Re: [cti-stix] external-references keywords
It does have some overlap, in the sense that you can pass a URL, but the primary purpose of the artifact object seems to be actually providing the content (either as a URL to download it
 from or as an encoded payload) while this type seems mostly about referencing other content (I would not expect a tool consuming these references to automatically download the content at the URL). So they seem differentiated enough to me to not worry about
 it...

FWIW, external_reference seems to have a lot of overlap with the Cybox Artifact object ( see

https://docs.google.com/document/d/1DdS-NrVTjGJ3wvCJ7dbSlhYeiaWS6G6dOXu2F3POpUs/edit#heading=h.3py86bmi9w34 )

Could there be some unification here?

Hi everyone,

I think these four keywords would cover all of the external reference details. I’ve including some examples below. Can anyone think of some external reference that couldn’t be specified using these keywords?

Rich

external_references: array of {

description : string

external_id: string

source: ov?

url: url

}

Any combination is legal

Examples:

CAPEC:

[ { “source”: “capec”, “external_id”: “capec-550” } ]

CAPEC with URL

[ { “source”: “capec”, “external_id”: “capec-550”, “url”: “http://capec.mitre.org/data/definitions/550.html”} ]

APT1:

[{ “description”: “APT1 report”, “url”: “http://intelreport.mandiant.com/Mandiant_APT1_Report.pdf”}]

VERIS:

[{“source”: “veris”, “external_id”: “00C84D6A-CDB8-4A5B-A1A6-0D75A65274D7”}]

Jira:

[{“source”: “jira”, “external_id”: “TAB-1370”, “url”: “https://issues.oasis-open.org/browse/TAB-1370”}]
