DCTAP Elements

In the DCTAP Model, a Shape groups a set of Statement Templates, each of which describes one type of Statement in Instance Data about a specified Entity. Each of these two components (Shapes and Statement Templates) has its own (extensible) set of DCTAP Elements:

Statement Template elements

• propertyID / propertyLabel
• mandatory / repeatable
• valueNodeType
• valueDataType
• valueConstraint / valueConstraintType
  • Value constraints with no value constraint types
  • Value constraint types with no value constraints
  • Built-in value constraint types
    • Picklist
    • Pattern
    • IRIStem
    • LanguageTag
    • MinInclusive / MaxInclusive
    • MinLength / MaxLength
  • Custom value constraint types
• valueShape
• note

Shape elements

There are two Shape elements. If the shapeID element is not used in a given DCTAP instance, it will be assigned a default value (which can be customized in the config file - see Default Shape Identifier).

• shapeID / shapeLabel
