Lore is a software system for version control.
Epic Games originally developed Unreal Revision Control for internal usage. They have released it as Lore to be an open-source version control system designed entirely around the large file needs of video game and multimedia projects. Lore is designed to be fast and efficient for large files including binary files, and be easy-to-use including for 3D artists and more. It has access control features to ensure different teams can protect access to their assets.[2][3]
Design
Lore uses content addressed storage based on hashes to achieve automatic deduplication, integrity validation, and efficient caching. Revisions use Merkle trees to create a history. On-demand hydration allows developers to download a fraction of a repository as needed. Partitions provide access control to individual teams with separate NDAs. Lore uses a centralized server (like Perforce), but adds intelligent caching to scale throughput. This gives teams a single source of truth while avoiding the bottleneck of every request hitting the origin server.
Lore is most similar to Perforce in prior art. It has file-level locking for unmergeable content, but unlike Perforce it has partitions for sub-repositories instead of per-path ACL.[4]
