In DwC I would use Occurrence core rather than Event core in order to be able to attach DNA sequences to the identifications through either the GGBN amplification extension or the DNA derived data extension (once it is available) This will of course this will duplicate Event fields across Occurrence rows, but otherwise you can´t link the DNA sequences.
In the Occurrence core file I would have the following terms:
So if I were to use the same eventID for alle "occurrences" that belong together GBIF would recognize this as an event sampling? If so, why do we need an event core than? Still this would mean I have to double primary occurrence data one million times if I have one million taxa in a sample.
Yes, that would be recognized as an event. Example
The reason we need Event core is that we loose the information of parent events when flattening event data to Occurrences. In a future richer model than the Star schema, we want to be able to model hierarchical events.
But for now you can only choose one Core, i.e. do you want rich occurrences with DNA sequences or do you want to avoid data duplication and use Event core.
Ok thanks. If I click on "77 occurrences" it takes me to occurrences, but the parameter "event_id" disappears from url and all 30.091 occurrences are shown. Is this not yet implemented?
That was a bug in the portal - fixed now.
I did a test mapping using the event core for one environmental sample record with 10 example identifications from GGBN's partner CALeDNA.
