An Extended Catalog System for the Management of Distributed Urban Digital Twins

Content

The integration of information from distributed sources represents a significant challenge in many smart city projects.
Catalog system are an essential component in addressing this challenge. T4 offers a further development of a catalog service designed specifically for the management of distributed UDTs.

The Key Learnings

Maintaining an Overview With SDDI

To avoid losing sight of the vast amount of data, information, and applications within a city, the creation of a Smart District Data Infrastructure (SDDI) is essential. This is an enhanced version of SDI and a decentralized system of systems from various stakeholders.

Requirements for the Catalog

The catalog contains all relevant metadata, which is managed and provided by different users. For this purpose, the catalog must know and support all categories, be multi-client capable, and ensure that all stakeholders can participate in resources, tools, and applications, as well as edit metadata.

Connection to the Digital Twin

The Digital Twin can also be registered as an entry in the catalog. This can be done by creating an instance of different classes and conntecting it to other entries through the Depends_on linking function.

Advantages Over Previous Developments

Previous developments, such as geoportal of SDIs, are not yet aligned with the requirements of substantial expansion. Catalogs, as a central element of SDDIs, offer a more robust solution than geo data infrastructures, enabling stakeholders to effectively manage distributed resources, instances and Urban Digital Twins across the board.
