# lmodel/stix

lmodel/stix renders STIX 2.1 as LinkML modules under an umbrella, with classes and enums carrying the `Stix` prefix.[^lmodel-stix] Each ATT&CK class extends a class of it, such as `StixAttackPattern` for a technique. This schema's adapt copy holds every name of stix's own copy with the same keys and IRIs, so a host imports this copy in place of both.[^readme.md]
