The City Catalyst project aims to enhance better urban management, implementing the concept of sustainability and enabling semantic interoperability in cities in Smart Cities. Therefore, this paper presents a contextualization of Smart Cities and an overview of the remaining gaps that persist in terms of semantic interoperability. An introduction is also made at the level of ontologies. The NGSI-LD model is presented at the level of the generalized information referential and then, more specifically, the ontology layer. At last, scenarios were built, taking into account the context of the project, and, through these, tables were prepared with terms that constitute the glossary of terminologies. The work culminates with the mapping of the NGSI-LD using Neo4j which will serve as a basis for the Smart City systems to communicate with each other.
