The profile for schedulability, performance, and time is partitioned into a number of sub-profiles, profile packages dedicated to specific aspects and model analysis techniques. At the core of the profile is the set of sub-profiles that represent the general resource modeling framework. These provide a common base for all the analysis sub-profiles in this specification.

The supplied Real-Time Profile package reflects this structure, through its sub-packages:

Each sub-package contains a set of stereotypes and tag definitions as defined in the UML Profile for Schedulability, Performance, and Time Specification (version 1.1, January 2005). All of the stereotypes have been linked with appropriate model item types and tag definitions, which can be viewed through the properties of each stereotype. Each Tag Definition has had its data type specified and published; this can also be viewed through the Tag Definition properties.

Descriptions of the profile packages and their contained stereotypes are included in the Description properties of these items. Further information can be obtained from the UML Profile for Schedulability, Performance, and Time Specification downloadable from the OMG website. It is likely that you will need to refer to this specification to fully understand the concepts represented by some of the stereotypes and tags defined within this profile.
