Conceptual models are frameworks that provide a high-level representation of the essential components of a system or domain. In the context of data management ontologies, conceptual models serve as a blueprint for organizing and linking different ontologies to ensure effective data integration and interoperability. These models enable ontology developers to use combinations of different ontologies and vocabularies in the field of data stewardship. They also facilitate the mapping and alignment of ontologies, enabling data to be shared and reused across multiple systems and applications. The overlaps.md document summarizes identified overlaps in described ontologies. The errors-inaccuracies.md document describes errors and inaccuracies found during the analysis of described ontologies. The table shows the number of connections between described ontologies.
