This thesis, developed in collaboration with Magneti Marelli
Powertrain S.P.A., shows architectures, requirements and
implementation rules concerning safety-related systems according
to the new normative ISO26262 on functional safety in the
automotive area and the new AUTOSAR 3LSC architecture standard.
These documentations have to be used by Magneti Marelli for
different purposes, such as checking the condition of its system
safety level and to update its documentation. This thesis shows
the representation of the overall documentation previously
mentioned (knowledge description), in a way to define an abstract
documentation level useful for several purposes. This abstract
level is defined with XML technology (XML, XML schema, XPath,
XPointer, XLink, XSLT) that is a simple manner to describe
information.
