UML PROFILE FOR SAVECCM - Research

SaveUML profile
Base classifier: Port
Tagged values:
• External : String. A label mapping the port to external entity, in case a port is an
external port.
Constraints:
[1] NumberOfStereotypes: see the SaveAssembly constraint [6].
[2] OwnerComponentStereotype: see the SaveCombinedInPort constraint [2].
[3] PortConnections: see the SaveCombinedInPort constraint [3].
[4] PortConnectionStereotype: see SaveCombinedOutPort constraint [4].
[5] PortsExternal: see the SaveCombinedInPort constraint [5].
[6] PortsInterfaces: see the SaveCombinedInPort constraint [6].
6.4 Using SaveUML profile
The profile specification provided in previous section is a general profile
description and needs to be implemented in a design tool in order to be used for a
concrete model design of SaveCCM models in UML.
6.4.1 UML CASE tool
Among various CASE tools available, IBM Rational Software Modeller (RSM)
was chosen as the best tool for this purpose.
Within a SaveUML project a fourteen existing UML tools were analysed, with
several requests that were taken into consideration:
• Support of UML 2.0 component model (this was a major limitation with
most free tools).
• UML profile support. This includes using UML profiles when modelling
user models, but also the possibility of creating UML profiles.
• Importing and exporting user models in XMI (XML Metadata Interchange
[XMI web]) based files.
After the analysis it was concluded that IBM RSM fulfils all requests and that it
is suitable for this work. Therefore, within this thesis, SaveUML profile was
implemented using IBM RSM tool and released as an epx file (epx is a profile file
extension used in RSM).
6.4.2 Applying stereotypes to user model elements
In order to apply SaveUML stereotypes to a model element, first the SaveUML
profile must be applied to the model (for information on applying UML profiles to a
model see RSM help or [SPusr 08]).
