Abstract

This new work item proposes a solution to increase interoperability of the DPP system (in consideration in Module 4 in WG4). Interoperability is critical to enable the seamless exchange of DPP-based information between heterogeneous systems. This NWIP follows the approach of the standard interoperability layers and proposes the following aspects in this regard: Technical Interoperability • Secured exchange protocol (e.g., HTTP(S)) that can be transported over firewall systems and the public internet infrastructure (aligned with module 5 of JTC24WG4) • Data formats • Serialization of data with standardized media type (e.g., JSON) • Potential compression approaches (e.g., Open Packing Convention - ISO 29500-2, CBOR) • Review data act regulation Article 33 “minimal requirements on interoperability in data spaces” on relevance Semantic Interoperability • Allow data structuring with standardized or established data modelling languages (e.g., XML, JSON, SHACL, rdf, owl, JSON-LD) and semantic modelling September 2017 Section Details • Define a generic semantic structure for models and data dictionaries that allow unrestricted definitions of the EC according the SREQ • Define architecture for repositories for the data dictionaries • Avoid sector specific ontologies - allow parallel and unrestricted usage of ontology definitions by commission in delegated acts with horizontal abstract layer as general as possible (technology-, ontology- and domain agnostic) Organisation Interoperability • Interoperability with existing technology frameworks • Enable both human access AND machine (software) access • Align with work of WG 1, 2 and WG 3 and all modules of WG 4 of JTC 24 Out of scope • Data exchange protocols (see NWIP “data exchange protocols”) • Database definitions for backend services (dpp is technology agnostic) • Sector specific ontology definitions • European standard(s) on unique identifiers • European standard(s) on data processing and data formats • European standard(s) on data carriers and links between physical product and digital representation • European standard(s) on access rights management, information, system security, and business confidentiality • European standard(s) on data storage, archiving, and data persistence • European standard(s) on data authentication, reliability, integrity • European standards on Application Programming Interfaces (APIs)
