"Anillamiento de Aves - Proyecto Cruzando el Caribe" dataset of "Asociación Selva" (owner)
-> see attached excel file for data content
Similar issue to Herbier de Strasbourg: needs examination of the data served at source to find out where the duplication of ID triplets comes in. Could be:
- mapping of database tables (cartesian product), artificial duplication
- data content (multiple capture of the same object by e.g. different people)
- errors in ID values (e.g. merging multiple source datasets with same types of catalog numbers, but giving them all the same collection code)
etc
NB: the records with duplicate ID triplets nevertheless have unique GUIDs
Worth checking more closely after a quick view:
- recordedBy: duplicates vary in this field, which might indicate multiple data capture
- catalogNumber: a series of records (314) has catalog number "999999", likely some internal marker. Such records should be excluded from the public dataset
- identifiedBy varies similar to recordedBy. The scientific names and other field contents, on the other hand, look identical
Proposed next step: contact publisher and alert them to the issue, copying the node contact for information
