The MISP taxonomies directory is publicly available [@?MISP-T] in a git repository. The repository
|

contains a directory per namespace then a file machinetag.json which contains the taxonomy as

described in the format above. In the root of the repository, a MANIFEST.json exists containing

a list of all the taxonomies.

The MANIFEST.json file is composed of an JSON object with metadata like version, license, description, url and path.

A taxonomies array describes the taxonomy available with the description, name and version field.
