​​Goals

​​Per Approved Working Group Proposal below - (subject to clarification and change)
  • ​​Test and and validate CLFs
  • ​​Determine how implementation-related information be communicated to enable implementers
  • ​​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)

  • ​​Reference Image(s) - before/after
  • ​​Implementation Guide
  • ​​An example implementation - refer to ociochecklut​ (e.g. it is a good example of parsing CLFs and issuing useful error messages to user when CLF is invalid)
  • ​​A tool for those who don’t have a way to compare before/after images - OIIO idiff​ modified for use with testing tolerances
  • ​​Plug-fest(s)?
