# AI Wiki - PKM - Zone-Based Organization Zone-based organization structures a knowledge base by function (what type of thing a note is) rather than topic (what the note is about). Instead of folders like "Programming," "Health," or "Business," zones are defined by the role notes play in the system: Meta, Actions, Areas, Journal, Resources, Archives. This is an extension of the PARA method that adds Meta and Journal zones. ## The Zones **Meta.** System configuration, identity, AI assistant infrastructure, templates, documentation about the system itself. The zone that makes the vault self-describing. **Actions.** Goals, plans, projects, tasks. Everything with a deadline, a status, or a next step. This zone is where work gets done. See [[AI Wiki - PKM - GTD and PKM]] for the action management philosophy. **Areas.** Ongoing domains of responsibility and interest with no end date. Literature notes, permanent notes, maps of content, creations. The heart of the knowledge base. **Journal.** Time-based capture: daily notes, weekly reviews, monthly reflections, yearly reviews. The chronological backbone. See [[AI Wiki - PKM - Daily Notes]] and [[AI Wiki - PKM - Periodic Reviews]]. **Resources.** Reference material: templates, checklists, lookup tables, external documentation. Things you consult but do not develop. **Archives.** Inactive items: completed projects, retired goals, obsolete references. Kept for historical value but removed from active navigation. ## Why Function-First Beats Topic-First Topic-based organization seems intuitive but scales poorly. The problem: topics proliferate. A note about "using spaced repetition to learn programming" could go in "Learning," "Programming," "Productivity," or "Spaced Repetition." Every new note triggers a classification decision, and the decision gets harder as folders multiply. This is the core issue that [[AI Wiki - PKM - Tagging and Metadata]] solves for retrieval, but the folder problem remains for storage. Function-based zones eliminate the classification problem for folders. A project note goes in Actions. A permanent note goes in Areas. A daily note goes in Journal. The function of a note is almost always unambiguous, even when its topic is not. Functions are stable (you will always have projects, areas, and journals) while topics shift with your interests. ## Extension of PARA The [[AI Wiki - PKM - PARA Method]] defines four categories: Projects, Areas, Resources, Archives, organized by actionability. Zone-based organization extends PARA by adding Meta (the self-describing layer) and Journal (the temporal layer). These additions are critical for mature systems: Meta enables AI readiness (see [[AI Wiki - PKM - Context-as-Code]]), and Journal provides the chronological capture that PARA assumes but does not specify. ## Zones and Note Types Within each zone, [[AI Wiki - PKM - Typed Notes]] provide further structure. The Areas zone contains permanent notes, literature notes, maps of content, and creations, each with its own template and properties. Zones define where notes live; types define what notes are. Together they form a two-dimensional organizational schema: function (zone) x structure (type). ## Key Points - Zones organize by function (what a note does) not topic (what it is about) - Six zones: Meta, Actions, Areas, Journal, Resources, Archives - Function-first organization scales because functions are stable; topics proliferate - Extends PARA by adding Meta (system self-description) and Journal (temporal capture) - Zones define location; note types define structure; together they form a complete schema ## Open Questions - Is the six-zone model universal, or do some workflows need additional zones? - How should cross-zone linking work (e.g., a daily note referencing a project)? - At what vault size do zones provide measurable navigation benefits over flat or topic-based structures? ## References - Vault: Obsidian Starter Kit - System - Zone System, Obsidian Starter Kit - Theory - Tiago Forte, "Building a Second Brain" (2022) — PARA method - Johnny Decimal system — numerical zone-like structure ## Related - [[AI Wiki - PKM - PARA Method]] - [[AI Wiki - PKM - Typed Notes]] - [[AI Wiki - PKM - Tagging and Metadata]] - [[AI Wiki - PKM - Information Architecture for PKM]] - [[AI Wiki - PKM - Daily Notes]] - [[AI Wiki - PKM - Context-as-Code]] - [[AI Wiki - PKM - Life Operating Systems]]
