Re: [EXT] Re: [cti] [EXT] [cti] Location as a Top-Level SDO
The only use-case I have heard for a location SDO is the ability to allow a third party to say they think this threat actor for example is also in this other location.   To allow for this use case, you would need either have the location be an SDO or you
 would need to use a note or opinion object.

I would ask that if location is an SDO, then other properties probably should also be made SDOs.

Yeah +1 to Pat…we’re a CTI org, let’s not maintain a database of geolocations.

 

More generally I also agree w/ Allan that this doesn’t really impact the SDO question. Either you:

 

Have the library and duplicate it in the embedded types

Have the library and reference it by UUID (if we generate STIX UUIDs for it)

Have the library and copy it into the referenced types (if we don’t generate UUIDs for it)

 

It would be nice to enumerate these types of scenarios and see how we can deal with each of them in each approach. I talked to Allan and I think he has the beginnings of that
 document started, I’ll get with him to push it to Google docs so we can all look over it.

My .02:  If we're building, publishing, maintaining our own Geo-Location Data, we're doing something wrong.  This is one wheel we do not need to re-invent...again just my .02.

So if we were going to do this, we would probably need to build a library of locations by country and regions and publish them as a Committee Note and hope people just use the them for locations
 at the granularity of a country or group of countries.

You are assuming that we don't create a repository of "standard" location SDOs for things like continent and country names - IE the things that people would want to share in
 the first place. Which, I don't see why we would not do this, seeing how we're doing it for things like CAPEC.

 Location a TLO, we would have to mandate that people update the “_ref” fields to move an SDO, not the Location itself.

Interesting point.  Which effectively means that if you create a

relationship to a location, that location should be one you own, not

one that was created by someone else (unless you can trust the creator

not to do what you just described)...

This means that by definition, there will be many Location SDO's for

the same location to prevent this from happeneing...
