Questions posed by NIST:

Some specific questions we are interested in answering both in the short and long term include:

  • Does this bring value to federated scenarios and identity solutions?
  • Would your community or organization profile this schema to support a specific solution or sector?
  • Is the body of attribute and attribute value metadata complete? What is missing? What should be removed?
  • Is the categorization adequate and complete? Did we miss anything that is critical to improve trust and confidence in decision making based on federated attributes?
  • Is trust-time vs. run-time sufficiently considered? Should the defined attribute metadata be shifted among these two lifecycle phases?
  • Is the delineation between attribute and attribute value metadata clear and are both required in this schema?
  • Is level of effort required to integrate and leverage the schema commensurate with the value of the schema?
  • Does the addition of the metadata negatively impact performance of systems?
