Great, thanks @ainashch. 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_Kumar_Xinjiang.
• [ ] Please remove all columns that are completely empty/filled only with n/a.
• [ ] The Relation_To column works with the Alternative_IDs, not the Poseidon_IDs. Is there a reason why there are two sample naming schemes existing in parallel? Why did you opt for the alternative one for the Relation_To column? I think there are multiple possible solutions to this.
• [ ] It seems you used a combination of Relation_Degree == first + Relation_Type == identical to express that two samples are from the same individual. This is not necessary. Relation_Degree can be set to identical directly.
• [ ] There is a site called G218 - just to make sure: This is a proper site name?
• [ ] The last sample has the Site set to Unknown. I think it would be better to put it to n/a.
• [ ] The Date_Type should be set to contextual for contextual ages. Date_Note then does not need the redundant *Date contextual (what does the * mean?).
• [ ] Date_BC_AD_Median can be computed as the mean of Date_BC_AD_Start and Date_BC_AD_Stop for contextual ages.
• [x] The Publication column is typically used for a bibtex key in a complete package. In this .janno-only submission we can leave it like it is for now.

Maybe you could quickly have a look :+1:
