Thanks Yani!! I won’t be able to attend the meeting today due to schedule conflict, but please see my comment below:


A statement about whether user reported every species observed
- Thanks Wesley for the definition, I appreciate it!
- My only remarks is it is possible that the non-target taxa observed is reported but could not be identified it to species level. So I am not sure how to document this seeing its use is intended for species-level observations?

Should targetSizeScope be included?
I am not sure. In my humboldt opinion, it is probably a good idea to have data provider document the sampling effort such as mesh size of the net for the trawl. The information about target size scope can perhaps can be inferred?

We have some discussions about the need in OBIS: https://github.com/iobis/quality-taskteam/issues/35
There is a similar term in cam trap-dp: https://github.com/tdwg/camtrap-dp/issues/217, https://tdwg.github.io/camtrap-dp/data/#observations.classificationconfidence
My concern is will this vary across different taxa? If so, how to document this at Event level? (since Humboldt is an extension to the Event?) Maybe it’s a term to be proposed for Identification class?

Looking at the terms again, I have some concern about the amount of boolean terms that is dependent on other table such as the Event core table and Occurrence extension table. For example, hasMaterialSample, isAbundanceReported, isAbsenceReported. On average, I work with 3 tables (excluding Humboldt). I think it is a little error prone to have the fields dependent on other table IF it is something that can be derived. The reason is, data provider often change things in different tables and that including the IDs (eventID, occurrenceID). It is very common that information on one table is updated but not the other. In my experience, many data providers are still using spreadsheet, so I am a little worried that these fields may lead to inconsistencies or people will not use it because it is a lot of work.

isAbundanceReported - if there is a value in individualCount or organismQuantity, organismQuantityType of the occurrence records of the Event, would that perhaps sufficient to imply that the abundance is reported? (Please correct me if I am wrong)
isAbsenceReported - same as above, but looking at occurrenceStatus column.
hasMaterialSample - same as above, but looking at the MaterialSampleID column. If materialSampleTypes (Humboldt term) has a value, then perhaps that is sufficient to imply that hasMaterialSample is true?

I hope I am making sense~ Thank you all very much for the hard work!


PS: I got a date for Valentine’s! It’s February 14 (haha) :)

Hi valentines!

I hope everybody is great.

Let meet tomorrow and discuss the following items:

  *   review taxonomic scope related terms (see slide 13 and 14 here<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.google.com%2Fpresentation%2Fd%2F18n83tttDvWDLI5UM30LIsfqrbpH5nbyrwIKjuUY_glE%2Fedit%23slide%3Did.g2037ee016fb_3_0&data=05%7C01%7Cymgan%40naturalsciences.be%7C34c7e438d7164fd1ab5a08db0ec598ca%7C4da8d35db472419c9e15665786aadbfb%7C1%7C0%7C638120014056577433%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=Hg9FFiQkALT6A8gnqgVPDCdg2KfQbcpTjcqn9X7cJjE%3D&reserved=0>)
