Assigning a stable, valid throughout the life cycle object a code can significantly simplify information
exchange both in global communities and within a domain. The article describes the methods of
codification, based on the ontological representation of the domain, on the example of Education and
the Stock Market. Two modules of software need the object’s identification: Core components, or master
data, and roles. Unambiguous identification for core components is necessary to link data about objects
used in different domains or application in order to aggregate core component’s attributes. With
the use of codification systems, it becomes possible to compare similar objects from different systems,
as well as create conditions for the application with future technology as the system of distributed
registry blockchain where the identification of an object has a key role. In the digital economy
there are significant changes in the «Role» module — the count of process participants significantly
expands: suppliers, consumers, and other actors. Some part of transactions can be performed by digital
devices. Identification in this case becomes an important element of business processes. Separate
groups of business process actions require a different level of identification. This understanding of the
identification infrastructure involves all stakeholders into a secure environment creation.
