The Uniform Data Access Layer (UDAL), a central component within the FAIR-EASE project, is designed to revolutionize how researchers access, integrate, and utilize diverse scientific datasets. FAIR-EASE prioritizes FAIR (Findable, Accessible, Interoperable, Reusable) principles to ensure that data becomes a powerful enabler of scientific discovery and informed decision-making. The UDAL concept brings a modular and re-usable approach to choosing and using data in data processing workflows. It materializes as a software package that users can use in their pipelines. UDAL serves as a middleware layer, offering a standardized, user-centric framework for data access. By bridging the gap between complex infrastructures and researchers, UDAL simplifies data retrieval, integration, and usage.
