Issue 11402: concept of "resource" (marte-ftf)
Source: THALES (Mr. Sebastien Demathieu, sebastien.demathieu(at)thalesgroup.com)
Nature: Uncategorized Issue
Severity: 
Summary: The General Resource Model of MARTE seems to define the concept of "resource" both at the instance and classifier levels. For instance, the GRM::Resource stereotype extends both InstanceSpecification and Classifier.

The SwResource stereotype defined in the Software Resource Model of MARTE specializes the GRM::Resource stereotype. However, reading the SRM chapter, it seems that its use is much more focused on description of classifiers (to characterize properties or behavioral features for instance) than instances.

In that context, does it make sense to apply a SRM::SwResource stereotype or one of its subclasses (for instance SRM::SwSchedulableResource) on an instance specification? Note that it seems to be legal given that SRM::SwResource specializes GRM::Resource, which extends InstanceSpecification.


I would be pretty handy to do so, in order to describe a resource platform model provided in input of a scheduling analysis.


Resolution: Complete the paragraph 7.3  with the rules for the default values of attributes of the stereotypes for instance of classifiers also stereotyped.
Revised Text: Add the following paragraph to section 7.3:

When a stereotype is applied on an instance, and provided it can be also applied on classifiers, the value of the attributes not explicitly assigned in the annotation of the instance are taken in principle from the defaults in the profile stereotype definition, but they might be overridden by those in its corresponding classifier, if it happens to be annotated with the same stereotype.

Hello all,

The General Resource Model of MARTE seems to define the concept of "resource" both at the instance and classifier levels. For instance, the GRM::Resource stereotype extends both InstanceSpecification and Classifier.

The SwResource stereotype defined in the Software Resource Model of MARTE specializes the GRM::Resource stereotype. However, reading the SRM chapter, it seems that its use is much more focused on description of classifiers (to characterize properties or behavioral features for instance) than instances.

In that context, does it make sense to apply a SRM::SwResource stereotype or one of its subclasses (for instance SRM::SwSchedulableResource) on an instance specification? Note that it seems to be legal given that SRM::SwResource specializes GRM::Resource, which extends InstanceSpecification.


I would be pretty handy to do so, in order to describe a resource platform model provided in input of a scheduling analysis.

Please let me know what you think about it.

Thanks,

Sébastien
