Subject: Relationship object - name property


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.
