  • Determine the minimal set of capabilities that should be required of implementers
  • Determine if different levels/profiles of CLF support be defined
  • Determine if it would be helpful to have a "reference implementation”
  • Determine if any recommendations should be provided for how to bake CLFs into approximate representations
  • Develop recommendations for how to set and/or propagate the metadata fields
  • Determine what tests are recommended for the first plug-fest

Anticipated Deliverable(s)

  • Tests and test files, documentation, plug-fest results, code…
