relation

attribute

id
  • string
  • no default required
  • should be unique within relationships as it is the key which you search against etc

elements

displayName
  • string
  • default
  • name of the relationship, can be used to return to the UI
predicate
  • string
  • default
  • name of the relationship in the service layer
subject
  • string
  • default
  • expects n or 1 to help define hierarchical relationships
object
  • string
  • default
  • expects n or 1 to help define hierarchical relationships
inverseOf
  • string
  • default
  • if this is a hierarchical relationship which is modeled in the service layer as a single directional relationship then this is how you specify that it is the inverse of the relationship specified by the id here
showsiblings
  • string
  • default
  • if set and this is a hierarchical relationship then the UI requires a list of the sibling relationships. The value of this tag is {repeatId}:{fieldId} that the data whats to be shown in - relates to the uispec
childname
  • string
  • default
  • for 1:n hierarchical relationships where multiple results will be returned for this context. Childname specifies the name of the field id in the uispec
directional
  • boolean true|false 1|0 yes|no
  • default true
  • sets up the relationship as a two-way(false) or a hierachical one-way(true)
sourceTypes
  • set of strings (currently uses service urls of the records)
  • default {""}
  • allows restriction of the types of record that can be used with this relationship. If 'all' is specified then there are no restrictions
    • sourceTypes should the service names of the recordTypes e.g. if service-url is defined use that else use id
    • when directional = false sourceTypes should equal destinationTypes
destinationTypes
  • set of strings
  • default {""}
  • allows restriction of the types of record that can be used with this relationship. If 'all' is specified then there are no restrictions
    • sourceTypes should the service names of the recordTypes e.g. if service-url is defined use that else use id
