Re: [cti] Relationship object - name property
That is a good point.  These should probably just have a single value.

An important consideration here is that the current field, “name”, has only one value. “labels”, on the other hand, supports multiple values. Should relationships be allowed to have more
 than one label (e.g.,  Threat Actor A is [“related-to”, “member-of”] Threat Actor B) or just a single label/name?

 

I can see it working both ways, just wanted to point out that this is about more than just name vs. label.

We should be consistent across all TLOs.  Relationships are a "special" TLO class (the "Edges" of the "Vertices") so there may be a basis for a different data model.  However, can't readily think of one and
 barring suggestion of same, would argue for consistency.

All, 

 

In STIX 2.0 we are using the labels property of the object to capture the "object type" data. For example, in STIX 1.x we had "indicator type", in STIX 2.0 we are putting that same data in the "labels" field on the Indicator object instead
 of having a property called "indicator_type".  We can not use "type" as it is already being used in the model.

 

So the following objects all have these vocabularies that represent the type of object it is:

Threat Actor Type == Threat Actor Label Vocab == Threat Actor Object -> labels property

Malware Type      == Malware Labels Vocab     == Malware Object      -> labels property

Tool Type         == Tool Labels Vocab        == Tool Object         -> labels property

COA Type          ...

Incident Type     ...

Report Type       ...

Indicator Type    ...

 

 

 

So in all of these cases we are using this pattern of putting the "object type" in the labels fields.  There is one exception to this rule though... For the Relationship Object we are putting the "relationship type" (or the relationship
 verb) in the "name" property.  I just wanted to shed some light on this and see what the community thinks of this.

 

 

Thanks,

 

Bret
