Organizing Knowledge
Published April 05, 2025
1. Hierarchical Structure (Tree Format)
- Best for: Categorized knowledge, textbooks, formal systems.
- Example:
Science
├── Physics
│ ├── Mechanics
│ └── Thermodynamics
└── Biology
├── Cell Biology
└── Genetics
- Tools: Folders, Notion databases, mind maps.
2. Network/Graph Structure (Zettelkasten Style)
- Best for: Ideas, concepts, and connections between them.
- Key Feature: Notes link to other notes; everything is connected.
- Tools: Obsidian, Roam Research, Logseq.
3. Matrix/Grid Structure
- Best for: Comparing things across dimensions.
- Example:
| Theory |
Advantages |
Weaknesses |
Use Cases |
| A |
Fast |
Inaccurate |
X |
| B |
Precise |
Slow |
Y |
- Tools: Spreadsheets (Excel, Notion, Airtable)
4. Chronological (Timeline) Structure
- Best for: Histories, case studies, project logs.
- Example:
2022 - Started learning Python
2023 - Built first project
2024 - Created personal website
- Tools: Timelines in Notion, Trello, journals
5. Problem → Solution → Insights Structure
- Best for: Technical learning, case studies, project-based notes.
- Template:
- Problem
- Attempts
- Solution
- Insights / Lessons learned
6. PARA Method (by Tiago Forte)
- Best for: Knowledge related to productivity or projects.
- Breaks down into:
- Projects – active tasks
- Areas – ongoing responsibilities
- Resources – reference material
- Archives – inactive items
