8.4. TOSCA model
8.4.1. Table D1. ONAP Resource DM TOSCA/YAML constructs
Standard TOSCA/YAML definitions agreed by VNF SDK Modeling team to be used by VNF vendors to create a standard VNF descriptor.
All definitions are summarized in the table below based on the agreed ONAP Resource DM TOSCA/YAML constructs for Beijing. Their syntax is specified in ETSI GS NFV-SOL001 stable draft for VNF-D.
