Most of published today electronic journals, as well as printed-on-paper, are human-oriented, not a machineoriented. At the same time, there is every reason to believe that in the foreseeable future scientific publications will focus primarily on the input in information search (intelligent) system with inter-machine interface. This, in particular, explains the ever increasing use of XML-type languages, which in principle, can not only take into account the specificities of different subject areas, but also to increase efficiency in the structuring of the automated processing of articles and other documents in the indexing systems. It is clear, of course, that without building a complete ontological description of the domain under study, use XML to semantic structuring is as limited as using LaTeX source, which, as one know, being the presentation language, contains the semantics only indirectly.
The Editorial Board of Russian Journal of Earth Sciences since its foundation has paid great attention to the introduction of modern technologies of electronic publishing in the practice of editorial preparation and publication of the Journal, actively participating in the development of such technologies. Starting with volume 12 (2012), all the articles in the journal are published along with the journal format in PDF, also in HTML5 format, and more strict XHTML format, and EPUB3 format for electronic books. Articles in these formats are generated using ELXpaper software package developed at the GC RAS.
