Reproducible information is important in science, medicine and other professional fields. Repeating the same experiment with measurement should yield the same information as the result. This original information should also be transported digitally in reproducible form, as a globally well-defined sequence of numbers. The article explains that "Domain Vectors" (DVs) with the structure "UL plus sequence of numbers" are well suited for this purpose. "UL" is an efficient link to the online definition of the sequence of numbers. DVs are globally comparable and searchable and have other important advantages. It is concluded that DVs can fill an important gap in the digital representation of information.
