In general yes but I do have one issue with one example (slightly off-topic I guess but important if we take these examples to somebody else):


1960/1969

This is incorrect AFAIK. This is a range and states the event started in 1960 and ended in 1969. This is different from the date occurred somewhere between 1960 and 1969. I’m not sure EDTF allows for arbitrary “event happened sometime between these dates and the length was 1 day”

Thanks
