Two groups working together - New SRO

[sheetlaand]

Hello,
Currently, when two groups works together, we can't find a valid relationships to explain this behavior.
Our wish is to be able to create these two SROs:

• a "collaborate-with" relationship, to explain if a group works with other(s) group(s).
• a "subgroup-of" relationship, when a group is just a part of a bigger group.
  Does it makes sense for you ?
  Thank you !
  Best regards,

Relationship types specified in the specification are "suggested" only. You and the community you share with can agree on any additional relationship types that you want to support.

Since using consistent relationship type names is advantageous, it will probably make sense to consult with the STIX community for new suggested relationship types in future releases.

Hi Rich,
Yeah, we know that it is "suggested" only, but our wish is to discuss with the whole STIX community about new relationship types. :)
