The Gene Expression Markup Language (GEML) is a file format for storing DNA microarray and gene expression data. GEML is an open-standard XML format which enables exchange of data between gene expression databases and analysis systems. GEML stores which data collection methodology was used, without making assumptions about the meaning of a measurement. This enables possible normalization, integration, and comparison of data across methodologies. GEML handles expression profile data and allows scan images and chip layouts (or "patterns") to be easily referenced and tracked. GEML is independent of any particular database schema.
