# Element names and the shared namespace

Classes and enums carry the `Attack` prefix, so they can be imported beside other vocabularies, and each class extends a lmodel/stix class with the `Stix` prefix. The slots keep the keys MITRE's data writes, so data validates unchanged: STIX's keys come from the stix modules, and ATT&CK's are `x_mitre_*`, with `tactic_refs`, `channel`, `field` and `related_asset_sectors`. Enum values keep MITRE's spelling, such as `Field Controller/RTU/PLC/IED`.[^about.md] `.linkmllint.yaml` leaves permissible values out of the naming rule for that reason.[^linkmllint.yaml]

A host imports the adapt copy beside LOKF's schema and other copies, and LinkML merges them into one namespace. No class, enum or type shares a name with LOKF's or with the released copies of nine neighbours. The copy shares the keys stix's own copy shares with in-toto, slsa, spdx and oscal, because STIX's property names stay.[^readme.md] `tests/test_schema_rules.py` pins those lists, checks that the copy holds stix's copy whole, and pins the four ATT&CK keys without the prefix.[^test_schema_rules.py]
