About Core Business Vocabulary

What is the Core Business Vocabulary?

The Core Business Vocabulary is a simplified, reusable and extensible data model that captures the fundamental characteristics of a legal entity, e.g. the legal name, the activity, address, etc. 


E-Government Core Vocabularies are the starting point for developing interoperable e-Government systems as it allows mappings with existing data models. This guarantees Public Administrations to attain cross-border and cross-sector interoperability.  

The Core Business Vocabulary is one of the Core Vocabularies that have been developed by the SEMIC action of the former ISA² Programme, which is now named Interoperable Europe. The specification is developed in an open process with the active involvement of the SEMIC action stakeholders including: The e-Government Core Vocabularies Working Group (with a total of 69 people from 22 countries, 19 EU and 3 non-EU countries (USA, South-Africa, and Norway), and several EU Institutions and the Directorate-General for Informatics: DG DIGIT.

The latest version of the Core Business Vocabulary can be downloaded from https://github.com/SEMICeu/Core-Business-Vocabulary/releases/tag/v2.0.0.


This specification enables interoperability among people registers and any other ICT based solutions exchanging and processing information about people.
