Report and catalogue on the ICT data integration and interoperability

This deliverable first identifies open standards for data vocabularies and data models in the smart city domain including, but not limited to: FIWARE, INSPIRE, Transmodel, ISO/IEC 30182 and BSI PAS 182. Corresponding API specifications such as BSI PAS 212, READY4SmartCities, oneM2M, W3C SSN, Dublin core, API styles (REST, SOAP, etc.), and already implemented API libraries such as CitySDK and TK Forum, as well as existing partner APIs will be integrated. Moreover, the report provides an assessment of the potential of using IOTA and other Distributed Ledger Technologies (DLTs) (e.g. Ethereum, bitcoin, litecoin etc.) as a mechanism for data transfer and fall-back security and exchange mechanisms for ensuring data integrity and confidentiality (connected to Task 1.2).
