Currently, Metadata values passed by VSR package can contain values that are either not compliance to ONAP standards or not compatible with the installed VID environment that can lead to deployment failures. This proposal proposes to add dynamic checks within SDC to be able to check passed metadata values against a registry that contains the check criteria. the content of the registry can be pre-loaded with standard static criteria, but also can be configured to add custom checks that are related to specific VID deployments.
