AIXM 5.1.1 is now released as a minor update of the AIXM 5.1 version. The main purpose of this update is to migrate the UML model to a new modelling environment (Sparx EA). Although this change should not create any change in the AIXM Schema, the AICM Change Control Board (CCB) decided to publish it as a separate version in order to avoid any risk of an unintentional changes being introduced by error. On the same occasion, a number of small editorial corrections, alignment with the latest xlink schema and updates of some lists of values have been made. Full details about AIXM 5.1.1 are available from the Versions menu.

On the occasion of the AIXM 5.1.1 release, the www.aixm.aero Web site has also been completely re-designed and refreshed. We hope that the new Web site organisation facilitates that work of both AIXM developers and users of AIXM systems.
