- TOSCA language could be found here: https://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.3/os/TOSCA-Simple-Profile-YAML-v1.3-os.pdf
- A yaml file contains only one service template
- TOSCA Service Templates MUST always have, as the first line of YAML, the keyword “tosca_definitions_version” with an associated TOSCA Namespace Alias value.
- A service template could import other service templates
- namespace as URI could be an issue if used as id of a resource
- name could be extracted as host of the namespace, and version could be extracted from the postfix of the namespace.
- A pattern could be like a http://{host_namespace}/service/
- template/{x}/{y}/{z}. As example "http://tosca/service/
- template/0/0/1" we can extract name: "tosca" and version: "0.0.1"
- Version could be omitted: http://{host_namespace}/service/template. As example "http://tosca/service/template/onap/org" we can extract name: "tosca" and default version: "0.0.1"
- http://tosca/service/template/onap/org namespace/0/0/1 could be used as default namespace default
- name and version will be not present into the yaml file (service template) as now, but we can continue to use them as id of a resource
- host will be used as key to reference to external service template, and with "namespace_prefix" will be used to avoid collisions with same host but different version
- about type and type_version backward compatibility still valid
- type_version will be deprecated, type will be used as formatted string as follow:
- {type}
- {type}:{type_version}
- {host_namespace}:{type}:{type_version}
