Rule consist of these blocks: [ ...] [ ...] Action is 'allow' or 'deny'. Operation is an object service verb: 'get', 'head', 'put', 'search', 'delete', 'getrange', or 'getrangehash'. Filter consists of : Typ is 'obj' for object applied filter or 'req' for request applied filter. Key is a valid unicode string corresponding to object or request header key. Well-known system object headers start with '$Object:' prefix. User defined headers start without prefix. Read more about filter keys at github.com/nspcc-dev/neofs-api/blob/master/proto-docs/acl.md#message-eaclrecordfilter Match is '=' for matching and '!=' for non-matching filter. Value is a valid unicode string corresponding to object or request header value.
