A data interview in the library context refers to an interaction between a librarian and a researcher with a structured or semi-structured set of questions designed to elicit information about the researcher’s data practices and/or needs.
A librarian meets with a researcher to discuss their data in order to assist them with writing a data management plan or creating a data curation profile.
This is the structured interview form described in the Witt, et al publication: Carlson, Jake, "The Data Curation Profiles Toolkit: Interview Worksheet" (2010). Data Curation Profiles Toolkit. Paper 3. http://dx.doi.org/10.5703/1288284315652
This paper describes the process and results of a series of semi-structured data interviews, and includes the interview questions in the supplementary files:
