1. Introduction

The LOCKSS system is a distributed digital preservation software system developed by the LOCKSS Program at Stanford University Libraries.

The 2.x series of the LOCKSS system stems from the LAAWS (LOCKSS Architected As Web Services) initiative, an ambitious modernization project that includes rewriting the classic LOCKSS daemon as a suite of containerized components. This version, LOCKSS 2.0-alpha3, is the third preview release on the road to LOCKSS 2.0.
