Data literacy is an important and rapidly developing area for information professionals and can be thought of as a specialised subset of information literacy. It spans among other things research data management, student study skills, organisational capacity, analytics and visualisation and open data consumption and publication.
I’ve made an attempt to map out some of these competencies and consider data literacy within an overall capabilities framework here on my personal blog: http://www.cems.uwe.ac.uk/~pmatthew/blog/2016/06/08/data-literacy-as-concept-and-capability
