Google Wave Whitepapers

Google Wave (sadly deprecated) has pioneered a lot of what drives modern-day Google Docs, Slides, etc. in terms of an OT framework – thankfully, the project has led to a series of whitepapers discussing the technologies present in Wave, and even more happily, the original source code was open-sourced.
