The time period for which an entity is embargoed. During this period, the entity should not be published or, in the case of a press release, should not be reported on. For open-access journal articles, the embargo duration specifies that period of time during which availability of the open-access version of the article is delayed by the publisher, following subscription-access availability of the published work. The end of the embargo period can be specified by fabio:hasEmbargoDate.
