Maps

A Map is a type which models data as key-value pairs. Conceptually, it relates closely to a Map type in Javascript or C#.

To enable this feature in Concerto, set an environment variable of ENABLE_MAP_TYPE='true' or provide enableMapType as an option to the Concerto ModelManager constructor.

Supported Key Types​

  • Primitives: String, DateTime
  • Scalars: String, DateTime

Supported Value Types​

  • Primitives: String, DateTime, Integer, Long, Double, Boolean
  • Scalars: String, Integer, Long, Double, Boolean
  • Concepts: Identified & Non-Identified
map <name> {
    o <required Concerto Key Type> 
    o <required Concerto Value Type>
}

Example:

namespace org.acme.hr@1.0.0

map Checklist {
  o String
  o Boolean
}

Types used in a Map may be imported from external namespaces in a manner similar to other imports.

namespace org.acme.hr@1.0.0 
import com.my.cool@1.0.0.Activity

map Timeline {
  o DateTime
  o Activity
}
