SummaryThis chapter of the technical design documents address the semantic interoperability challenges when designing the SDG Once-Only Technical System and ensuring its interconnection with the EU Member States' IT systems and EU level systems. Data models were developed to streamline the exchange of evidences, together with a methodology for defining new data models and code lists to ensure the quality of the evidence exchanged between the Member States.
The SDG regulation does not mandate use of (only) structured evidence types and does not provide a mandate to harmonize. The evidence exchange feature documented in chapter 4 of the technical documents consists of a flow of Messages based on the Evidence Exchange Data Model (EDM), which comprises the EDM Request (Request from Evidence Requester to Evidence Provider for certain data or documents) and the EDM Response (Response from Evidence Provider to Evidence Requester to deliver the requested data or documents). The Query Model is fully documented and supports document-based queries. The Exchange Data Model of evidence exchange is a light-weight generic mechanism to support the exchange of any type of evidence. It facilitates the automated exchange of unstructured and structured types of evidence.
The content of this chapter is structured in the following sub-chapters:
