DefinitionA de jure standard (デジュレスタンダード) is an official standard that a standards body has reviewed and formally adopted following set procedures.
ExplanationStandardization means bringing things such as product specifications and data formats into line with a shared set of rules. International or national bodies whose job is to write those rules are called standards bodies, and ISO (the International Organization for Standardization) is the best-known one worldwide. A fixed procedure runs from drafting through gathering stakeholder comments to approval, and only what passes through it becomes a standard.
AnalogyNot a popularity vote, but like a parliament debating and voting by a fixed procedure: the way the decision is made is itself formally laid down.
Memory hookDe jure is Latin for "by law". Jure belongs to the same "law" family as the English words jury and justice.
