Plain Text, Backlinks, and Metadata
Markdown plus backlinks offers a durable foundation. Use readable filenames, human-friendly IDs, and frontmatter or inline attributes for light structure. Keep metadata minimal but meaningful: status, source, claim type, and review cadence. These small choices enable powerful queries, predictable maps, and consistent graph behavior across tools. Most importantly, they make your notes survivable outside any single application, preserving navigability, authorship context, and link integrity when you inevitably reorganize, migrate, collaborate, or temporarily work entirely offline.
