Following its initial success, the new release of the e-Government Core Vocabularies provides a generic approach for reusing the Core Vocabularies in order to design new data models and align with existing ones. The approach is syntax-neutral, i.e. independent of any technical representation, and can be used together with other methodologies for creating information system data models, information exchange data models or linked data models.

The handbook illustrates two use cases of the Core Vocabularies:

1. to design new data models based on the Core Vocabularies, and
2. to create mappings between existing data models and the Core Vocabularies.  

 

 

Different types of data models can benefit from the existence of the Core Vocabularies and the provided mappings to standard syntaxes:

• Design of a new domain data model. In this case, the Core Vocabularies can be used as the context-neutral starting point. Such new domain models, based on the Core Vocabularies, can also be used when designing a complete information system data model. This will ease the interoperability, smoothing the eventual integration with external collaborative business processes (interoperability-by-design).
• Design of an information exchange data model. The Core Vocabularies and the mappings to standard syntaxes can be used to create technical guidelines for information exchange specifications.

Data models that map to or extend the Core Vocabularies guarantee a minimum level of cross-sector and/or cross-border interoperability that can be attained by public administrations.
