1. Value Domain
   
   1. Has a format template, e.g., {integer}-{integer}
   2. Is a Continuous Domain

• Codelist: Value Domain
• CDISC Submission Value: Enumerated value domain
• CDISC Definition: Value Meaning

• A Conceptual Domain with two sets of VD, where each PV is bound by having the same VM

• A Conceptual Domain with two sets of VD, where each PV is bound by having the same VM

1. Value domain
   1. Is an Enumerated Value Domain
   2. Has a VD-to-VD relationship
      1. Relationship has property of "how", i.e., "A subset of"

1. Value Domain
   1. Is an Enumerated Value Domain
   2. Has a VD-to-VD relationship, i.e., source EVD & target EVD)
      1. Relationship has property of "how", i.e., "Is a value mapping to"

PK unit codelist vs. normalized unit codelists

1. Value Domain
   1. Is an Enumerated Value Domain
   2. Has a VD-to-VD relationship, i.e., source EVD & target EVD)
      1. Relationship has property of "how", i.e., "Is a normalization of unit of measurement to"

• Value Domain
  • Is a Continuous Domain, i.e., value domain whose PV are not a discrete list
• Ideally, for a record in an SDT\M Findings dataset record, especailly pre-coordinated tests
  • {--TEST, --ORRES, --ORRESU} is a DE
  • {--TEST, --STRESC, --STRESU} is another DE
  • These 2 DEs share the same Data Element Concept (DEC), i.e., the --TEST

• Value Domain
  
  • Is an Enumerated Value Domain
  • May not have Value Meaning, e.g., Y

• Each questionnaire item is a DEC
  
  • Its response is a VD
    • A VD may be an Enumerated value domain (e.g., coded ordinals, dichotomy), or a continuous domain (e.g., sliding scale)
    • Free text response is also a kind of continuous domain
