+## Kotlin TD DSL
+
+If you don't like annotations and prefer to build Thing Descriptions in code, you can also make use of a type-safe Kotlin DSL to define Thing Descriptions.

+```
+ wot.produce {
+        id = "agent"
+        title = "Agent"
+        objectType = Type("Agent")
+        intProperty("propertyName1") {
