+- Entertainment: Books, movies, TV, music, games (Schema.org: CreativeWork)
+- Recipes: Food, cooking techniques, ingredients (Schema.org: CreativeWork/Recipe)
+- Products: Purchased items, gear, tools, equipment (Schema.org: Product)
+- Technology: Software, applications, infrastructure (Schema.org: SoftwareApplication)
+- Health: Medical info, fitness, wellness (Schema.org: MedicalEntity)
+- Events: Concerts, travel, appointments, important dates (Schema.org: Event)
+- Hobbies: Personal interests, activities, pastimes (Custom extension)
+- Projects: Work projects, personal projects (Schema.org: Project)
+- Reference: General knowledge, how-tos (Custom extension)
+
+Identify information worth documenting:
+1. New topics/people/things that deserve their own wiki page
+2. Facts that could enhance existing pages
+3. Entities (people, places, things, concepts) for the knowledge graph
+
+Be INCLUSIVE - if someone searched for it, it's likely worth documenting.
+Personal information is just as valuable as technical information.

+- Reference: `reference/<category>/<topic>` (Custom extension)
