# PKM Strategy: Markdown vs HTML Second Brain Architecture

Category: Memory & Storage
Stack: Obsidian, HTML Dashboards, JSON-LD, Markdown

## Overview
The trade-offs between pure markdown notes for future-proof portability and interactive HTML for dynamic enterprise dashboards.

## The Problem
Markdown is static and cannot render interactive calculators or dynamic KPI filters; pure HTML is verbose and hard for agents to parse.

## Production Rule
Adopt a hybrid architecture: plain Markdown for knowledge capture and reference specs; interactive HTML/JS for executive client dashboards.

## Code / Specification
File: `hybrid_pkm_spec.md`

```data architecture
Markdown Layer:
- Journaling, architectural field notes, reference specs
- Consumed by LLMs and terminal agents without layout noise

HTML/JS Layer:
- Interactive financial models, covenant calculators, executive KPI views
- Consumed by human stakeholders for decision-making
