Keyname
Required
Type
Description
mime_type no
string
The required mime type property for the Artifact Type.
file_ext
string[]
The required file extension property for the Artifact Type.
properties
list of
property definitions

3.6.7 Artifact definition
Keyname
Required
Type
Description
type
yes
string
The required artifact type for the artifact definition.
file
The required URI string (relative or absolute) which can be used to locate the artifact’s file.
repository no
The optional name of the repository definition which contains the location of the external repository that contains the artifact. The artifact is expected to be referenceable by its file URI within the repository.
description
The optional description for the artifact definition.
deploy_path
The file path the associated file would be deployed into within the target node’s container.
No properties as defined currently in tosca-simple-profile-yaml v1.1 and v1.2. May need to added. The properties can only be considered as metadata information of the artifact itself.

3. SwImageDesc Metadata of the image(could be mapped as artifact name)
Attribute
Qualifier
Cardinality
Content
Description id M 1
Identifier
The identifier of this software image.
name
String
The name of this software image.
version
The version of this software image.
checksum
The checksum of the software image file.
containerFormat
The container format describes the container file format in which software image is provided.
diskFormat
The disk format of a software image is the format of the underlying disk image.
minDisk
Number
The minimal disk size requirement for this software image. The value of the "size of storage" attribute of the VirtualStorageDesc referencing this SwImageDesc shall not be smaller than the value of minDisk.
minRam
0..1
The minimal RAM requirement for this software image. The value of the "size" attribute of VirtualMemoryData of the Vdu referencing this SwImageDesc shall not be smaller than the value of minRam.
Size
The size of this software image.
swImage
Identifier (Reference to SwImage)
This is a reference to the actual software image. The reference can be relative to the root of the VNF Package or can be a URL.
operatingSystem
Identifies the operating system used in the software image. This attribute may also identify if a 32 bit or 64 bit software image is used.
supportedVirtualisationEnvironment
0..N
Identifies the virtualisation environments (e.g. hypervisor) compatible with this software image.
Metadata of the image, it is not required for TOSCA orchestrator (could be a property of the artifact)
Could move into vnf package manifest file
Type of the artifact or file_ext of the artifact type(such as, tosca.artifacts.Deployment.Image.Container.Docker, tosca.artifacts.Deployment.Image.VM.ISO)
Could delete and use the value “size of the storage” in VirtualStorageDesc
Could delete and use the value in VirtualMemoryData
Metadata of the image, it is not required for TOSCA orchestrator (could be a property of the artifact)
‘file’ of this artifact
Metadata of the image, it is not required for TOSCA orchestrator (could be a property of the artifact)
Could move to Vdu.compute
