  1. Provenance, Production, and Planning Bruce R. Barkstrom NOAA’s National Climatic Data Center Asheville, NC

  2. Basic Facts • Much of Earth Science (and some space science) data results from discrete production • Files • Jobs • Files and Jobs are • Denumerable • Indexable as time series • Connection between jobs files and jobs is a graph • Societal importance of climate data will require legal-strength proof of chain of custody and production

  3. Key Consequences • Jobs may use previously produced data to guide next step in production • Provenance graphs may include millions of objects • Cannot expect provenance to fit within files • Current metadata standards are (provably) incomplete • New versions of data products may be produced by 4 kinds of changes: • Input data, source code, coefficients, connectivity + hardware/infrastructure code • Time series organization of files gives a reasonable basis for a hierarchical permanent registration schema for files and file contents
