Positioning in learning networks is a process that assists learners in finding a starting point and an efficient route through the network that will foster competence building. In the past we have explored computational approaches to positioning based on the contents of the learning network and the behaviour of those participating in it, more or less ignoring different efforts to stimulate positioning and competence development from a top-down perspective. In this paper we introduce a research agenda for positioning in learning networks, discuss several cases and give an outlook on the development of a positioning service for learning networks.
