Question
What is knowledge graph portability?
Quick Answer
Filing systems come and go but a well-linked graph retains its value regardless of how you browse it.
Example: Niklas Luhmann's Zettelkasten — 90,000 paper slips linked by a numbering system he invented in the early 1950s — survived his death in 1998, was purchased by the University of Bielefeld, digitized, and published online in 2019. The slips were written in a format any literate person can read: handwritten German on index cards. The linking system — branching alphanumeric IDs like 21/3a1p5c4fB — required no software, no database, no proprietary viewer. Sixty-seven years after the first card was filed, the entire graph was migrated to a digital medium without losing a single connection. The tool changed. The graph persisted.

After completing this path you will have a capture habit that catches thinking before it decays, notes structured so both you and an AI can retrieve them (atomic, identified, context-rich), a personal knowledge graph AI tools can answer from, and the review loop that keeps the system alive. Ask-don't-search becomes your default.
