Concepts

• Architecture

  A code and metadata repository, plus a production factory that executes workflows.

• Repository

  An organized directory of objects, each carrying machine and human metadata.

• Materialized workflow

  Every workflow node is a real folder on disk — not an abstract step in a description file.

• Impression

  Immutable, content-defined snapshots of every workflow node.

• Yuki

  The middleware (DITE) that queues operations, dispatches jobs, and owns the data.

• Runner

  REANA, local, or ssh — interchangeable backends that execute impressions.
