populate occurrence fields based on MeasurementOrFact records

[pieterprovoost]

In several discussions (e.g. nvs-vocabs/OBISVocabs#15) the suggestion has come up that we could populate occurrence fields based on information in the MeasurementOrFact extension.

Possible target fields include:

• samplingProtocol
• sampleSizeValue
• sampleSizeUnit
• samplingEffort
• habitat
• individualCount
• organismQuantity
• organismQuantityType
• sex
• lifeStage
• reproductiveCondition
• occurrenceStatus

Populating these terms would require a mapping between the NVS and the Darwin Core terms.

I'm not aware of any existing QC flags for values amended based on extension records.

@timrobertson100 I am wondering if GBIF populate occurrence fields based on information in MeasurementOrFact extension? If there is, do you mind to please link the documentation/related issues here? Thank you so much!!

Thanks @ymgan

At GBIF we don't pull anything in today. However, we do have some code to extract sex and lifestage from dwc:dynamicProperties.

We ported the extraction of some measurements from the VertNet implementation to Java - e.g. extracting length - but this raised many questions, and we haven't moved it into our production processes. You'll find other parsers we ported but don't yet use here.

Edited to add: we're interested to see where you may take this, and looking to learn from you. Our plans aren't really clear.
