SUMMARY:Core Flow: sovereign nature data\, readable in 2075 - Joris Rölin

DESCRIPTION:Core Flow is the data platform behind Dutch nature monitoring\
 , designed around one question: what will someone be able to read in fifty
  years\, with no account\, no licence\, and no us? Everything is stored as
  open files (Parquet) on S3-compatible object storage and queried directly
  with DuckDB\, so there is no database to outlive and no proprietary layer
  to replace. Each dataset carries a stable UUID identity\, so names and pa
 ths can change without breaking references\, and data is append-only and h
 istorized\, so you can ask what was known on any past date. There are no s
 tanding servers: scheduled jobs run on the GitLab CI runners we already ha
 ve. The talk walks through the principles (no vendor lock-in\, sovereignty
 \, durability and cost) and how each one shaped the architecture.
