Generic data models for Semantic e-Government interoperability: Literature Review

Interoperability of e-government systems is suggested to increase transparency, efficiency, effectiveness, and customer service in the public sector. Generic data models are often seen as a way for achieving especially semantic interoperability. To assess how the contemporary data models support semantic e-government interoperability, we reviewed literature on data models suggested for the public sector in light of four features: standard modelling language, entity-relationship modelling, vocabulary for data exchange and methodology. The review contributes previous research by introducing a four-feature framework for assessing capability of e-government data models to enhance interoperability and by providing an up-to-date review of the generic data models for this purpose.
