Can anyone suggest a reference that deals with a decent, contemporary taxonomy of data sources? There is the old taxonomy by Cattell: Q-Data (= Questionnaire Data), T-Data (= Test-Data), and L-Data (= Life-Data), which is sometimes extended with O (for observational data). But nowadays, this seems a little bit old-fashioned and meager.

There is a good paper by Kroehne & Goldhammer (2018) discussing para-data, meta-data, and auxiliary-data. But what about blood marker, MRI data, and so on? Anything else you could suggest?
