Case Sensitivity

Token IDs are not case-sensitive. The following requests return the same resource:
GET /instrumentidentifiers/49C26351BF7D8765E05333B9d30AA9DB
GET /instrumentidentifiers/49c26351bf7d8765e05333b9d30aa9db
Unlike the token ID in the request URL, all request fields are case-sensitive.
List matching rules:
  • Accept any case (web, WEB, WeB).
  • Store the expected case (WEB).
  • Return the expected case (WEB) metadata.
