Parsing the XMI Extensions of Enterprise Architect
SDMetrics 2.35 introduces a small extension to the XMI parser. Assume we need to access information such as the author or a documentation string from the XMI extension part of Enterprise Architect. This information is encoded as follows: <uml:Model xmi:type=”uml:Model” name=”EA_Model” visibility=”public”> <packagedElement xmi:type=”uml:Package” xmi:id=”4A3564″ name=”test” visibility=”public” /> </uml:Model> <xmi:Extension extender=”Enterprise Architect” extenderID=”6.5″> <elements> <element… [Continue reading]

Design Quality Metrics for UML2 Profile Extensions
The interchange of UML models between tools via XMI is difficult in practice. This is particularly true for UML models that are extended by UML profiles such as the SysML. In the past, tool vendors often used proprietary XMI extensions to serialize the profile applications, which were not understood by other tools. More and more… [Continue reading]
