– DTDL is the Digital twin Definition Language developed by Microsoft. This language is based
on top of json-ld and the existing Fiware data models are converted in this format.

8.3 MIM 3: Ecosystem transaction management

8.3.1 Goals

Scaling of IoT- and AI-enabled services across many cities and communities requires easy and
low-risk access to suitable urban data sources that are already deployed in cities and communities
today – on terms that are reasonable and set by the inhabitants and their representatives. This is
the aim of the MIM.

Europe is already developing a digital single market for the region and is looking at extending it
to other areas with free-trading agreements such as Japan. Other countries and global regions are
doing the same and the ultimate aim would be to have such a digital market extending worldwide.
This would allow easy and low-risk access to relevant and available local data, solutions and other
resources so that services, and solutions already deployed in other places can easily be scaled
to reach mainstream deployment. The use and re-use of the data would lead to new revenue
streams, incentivising the infrastructure owners to share data, analytics, services and/or solutions in
infrastructure partnerships based on key technology enablers – always on the terms and conditions
of the people who live in those territories where the virtual service provisioning is taking place.

With a set of such marketplaces established, all parties would be able to co-create applications,
solutions, services, and guidelines on top of the common data models and standardized APIs.
Facilitating this ecosystem of providers and consumers would lead to sustainable business models
and fair mechanisms for sharing and the provision of fair compensation and to reduce the risk in
investments.

8.3.2 Capabilities

Such a digital marketplace would realize standardized exposure of data and data sets guaranteeing
security and privacy by design. The marketplace would also realize access to services that build on
these data and transfer it to knowledge, intelligence and information for the consumers.

The marketplace would need to provide the following six capabilities:

– catalogue management;

– ordering management;

– revenue (sharing) management;
– SLA management;

– quality management; and
