Abstract One of the biggest challenges in building sustainable smart cities of the future is skill management and development. Developing the digital skills of the municipalities’ workforce is crucial for all occupational profiles and specifically for those that are actively involved in the development and operation of digital services for a smart city. In this context, the current paper presents a semantically enhanced cloud-based IT approach which integrates learning pathways with competence management of personnel working as management and technical employees in a smart city municipality. The proposed approach combines a rule-based expert system with a semantically rich infrastructure in order to map skill gap diagnosis to required learning objects and, thus, to contribute in developing appropriate competences of smart city professionals. The semantic infrastructure of the learning platform consists of an ontology which encapsulates the appropriate knowledge and a rule-base for modeling the steps of an employee training process. In order to achieve efficiency in competence management the semantic model has been transformed into a relational database schema, which is further utilized by the system for the execution of useful queries. The paper presents the key modeling artifacts of the proposed approach and the architecture of the implemented CMUTE system. Keywords Competence management . Semantic web technologies .

1 Introduction With the number of smart cities increasing rapidly, the market for smart city information and communication technology (ICT) is already on a strong growth curve. This growth is expected to continue while more cities will engage in smart infrastructure projects (Kumar et al. 2020). A smart city is a well defined geographical area (municipality), in which high technologies, logistic and energy production cooperate to create benefits for citizens in terms of well being, intelligent development, inclusion and participation and environmental quality (Dameri 2014). The municipalities’ workforce is the backbone of the successful initiative of a smart city (Avdeeva et al. 2019). Current and municipality professionals and newcomers need to acquire new ICT skills and attitudes for meeting the set challenges. According to the report of Economic and Social Council of United Nations on “Smart cities and infrastructure” (UNCTAD 2016), which studies future trends up to 2030, one of the five main challenges that will be encountered in the implementation o
