- Here are my 9 proposed top-level topic categories
- Water
- Food
- Public health
- Culture and community
- Communication and information technology (maybe just "Information technology" or "Communication and information")
- Energy (notice not Power and Energy as energy implies both)
- Land, materials and construction
- Transportation (most debatable, could fit some under energy, some under culture and then just have a Transportation portal)
- Metaconcepts (these will mostly be concepts that are implicitly incorporated in many different pages. They will be mostly definitions, that are linked to inline from the text of other pages)
- These 9 top-level categories are based on 8 basic human needs
- Water
- Food
- Health
- Community
- Knowledge
- Energy
- Shelter
- Transportation (arguable)
