The MicroArray and Gene Expression (MAGE) group is a project of the FGED Society to develop a standard for the representation of gene expression data from microarrays to facilitate the exchange of information between different data systems.[1] MAGE has in the past worked with the OMG (Object Management Group), which provided a framework for developing, ratifying, and publishing the MAGE-based standards documents. The MAGE standards include a data exchange model (MAGE-OM: Microarray Gene Expression – Object Model) and data exchange formats (MAGE-ML: Microarray Gene Expression – Markup Language; MAGE-TAB: Microarray Gene Expression – Tabular format) for microarray expression experiments.
