Language is an important factor of economic development; translation and localisation are necessary for the overall progress and economic development. In the European Union, language is key and English is no longer sufficient for the development of a common language policy; they are now striving to achieve a situation where every European would speak at least two foreign languages. In science, the number of publications in the researchers’ mother tongues has increased and publishing in English is no longer a sign of prestige.
Metadata has been used in libraries since the days of card catalogues. With the automation of libraries and the development of MARC formats, metadata schemes have gained an important role in the implementation of different functions, common to library practice. In the 1960s, the technology of magnetic tapes inﬂuenced the development of MARC records and the ISO 2709 standard.
