Authoring learning content along with specifying its relationship to pedagogical scenarios is a tedious and error-prone task. This paper describes DBAT-LD (Dialogue-Based Authoring of Learning Designs), which is a chat bot (natural language dialogue system) that interacts with authors of units of learning and secures the content of the dialogue in an XML-based target format of choice. DBAT-LD can be geared towards different specifications thereby contributing to interoperability in e-learning. In the case of IMS-LD, DBAT-LD elicits and reconstructs an account of learning activities along with the pedagogical support activities [1] and delivers a Level A description of a unit of learning.
