Concepts

The core concepts the rest of the book builds on:

• Roots: Storage locations that Canon tracks
• Sources: Files discovered on disk
• Objects: Unique content identified by hash
• Sources vs. Objects: How files relate to content
• Facts: Metadata attached to sources or objects
• Exclusion: Dismissing content from consideration, reversibly
• Resolution: The goal of the work, and the standings on the way there
• Decision Provenance: How Canon records what you did, to what, and why
• Retirement, the Book, and the Shelf: How a resolved root leaves the index
