Discussion Points

• LexEVS model and implementation are more complex than requirements of most NCI value sets
• NCI Thesaurus may have enough assertions to adequately describe value sets without external modeling
• User needs beyond the browser should be recorded
  • should include report writer
  • excel spread sheet file consumers
  • any users of value set definition and resolved value set XML files.
  • consumers of the value set api
  • Neoplasm value set types (containing self asserted hierarchy)

Proposed Support and Solutions

• Provide concurrent value set loading capability.
• Provide OWL export of value sets
• Provide programmatic Access to value set definition expressed as XML
• Provide examples for regular api level access of value set members
• Provide support for NeoPlasm like value sets.
