Annotation

Annotation: The ever-increasing urgency of solving the interoperability problem is shown. The source of the problem and the reason for the increasing relevance of its solution-the increasing level of heterogeneity of the ICT environment-are shown. It also shows that the interoperability problem exists for information systems of all classes and, consequently, the interoperability technology is a meta-technology with a dual purpose. It is noted that interoperability is the basis of the Single Information Space for any purpose and scale. It is emphasised that the interoperability problem must be solved together with the information security problem. The state of the problem abroad and in the Russian Federation is considered, and concern is expressed that the scale of work in the Russian Federation does not correspond to the importance of the problem. Proposals are made to force the work and reduce the gap.
