We've been doing some validation across the dataset as a whole, and one thing that has jumped out is that the various free-form text fields are truncated to 255 (or sometimes 256) characters at the schema level. Some of the work that our researchers have done on the edX dataset in the past has involved analyzing forum posts (running tone analysis, for example, and correlating that to outcomes or retention). Obviously that requires the full text of a post, message etc. Would it be possible to add the full body of any free text fields to the dataset, rather than just the first 255 characters?
