The Microarray Gene Expression Data Society is an international organization composed of computer scientists, data analysts, and biologists "that aims to facilitate the sharing of microarray data generated by functional genomics and proteomics experiments." Hosted by the European Bioinformatics Institute, this website connects to information about six major Data Society workgroups (e.g. the Ontology Working Group, the Reporting Structure for Biological Investigations Working Groups, the Data Transformation and Normalization Working Group). The Data Society website also offers a News Archive; several downloadable publications from the past few years; a number of PowerPoint presentations from past Society meetings; contact information for Society Board Members; and links to information about upcoming and past Society meetings.
