I recently published a paper, which includes a link to a data repository in which that data is available. Now, with other researchers, we are combining our datasets in a meta-analysis.
I was wondering what the etiquette was regarding inclusion of the co-authors of the first paper (who are not involved in the meta-analysis, but were integral to collecting my initial dataset).
I think I should send them a courtesy email saying "I'm doing meta-analysis with these other people using our dataset that can be downloaded by anyone".
Should I do more (beyond this, and an acknowledgement in the paper)?
