The document discusses conceptual modeling for geoscience data. It describes how geoscience data is large, diverse, complex, volatile and interconnected. Conceptual modeling can help communicate data structures, simplify understanding, and enable data validation and system development. Benefits of conceptual modeling include aiding communication between stakeholders, automatic database generation, project management and transforming models into ontologies to improve data integration and discovery. Examples discussed include models from the British Geological Survey and case studies of conceptual modeling for the BExIS data management system.
