Thanks, @bamorim-bio, great. We'll take a look.

Thanks for preparing this .janno file! I see the following issues

• The package name does not follow our expected standard of Year_AuthorName_RelevantKeyword. I propose 2022_Liu_Micronesia.
• Please remove all columns that are completely empty/filled only with n/a.
• In the lists for Relation_Degree there can not be any n/a values. Documenting a relationship of "unknown" degree would be a pit pointless, right?
• What do the many other values in Relation_Degree mean? They are not specified in Relation_Type either and are thus not informative. Is there no way to specify them further? At least there should be a an entry in Relation_Note to explain them.
• The column Endogenous contains a lot of mixed entries, where numbers are expected.
• Date_C14_Labnr should also include the Laboratory identifier PSUAMS-, not just the number of the age.
• Date_Note should only document additional details of the dating, not the actual dating. Contextual dates like [1000-1668 CE] should be entered in the columns Date_BC_AD_Start, Date_BC_AD_Median and Date_BC_AD_Stop.

Maybe you could quickly have a look 👍. Please run trident validate --janno on the file after you implemented the necessary changes.

I will review this Janno once more, and we would like to add the genotype data from AADR here (it's David's labe that made the data, so that should be fine).
