropoda_eia, that is using this extension. The table resourcerelationship.txt in the dataset uses the term scientificName to identify the name of the tree where larva of butterflies feed on. This is reflected in the occurrence data at gbif.org, for example, in this record: https://www.gbif.org/occurrence/1585354292.

I noticed that the update of the extension dropped the term scientificName. So, could anyone guide me on the changes that I need to do in the dataset, in order to be able to update the extension and have the same or equivalent information about the relationship in the record at https://www.gbif.org/occurrence/1585354292?

Best regards,

Rui
