OGC Data Exchange Toolkit: Interoperable and Reusable 3D Data at the End of the OGC Rainbow

Standard data models are powerful to enable data interoperability. However, due to their ambition to comprehensively represent a domain, they tend to be over-specified. On the other hand, they allow too much flexibility in implementation and modelling details, to adapt to several use cases needs. The OGC Data Exchange Toolkit intends to overcome the two issues by means of a methodology to define profiles through linked data technologies, operated via the OGC Rainbow. Moreover, attributes are defined to specify the desired object representation requirements, solving the under-specification issue. A template is provided, intended to support manual input of data requirements, generating in turn a human-readable description and a machine-readable input for the profiling tool itself. The profile allows automatic datasets validation against the defined requirements. The prototype is developed and tested on a sample CityJSON dataset.
