Analytical Information Markup Language is the developing XML standard for analytical chemistry data and is currently in pre-release form. It is a combination of: A highly flexible Core Schema that defines XML tagging for any kind of analytical information; A set of Technique Definition Documents. These XML files, one per analytical technique, applying tight constraints to the flexible core and in turn are defined by the Technique Schema; Extensions of Technique Definitions are possible to accommodate vendor- and institution-specific data fields.
