Item-based feeds with syllabus content can be created and run to populate syllabus content in Concourse. Clients typically do this on an infrequent (e.g. once a year) basis to migrate from an existing syllabus or related solution, to populate a large number of course-level templates with artifacts like course descriptions, or to mass set item permissions.
The required format for these custom syllabus content feeds will be very similar to that of a course feed. For example if a feed for the Description item is to be processed, this pipe-separated file should contain columns for: A course identifier, the description itself, additional notes, and finally comments.
