I was wondering how I could frame/explain in my CV that I built the datasets used in several publications outside of my field. I'm in the health sciences but have worked for a couple social science professors for several years. In this work I built several of their datasets that were used in papers. However, due to my lack of knowledge of their field and lack of contribution to the papers (beyond the dataset) I am - quite reasonably - not included as an author.
How can I best frame this work on my CV and for PhD applications?
Thanks!
Edit: spelling
