“…Furthermore, none of the tools we are using will be able to natively handle these data. We have previously conducted a study on versioning in this context [57], and found that the versioning capabilities in CityGML 3.0 [38,58] would satisfy the versioning requirements of the (investigated) city applications. Therefore, we made the pragmatic decision that it is most economical to wait to implement versioning in 3CIM in a later version, possibly based on CityGML 3.0.…”

Three-dimensional city models are increasingly being used for analyses and simulations. To enable such applications, it is necessary to standardise semantically richer city models and, in some cases, to connect the models with external data sources. In this study, we describe the development of a new Swedish specification for 3D city models, denoted as 3CIM, which is a joint effort between the three largest cities in Sweden—Stockholm, Gothenburg, and Malmö. Technically, 3CIM is an extension of the OGC standard CityGML 2.0, implemented as an application domain extension (ADE). The ADE is semantically thin, mainly extending CityGML 2.0 to harmonise with national standards; in contrast, 3CIM is mainly based on linkages to external databases, registers, and operational systems for the semantic part. The current version, 3CIM 1.0, includes various themes, including Bridge, Building, Utility, City Furniture, Transportation, Tunnel, Vegetation, and Water. Three test areas were created with 3CIM data, one in each city. These data were evaluated in several use-cases, including visualisation as well as daylight, noise, and flooding simulations. The conclusion from these use-cases is that the 3CIM data, together with the linked external data sources, allow for the inclusion of the necessary information for the visualisation and simulations, but extract, transform, and load (ETL) processes are required to tailor the input data. The next step is to implement 3CIM within the three cities, which will entail several challenges, as discussed at the end of the paper.

“…Both of these limitations could be resolved in a later version of 3CIM, if it is based on CityGML 3.0. This new version of CityGML introduces a new versioning mechanism [57], as well as the possibility to model logical spaces [38].…”

“…The problem highlighted on the additional information is that it requires a substantial restructuring of the technical solution and work processes. In addition, the increasing complexity of the database implementation increases with the number of versioning features included (Eriksson et al, 2021).…”

From consistency to flexibility: Handling spatial information schema thanks to a middleware in a 3D city modeling context

Twinning elements of reality gains a growing interest in support of decision‐making, learning, and simulations: a single and shared model should provide a unique integrative basis for managing assets of any replica of the real world. From a technical viewpoint, sharing and opening information requires both an exchange format and a high degree of freedom and flexibility. It should allow an important number of users to manage this information, to modify it, etc. Storing and manipulating spatial information concerning the urban built context currently focuses on ensuring consistency thanks to relational databases and predefined schemas. Following a paradigm shift from a relational database to a NoSQL database, a schema validation middleware is proposed to improve the flexibility of storage by conceding a share of its consistency. The flexibility improvements thus provide users a common basis that is able to evolve all along the lifecycle of their models and applications as required for twinning things. It allows users and their applications to take advantage of new storage features such as common: versioning, partitioning, prioritization, applications profiles, etc. The middleware and their new capabilities are illustrated thanks to the CityJSON encoding and its simplified schema for a document‐oriented database.

“…On the other hand, the term version often means different instance models resulted from simultaneous, distributed modeling operations [113]. In this paper, variants are instance models representing the same realworld object in a different manner while versions are instance models representing the real-world object at different times in terms of temporal snapshots of the real-world object [99,114]. Different variants/versions are caused by instantiating different schema models (Figure 5) or instantiating one schema model differently (Figure 9).…”

“…Another example is checking the consistency of two information models to communicate model modifications. For instance, consistency checks after the handover of building information (e.g., IFC) to a city model (e.g., CityGML) [99] or in the field of railway infrastructure [100]. The application-oriented perspective on information integration based on the described categories corresponds to research in the field of "BIM-GIS Integration".…”

Information models from the domains Building Information Modeling (BIM) and Urban Information Modeling (UIM) are generally considered as information silos due to their heterogeneous character. These information silos can be bridged through linking where corresponding objects are identified and linked subsequently. However, whether two objects are considered as corresponding might depend on the scenario for which the links are created. The dependency of the link creation and the scenario refers to the term contextual linking and is analyzed in this paper with respect to building and city models. Therefore, different situational aspects influencing the link creation are discussed. Afterwards, the issue of contextual linking is demonstrated based on three different integration scenarios. In summary, this paper has three major outcomes: First, this paper introduces an application-oriented perspective on information integration and emphasize the role of the application when linking heterogeneous information models. Second, this paper shows that linking heterogeneous information models from the domains BIM and UIM at instance level depends on the scenario. Third, the results of the discourse about contextual linking serve as a framework supporting the design and development of artifacts for linking heterogeneous information models from the domains BIM and UIM.
