Based on my playing around with these ideas, I think you need the following tools in a DRY word-processor:
- Real-time recognition and suggestion of source statements for factual claims or references (this means the word processor must be linked to an archive or database of some type).
- Successive text-entry fields for additional explanations, each of which threads back to the original post with correct URLs embedded as hyperlinks.
- A means of submitting and improving new definitive statements.
- A way of notifying the writer of articles that may need to be reconsidered in light of changes to foundational factual statements.
- Machine automation of contextual markup for RDF, etc.
For the reader to get the full benefit of this approach to writing, you would need a Web page that would:
- Open summary statements in-line.
- Display documents as resource outlines
- Display the context of documents as derived from their RDF structure.
- Allow readers to spot divergent points of factual dispute.
