The “Conceptual Model, KGen Role & Implementation Demonstration” video presents an end-to-end overview of the ONCOSCREEN semantic integration and federated data management approach for colorectal cancer research. The demonstration introduces the conceptual architecture designed to enable interoperability across heterogeneous healthcare and research data sources while preserving institutional autonomy and distributed data ownership.
The video further highlights the role of KGen within the platform, showcasing how semantic technologies, ontology-driven mappings, and metadata harmonization are used to support federated querying and unified access to distributed datasets. It demonstrates how different data models and schemas can be semantically aligned to enable consistent and meaningful data integration across participating institutions.
In addition, the demonstration provides insight into the practical implementation workflow of the Virtual Data Lake (VDL), including metadata extraction, schema-to-ontology transformation, validation procedures, and API-based access mechanisms. The presented workflow illustrates how the ONCOSCREEN platform supports scalable and interoperable data integration while facilitating advanced analytics and collaborative colorectal cancer research in a federated environment.
