Re: [cti] Use case for data markings
So here is a real example that is formatted so you can read it, to help illustrate the issue I think Terry is trying to bring up.  NOTE: I left some required fields off for brevity.  In this first example, the marking-definition file is not marked... So that is pretty simple stuff.

{

  "type": "package",

  "object_marking_refs": ["marking-definition--089a6ecb-cc15-43cc-9494-767639779124"],

  "indicators": [

    {      "type": "indicator",      "id": "indicator--089a6ecb-cc15-43cc-9494-767639779235"    }

  ],

  "marking_definitions": [

    {

      "type": "marking-definition",      "id": "marking-definition--089a6ecb-cc15-43cc-9494-767639779124",      "spec_version": "2.0",      "created_at": "2016-02-19T09:11:01Z",      "defintion_type": "isa",      "definition": {        "classification": "CLASSIFIED",        "caveats": []    }  ]

}

Now if I want to mark the marking-definition file, it would be done like (note red text).....

{

  "type": "package",

  "object_marking_refs": ["marking-definition--089a6ecb-cc15-43cc-9494-767639779124"],

  "indicators": [

    {      "type": "indicator",      "id": "indicator--089a6ecb-cc15-43cc-9494-767639779235"    }

  ],

  "marking_definitions": [

    {

      "type": "marking-definition",      "id": "marking-definition--089a6ecb-cc15-43cc-9494-767639779124",      "spec_version": "2.0",      "created_at": "2016-02-19T09:11:01Z",

      "object_marking_refs": ["marking-definition--089a6ecb-cc15-43cc-9494-767639779121"]      "defintion_type": "isa",      "definition": {        "classification": "CLASSIFIED",        "caveats": []    }  ]

}

Now that UUID "...121" points to what?  And how do you share that?  If the indicator is shared but not marking-definitions UUID "...124", then how do assert what you need to know about the indicator. 

I fully get the need to mark a "marking-definition", however, how is that supposed to be done?  And what will work for you?  

Thanks,

Bret
