Data Exchange APIs
This building block facilitates the sharing and exchange of data (i.e., data provision and data consumption/use) between data space participants. An example of a data interoperability building block is the ‘Context Broker’ of the Connecting Europe Facility (CEF), which is recommended by the European Commission for sharing right-time (near real-time) data among multiple organisations.
Facilitates data sharing and exchange between data space participants, ensuring semantic interoperability of data and data sources.
- OGC APIs and OWS building blocks for spatial data exchange including Features, Things, rasters, Observations and many more.
- Semantic support is provided by the Vocabulary hub that is hosting OGC specific models but also some domain models, mapping between various ontologies and profiles.
A smart city needs to calculate its environmental performance on the basis of a collection and aggregation of information about all the sustainability projects in its urban environment. This information is shared by different stakeholders, who use different formats and semantics to report CO2 emissions and other indicators. The building block enables syntactic and semantic harmonization of the different data sources, as well as effective exchange of data using a common data exchange API to enable the calculation of the KPIs (key performance indicators) needed.
OGC suite are technical level interoperability standards, both abstract and encodings. They can contain transport, encodings and data models. Combining these based on the specification is a challenging and error-prone process. In addition, generic standards often require extensions (e.g. specific additional structures) and profiles (subsets and compilations). Ultimate interface or data model definition shall be maximally reusing existing data models, support translations between others, while preserving the semantics and provenance of data. To enable semantic representations that will enable both logical and ontological model matching, the OGC Definition Server was developed. It is maintaining OGC standards ontologies models and some domain-specific ones that bridge to the abstract secifications models.
- INDEX - Industrial Data Excellence We have used it in the Index project in the Smart Manufacturing use case. It enables the secure exchange of data among manufacturing machines that deploy heterogeneous interfaces and communication protocols. There is a description of the project https://www.dimecc.com/dimecc-services/index/
To ensure interoperability between all data space participants, the technical measures need to be continuously maintained. This includes general agreements and domain specific models. The continuity model provides measures for change, release, and version management.
- Domain Data Standard: It provides the syntax and semantics for data exchange and data sharing on different levels, in a specific sector or domain. To achieve specific goals, multiple standards can be used in combination.
The Telekom - Data Intelligence Hub is intended to serve as a digital connection between companies and be both a source for commercial data acquisition and open data. The platform offers users tools for analysis, acquisition, exchange and processing of data. Industry experts get the possibility to develop new business models, data-driven products or services. It is relevant for companies of all sizes and industries but also for universities, for example, that develop models for the combination of data and algorithms to attain new insights.
- Formal definitions are not always easy to adapt, which is not the gap cannot be filled on the adopter's side, but the thresholds if high.
- The governance administration is internal, while it is not clear if itcould be better aligned to the Access & Usage Policies building block.
- Implementation of the Data Usage and Accounting, and Publication & Marketplace Solutions could be helpful.
- Provenance and traceability support is not stable.
- NGSI-LD is being adopted worldwide as a minimum interoperability mechanism for data exchange by cities. For example, in India has been adopted by the Bureau of Indian Standards.
