This specification of the EAST ADL 2.0 is based on the EAST-ADL developed in the EAST EEA projectand has been further refined and harmonized with on-going modelling appraches in the automotiveindustry. It presents the modeling infrastructure, i.e. how the modeling elements should be represented inthe language and the UML representation. For each package a usage example is provided.The EAST-ADL 2.0 is harmonized with AUTOSAR.The metamodel and UML profile of EAST ADL 2.0 is defined in two steps: A domain (automotive)metamodel is defined, capturing only the domain specific needs of the language, without adding the UML2details. The basic concepts of UML are used for this purpose, such as classes, compositions andassociations. Based on the domain metamodel, a UML2 profile for the domain metamodel is defined,specifying stereotypes with properties and constraints.Comments on the content of this document are welcomed, and should be directed to .Please download the latest available specification and the XMI file ready for use in UML2 tools from the website.
