Hi Yani,

For the summaries, I would simplify the explanation to something like this:

- *ebird case: *The target was to count all detectable individual birds. Because sumQuantities = TRUE, the total number of birds detected during an event is the *sum** of *organismQuantities for that event (2+13=15; every row for every target for the event counts toward the total for the event). Furthermore, the total number of birds of a given species detected during an event is the sum *of *organismQuantity for that species for that event (2+13=15 *H. rustica*; every row pertaining to the species counts toward the total for that species for that event). IF there had been an additional target row with observedTaxon = "Aves" and organismQuantity = 15, the total number of birds detected would have been 30 (2+13 *H. rustica* and 15 unidentified *Aves*. - obis case: The target was to count all detectable *E. antarctica* as well as the subsets of *E. antarctica* in the life stages larva and postmeta. Because sumQuantities = FALSE, the total number of *E. antarctica* detected during an event is the count in the row (15) corresponding to the least specific category of *E. antarctica* (that with no lifeStage specification). Because the count in the least specific category is equal to the sum of the rows with lifeStage, there were no other *E. antarctica* detected. *IF the E. antarctica count without any lifeStage distinction (bw_target_3) had been 17 instead of 15, that means that there were 17 total E. antarctica detected in the event and 2 of them were not larvae or postmetas.*

Cheers,

John

Hi all,

In preparation for our meeting this week. I will kindly ask you to *review the definition of the new term sumQuantities* which allows the users to undertand if the dwc:*organismQuantity should be summed or not to get final species counts (see below).*

Also, we started the Implementation Experience Report https://docs.google.com/document/d/1RFdSHoyzWCQk9qO6uup4xQjWOMzPyBb-A0mcjj98hbk/edit# *,* based on the Audubon example shared by Steve. *Please start completing the sections with your experience or thoughts*.

*Thank you and see you on Wednesday!*

sumQuantities Please suggest changes for current definition/comments below!

1. *Definition: The total detected quantity for a Taxon in an Event is

the sum of all dwc:organismQuantity for the Taxon in the Event.* 2. *Comments: Recommended values are True and False. If True, the total detected quantity of organisms for a Taxon in an Event is the sum of all dwc:organismQuantity for the Taxon in the Event and dwc:organismQuantity can be added to get the total detected quantity of organisms in an Event. If false, the total detected quantity of organisms for a Taxon in an Event is the dwc:organismQuantity of the least specific category listed for the Taxon in the Event and dwc:organismQuantity can not be added to get the total detected quantity of organisms in an Event. * 3. *Examples: "`true`, `false`"*

*For more context, see Humbold case study https://docs.google.com/document/d/1eGD69E-KzqdOcjh637iPrp1gv_J55CM2VPAjD1PSu_w/edit#. Based on the example tables that John created I simplified below for easy interpretation of this term (PLEASE JOHN CORRECT IF ANYTHING IS WRONG):*

• *ebird case where organismQuantity (for ebird_target_1 = species

level) is the sum of organismQuantity for that specific taxonomic level (only 2 organisms at the species level were detected not including the subspecies). Then, **sumQuantities =TRUE because t**o get the total number of organisms detected in the Event **without a taxon level distinction (**15), the organismQuantity CAN be added (2+13=15). IF there had been a target "Aves" with count 15 (ebird_target_0), the total number of organisms detected would have been 30 (15 Aves unidentified to species and 2+13 Aves identified to species.*

• obis case where *organismQuantity (for bw_target_3 = Electrona

antarctica without lifestage distinction) *is already the sum of organismQuantity for the more specific targets (lava and postmeta, 15=13 +2). Then, *sumQuantities = FALSE because t**o get the total number of organisms detected in the Event without a lifestage distinction (15), the organismQuantity CANNOT be added (15+2+13=30). IF the Electrona antarctica count without any lifeStage distinction (bw_target_3) had been 17, that means that there were 17 total E. antarctica and 2 of them were not larvae or postmetas.*
