Hey, I’ve been mapping out the base grid and I’m looking for a reliable file format to store the blueprint. I know you’re all about preserving old formats, so what would you say is the most durable and accurate format for a long‑term architectural archive?

I’ll hand you the one that survived the digital apocalypse – a DXF. It’s plain text, so it can be read by a toaster, and the version history is baked into every file. If you need a binary that the machines love, DWG from the old‑school CAD era is the next best. For a true archival stamp, wrap that in a PDF‑A and you’ve got a sacred bundle that even the cloud won’t forget. Remember to embed a checksum in a comment header, or the file will wander into oblivion.

If you’re aiming for longevity and the highest fidelity, lock it in PDF‑A first—those archives are designed to survive for centuries. But PDF alone only holds raster images and flat geometry. Wrap the geometry in a format that preserves the underlying data, like IFC for building models. That way you keep every dimension, material, and relationship intact. Add a checksum or hash in the header, and store the PDF‑A + IFC bundle in a redundant, temperature‑controlled archive with a version‑controlled naming convention. That’s the most reliable stack for a long‑term architectural archive.

I agree, PDF‑A is the holy grail for longevity, but don’t forget the magic of a solid IFC layer on top—those are the living bones of a building. Keep the IFC as a separate, compressed .zip, and inside add a tiny XML snippet that lists every version hash. Then stash the whole bundle in a vault that is temperature‑controlled and read‑only. And if you’re feeling extra cautious, put a handwritten ledger next to it that says “Created 2026, reviewed 2027.” That’s how you keep the soul of the blueprint alive for centuries.

Nice, you’re on the right track—IFC inside a zip keeps the data lean, and the XML hash list gives instant integrity checks. Just make sure the zip uses a fixed CRC algorithm, and keep the ledger on a separate media, maybe an RFID‑tagged hard drive. That way if the PDF‑A file gets corrupted, the backup is still intact. Keep the vault in a 20°C climate zone and run quarterly checksum audits. You’ll have the blueprint alive for the next century.
