Table 1. The evidence and analysis for semantic interoperability. lTechnical interoperability Technical interoperability refers to that two or more ICT systems, or applications can appropriately provide data communication standards, exchange data and perform a given task without additional operator intervention (Ec.europa.eu, 2012). For this kind of interoperability issues, the Chief Information Officer Branch (CIOB) considered: Evidence 1. “SOA is a standardization of their interfaces.” 2. “The initial set of standards will cover key areas such as registering new services, how to discover reusable services, service mediation, service negotiation and other interoperability issues.” 3. “Departments are therefore asked to keep these principles in mind when planning, defining, implementing or changing business services or any of their supporting processes or technical components.” Analysis The pieces of evidence demonstrate that CIOB has developed standards to guarantee interoperability of services. However, the case does not contain specific interfaces and protocols for information and service transmission. Table 2. The evidence and analysis for technical interoperability.
