An Interoperability Framework can be defined as the overarching set of policies, standards and guidelines which describe the way in which organisations have agreed, or should agree, to do business with each other. An Interoperability Framework is, therefore, not a static document and may have to be adapted over time as technologies, standards and administrative requirements change.Administrations that provide electronic services (eServices) are faced with the same situation, they need to elaborate a set of agreements on a large number of issues, considering organisational, semantic and technical aspects. For example, when administrations exchange data, they must ensure that each party shares the same meaning of the data (semantic interoperability): for instance, when referring to 'price', do we mean the actual price or the price per item? The European Interoperability Framework addresses these issues in order to facilitate the interoperability of eGovernment services at pan-European level.
