The interoperability method will help you create and maintain the semantic interoperability of information, i.e. data processing where meaning in flows of data remains the same. The consistent use of concepts makes services easier to plan and understand. Using existing code sets and data models in your own system development is cost-effective and improves interoperability between the systems of different actors. Interoperability platform consists of terminologies, reference data and data vocabularies.
Terminologies tool is used to collect, maintain and publish common terminologies of public administration. Data modelers may use the tool to define terms and relations. Terms, their definitions and even visualization of relations between the terms are publicly available for everyone interested.
The Reference Data tool is a technical platform for collecting and sharing common public sector code lists and reference data. The code lists and their language versions are up-to-date, reliable, browsable to everyone beyond sector limits and downloadable to one's own use. Using common code lists enables interoperability in statistics and between IT systems.
The Data Vocabularies Tool is a service for managing and publishing core component libraries and application profiles as linked data models. Core components are data specifications for harmonizing information used jointly by different actors. Application profiles reuse the existing core components and international linked data recommendations for describing semantics of the information structures to support interoperability of information systems.
