This document describes the MISP taxonomy format which describes a simple JSON format to
|
||
represent machine tags (also called triple tags) vocabularies. A public directory of common vocabularies
|
||
called MISP taxonomies is available and relies on the MISP taxonomy format. MISP taxonomies are used to classify
|
||
cyber security events, threats, suspicious events, or indicators.

NOTE: Changes at the bottom of this file overrides some earlier settings.
|

|
||
Once the style has stabilized and has been adopted as an official RFC style,
|
||
this can be consolidated so that style settings occur only in one place, but
|
||
for now the contents of this file consists first of the initial CSS work as
|
||
provided to the RFC Formatter (xml2rfc) work, followed by itemized and
|
||
commented changes found necssary during the development of the v3
|

formatters.
