Re: [cti-stix] Proposal - Top Level Relationship Object

["Jordan, Bret" <bret.jordan@bluecoat.com>]

So based on everyones comments thus far, I am summarizing to:

• ID [1] [Required]: The ID of the relationship
  
• Version [1] [Required]: The version of the relationship; a simple number to be used with the ID for version control (instead of timestamp)
  
• Type [1] [Required]: The “type” of relationship being expressed.  (Not sure of how this works yet)
  
• Description [0..N] [Optional]: Words about the relationship.
• Objects [2..N] [Required]: The ID of one or more targets in the relationship as a URI (not QName)
• Start_Time [0..1] [Required]: A timestamp in UTC stating when the relationship between the objects started, or the text 'unknown'.
• End_Time [0..1] [Required]: A timestamp in UTC stating when the relationship between the objects ended, or the text 'ongoing', or the text 'unknown'.
• Confidence [1] [Required]: A measure of confidence in the relationship.  
• Timestamp [0..1] [Required]: A timestamp in UTC stating when the relationship object was created.
• Source [0..N] [Optional]: A URL pointing to source of the information that allowed the relationship to be created (not the producer as that is inherently in the ID's). 

Thanks,

Bret
