This should be "sightings object rethought". While coming up with a proposal, I spotted a different way of thinking about Sightings. In my opinion, the most important thing is determining which STIX object is being sighted. However, there is some other bits of information that is useful: sightings producer and date/time of sighting. Now take a look at the recent relationship object discussions: Relationship Object Discussion: ID  [1]: The ID of the  relationship , a simple random GUID Marking [1]:  The ID of the marking  object  that you should reference Version  [1]: The version of the  relationship ; a simple number to be used with the ID for version control Type  [1]: The “type” of  relationship  being expressed.  (Not sure of how this works yet) Description  [1]: A single simple and short description Source  [1] : The ID of one or more source entities in the  relationship  as a URI (not QName) Targets  [1..N]: The ID of one or more targets in the  relationship  as a URI (not QName) Start  [1]: A timestamp in UTC stating when the  relationship  between the  object s started, or the text 'unknown'. End  [1]: A timestamp in UTC stating when the  relationship  between the  object s ended, or the text 'ongoing', or the text 'unknown'. Reliability/Confidence  [1]: A measure of confidence in the  relationship  using the Information Reliability scale. Producer  [1]:  A simple producer  object  like what John calls out Timestamp  [1]: A timestamp in UTC stating when the  relationship   object  was created. Idea: Could a sighting be a type of Relationship? Relationship Object Discussion: ID  [1]: <GUID> Marking [1]:  TLP Green Version  [1]: 1 Type  [1]: Sighting Description  [1]: Soltra Edge reported Sighting Source  [1] : Soltra Targets  [1..N]: soltra:indicator-<GUID> Start  [1]: End  [1]: Reliability/Confidence  [1]: Producer  [1]:  Soltra Timestamp  [1]: <timestamp> Or is there more meta data we need to collect regarding sightings that a sighting deserves it's own object?
