Technologies of cross-border digital services in the EU, formalized ontologies and blockchain

Abstract

The article is devoted to the development and operation of cross-border digital services in the EU and the use of such technologies as formalized ontologies and blockchain.  In the world, there is an unprecedented increase in the coherence of global flows of goods and data, which have long become trans-boundary. As a result of these processes, the world has broken up into a multitude of economic associations, the most famous of which is the European Union (EU). This process is strengthened by the so-called fourth industrial revolution, characterized by the through digitization of all assets and their integration into the digital ecosystem. Cross-border access to, use and exchange of data is essential for economic growth in the digital age. Ontology is a taxonomic hierarchy of lexical terms and their syntactic and semantic relationships for representing the structure of organized knowledge. The ontology, together with the blockchain, establishes a binding infrastructure for the trust ecosystem, with effective coordination of trust and data sources, and the provision of infrastructure for the development of distributed applications. Together, these two technologies can serve as the basis for building systems in global information exchange, with the main focus on blockchain and ontology technology structures, key technology principles, standards and basic protocols that ensure transparency of use.
