答复: RE: [tosca] One question about Namespace Alias and URI.

Hi  Yuanxing

 

In tosca-simple-profile-yaml, the namespace Alias is needed because it relates to tosca_definitions _version.

In tosca-nfv-profile, as we discussed and agreed, the tosca_definitions _version value will always set to the namespace Alias of tosca-simple-profile-yaml to represent a specific TOSCA grammar version used in the template, so it is not needed to create a new namespace Alias for tosca-nfv-profile.

 

In general, the conclusion is that in tosca-nfv-profile, it will only specify a namespace URI and a namespace prefix.

 

Regards

shitao

Hi,

 

It confused me and I wonder why "alias" was removed. If I understand correctly, the alias is necessary.

If we remove the alias from the spec, what shall we use to define the tosca_definition_version below?  Would that be the whole URI? That's too long.

 

tosca_definitions _version:      tosca_simple_profile_for_nfv_1_0

Hi Shitao,

 

Based on our latest namespace discussions, I believe the “alias” is no longer needed. You would only ever use the fully qualified URI (from the Target Namespace) or the prefix.

Subject: [tosca] One question about Namespace Alias and URI.

 

 

Hi all,

 

I noticed that namespace URI and alias in TOSCA NFV Profile Specification is defined.   And we use the alias in the sample template as below.  On yesterday's nfv call, we decided to remove the  alias. Is that alias the same one referred in the following table?

 

Alias	Target Namespace	Specification Description
tosca_simple_profile_for_nfv_1_0	http://docs.oasis-open.org/tosca/ns/simple/yaml/1.0/nfv/1.0/	The TOSCA Simple Profile for NFV v1.0 target namespace and namespace alias.

 

tosca_definitions _version:      tosca_simple_profile_for_nfv_1_0
