D4.2: Set of requirements for interoperability of Identity Management Systems

FIDIS DEFINITION AND WHAT IS ENABLED

Definition and what is enabled

Libon sees interoperability as a way to exchange information and services between systems and different stakeholders without effort from either side. An interoperability framework is comprised of policies, standards and rules describing the arrangements that organisations agree to “talk” to each other.

Libon sees interoperability at three levels:

• Syntactic: structure of data 

• Semantic: common definitions of terms 

• Transactional: ability to use systems decentralised 

Libon also states that interoperability requires actions at three levels:

• Organisational: defining rules and responsibilities of the various actors involved 

• Semantic: creating agreement between various parties on meaning of terms 

• Technical: creating standards for presentation, processing and exchange of information

Timmers also refers to three levels: Semantic, organisational and technical. For Holosi and Martin highlighted the importance of semantic interoperability across countries.
