External identifier 1 is a datatype that associates a text value to an external URL.

For example, a value annotation like [[NDL ID::00564222]] is going to be represented as:

  • in case the required
  • [[External formatter uri::$1]] is denoted on the relevant property page that specifies the NDL ID property.

Features and limitations

  • The External identifier type is a text type that requires the External formatter URI property to be denoted on the property page that uses this this type
  • The annotated uri in the External formatter URI property is expected to define a place holder $1 to mark the position of the value
  • This type can easily be combined with Has uniqueness constraint or Allows pattern to build restricted constraints as to what value inputs are expected or allowed
