I see no point in duplicating information here. operator and brand are not required. Branch name, if known, should be in the branch tag and branch number in the ref tag.
Again I see no point in duplicating information here. brand is not required. Branch name, if known, should be in the branch tag. Operator (local branch owner) is usually unknown.
Again operator (local branch owner) is usually unknown. I think the sub-brand is more appropriate to be part of the branch tag. e.g., “Sufersal Deal Ben Yehuda”
