[ **up: [[Note-taking]]** ] --- # Joel Chan’s ‘Data Model’ In [[Chan, J. Knowledge synthesis, 2020|Knowledge synthesis: A conceptual model and practical guide]], Joel Chan outlines a data model for knowledge synthesis through note-taking/making built around the use of four kinds of notes: 1. **question notes**: posing an open question 2. **synthesis notes**: present a single, broad(ish) idea, e.g. a statement/claim (roughly = “evergreen” or “permeant” notes in other systems) 3. **observation notes**: present one *highly contextualised* observation (roughly = “literature notes” in other systems) 4. **context snippet notes**: provide the basis of facts/data in which observation notes are grounded [^1] --- [^1]: Joel Chan, ‘Knowledge Synthesis: A Conceptual Model and Practical Guide’, *Open and Sustainable Innovation Systems (OASIS) Lab* (December 2020), https://oasislab.pubpub.org/pub/54t0y9mk.
