The manifest file tells the receiving system what files are included with this set of data. The ClassLink OneRoster Server only processes bulk imports and requires that entire sets of data be provided. This means that an import MUST include all the rostering files and optionally the demographics file, and if it is to include any of the files highlighted in blue, all 3 of those must be provided. Categories, lineItems and results should be marked absent.
The manifest file is a 2 column file and for most new clients. The manifest file is available here.
