I need to explore the Metamodel of SysMl, I have tried with make new emf project and add the following xmi file http://www.omg.org/spec/SysML/20120401/ISO-80000-1-SysML.xmi.
But I could not open it using emf editor, because of missed package, for example in this file the following namespaces is needed
<xmi:XMI xmlns:xmi="http://www.omg.org/spec/XMI/20110701"
xmlns:mofext="http://www.omg.org/spec/MOF/20110701"
xmlns:uml="http://www.omg.org/spec/UML/20110701"
xmlns:sysml="http://www.omg.org/spec/SysML/20120322/SysML">
Have you an idea how I can import this namespaces, or how I can explore SysMl metamodel?
I have installed Papyros in Eclipse
