MARTE — MARTE-AADL Issue 3

[MARTE-AADL Issue 3] The set of new stereotypes provided in the AADL annex of MARTE (e.g., port group, subprogram, data type) seems to show that MARTE (and UML) does not support some AADL concepts. However: a) AADL Subprogram clearly maps to an UML Operation. More refined Operations can be modelled by “Requested Service” (GQAM chapter, p.263). b) AADL Data concept clearly maps to MARTE MutualExclusionResource (GRM chapter) or SharedResource (SAM chapter). The latter includes additional stereotype attributes useful for schedulability analysis. It may be a combination of both. This brings up the question of what the overlap and difference is between MutualExclusionResource and SharedResource. One represents the mechanism to achieve mutual exclusion, while the second is the entity that may require mutual exclusion in the context of concurrent access.

Summary table, most component and associated features representation and property
table have been upgraded and aligned: a) on MARTE issues for ports, b) data
representation, c) data and bus access representations, d) new reference on flow and
mode sections. Non MARTE stereotypes have been removed.
