With testbed 2 we want to stimulate further implementation of the architecture (visualisation, data, calculation interconnected with the fundament) to enable the realisation of a Dutch space for interoperable Digital Twin applications. This testbed focusses on adoption for known components and further research for additional components.
We want to intensify the testbed 1 architecture but also enable stakeholders new to the testbed to participate. We want to address the technical questions of this testbed in use cases with the intention to clarify user questions we have identified. Geonovum, in line with its mission, is keen to get the answers; and it seeks to involve the market to do so. The actual questions and issues to be addressed are described in the testbed document, combined into four topics. A summery of the practicalities of this tesstbed can be found on this page, as well as recordings of the information sessions and minutes of the Q&A's and of course the invitation to tender document.

The testbed comprises five research and three adoption topics:
1 Foundation
- Adoption sub-topic: Catalogues with Interoperable API
- Research sub-topic: Data sharing under conditions

- Research sub-topic: Data downloads
4 Calculation models
- Adoption sub-topic: Making calculation modules interoperable
- Research sub-topic: Model orchestration, status quo
Who can participate?
The tender is open to private and public parties, and to combinations of parties (consortia). In the case of a consortium, there is one party who acts as the contact point and contractor on behalf of the consortium for the tender with Geonovum.
