The library data lake, from here. A companion to the medallion issue — not how the lake works, but where it’s going. Direction, not promises: what’s shipped, what’s in flight, and the horizon worth aiming at.
What’s running now (catalog, circulation, Libby, reading lists, reading levels), what’s built and waiting on a gate (a federated node of our own, encrypted customer data, authority-grade work matching), and the long aim: a catalog shared between libraries — own your data, peer to peer.
