Hi @sformel-usgs,
As you have pointed out, there are two ways to handle this within the Darwin Core format:
If I understand correctly there's 2-3 stable isotope measurements per body part which is only ~9 P01 terms if we went with option 1. Option 2 could result in a more complicated event table. Could you let me know which option you would prefer?
Many thanks, Roseanna
@roswri thank you for the thoughtful response, and my apologies for the delayed answer. I would prefer the second option, with the new P01 term for body part. I think this aligns with the response from #28.
@sformel-usgs Option 2 is indeed attractive and it saves us from creating many combinations for various body parts however we discussed this ticket at the OBIS vocab group meeting today and we were wondering how would the appropriate body part be linked to their respective stable isotope measurement value if they sit under the same occurrence ID? I understand that it is not currently possible to do this. Could you explain how you would see this working?
I found the parentMeasurementID thread we were wondering about yesterday (https://github.com/tdwg/dwc/issues/362) and based on that, I wonder if such data could be formatted like:
Occurrence table eventID | occurrenceID | occurrenceStatus | basisOfRecord | scientificName |
---|---|---|---|---|
e-1 | occ1 | present | materialSample | Salmo salar |
e-1 | occ2 | present | materialSample | Salmo salar |
eMoF Table
eventID | occurrenceID | parentMeasurementID | measurementID | measurementType | measurementValue |
---|---|---|---|---|---|
e-1 | occ1 | occ1_gill | body part | gill | |
e-1 | occ1 | occ1_gill | spp1_gill_isotope | Concentration of isotope | 10 |
e-1 | occ1 | occ1_muscle | body part | muscle | |
e-1 | occ1 | occ1_muscle | occ1_muscle_isotope | Concentration of isotope | 20 |
e-1 | occ2 | occ2_gill | body part | gill | |
e-1 | occ2 | occ2_gill | occ2_gill_isotope | Concentration of isotope | 10 |
e-1 | occ2 | occ2_muscle | body part | muscle | |
e-1 | occ2 | occ2_muscle | occ2_muscle_isotope | Concentration of isotope | 20 |
But I am not sure if parentMeasurementID is implemented in the IPT, or if there is an issue in having multiple measurementType: body part linked to the same occurenceID..
Problem:
We need to describe stable isotope measurements from various body parts of the same sampled organism. There are 2-3 measurements per body part (e.g. gill, muscle, shell) per organism. The S12 terms could completely meet our needs for
MeasurementValue
but I couldn't find a good way to indicate a MeasurmentType ofbodyPart
. I don't think it's useful to incorporate it into many terms as a subcomponent because (1) it would be useful to be able to group this data by body part value and (2) it will result in taxon x body part # of terms, which feels excessive.Request
Create a new P01 term,
bodyPart
. This term would be used in eMOFMeasurementType
and allow the specification of terms from S12 asMeasurementValue
.Suggested Definition
any part of an organism, such as an organ or extremity defined in vocabulary S12.
