7. www.edikt.org 7 e-Science Application Binary Data File BinX – accessing legacy binary data  The Problem: –Many binary data files –Applications must “know” the data format –Binary data formats are machine-specific BinX Library  The Solution: –Write a “stand-aside” format description in XML –Provide a library to  Interpret the description  Provide file access across different machines –Build higher-level services BinX file describes binary file structure simulations

8. www.edikt.org 8 AstroBinX – format transformation Binary Data File Spectral Analysis Application Binary Data File 3D Image Data Mining Application FITS data format VOTable data format BinX description BinX Utilities BinX Library Data format transformations based on XML descriptions  Even when we try to agree, we disagree  Multiple data format standards require conversions

9. www.edikt.org 9 OSAGE – Applying Computer Science  Extend the Edinburgh Mouse Atlas –Data model to describe multiple species –Support scientific collaboration via data sharing DB2 DB CS theory Data Access Services  Computer Science theory and best practice –Data modelling to efficiently relate images and text –Flexible data annotation and versioning with XML
