...
JSON format is a standard for Rest Api. For the conversion from JSON to Object and vice-versa will be used **org.onap.policy.common.utils.coder.StandardCoder**.
application/yaml
YAML format is a standard for Control Loop Type Definition. For the conversion from YAML to Object and vice-versa will be used **org.onap.policy.common.utils.coder.StandardYamlCoder**.
