Using a subset of the <span class=SpellE>Ecore</span> -profile (see below) and the model we described in the “Getting Started with -UML2” article [1] (the ExtendedPO2 model, shamelessly “borrowed” from the EMF -“bible” [2]) as an example, we’ll look at what’s involved in creating some of -the more common elements that make up a profile. For each type of element, -we’ll first explain the creation process using the sample UML editor and -explore how to accomplish the same thing using Java code. Then we’ll look at -what’s involved in applying profiles and stereotypes to models. The ExtendedPO2 -model is shown below.</p> - -<p><!--[if gte vml 1]><v:shapetype id="_x0000_t75" coordsize="21600,21600" - o:spt="75" o:preferrelative="t" path="m@4@5l@4@11@9@11@9@5xe" filled="f" - stroked="f"> - <v:stroke joinstyle="miter"/> - <v:formulas> - <v:f eqn="if lineDrawn pixelLineWidth 0"/> - <v:f eqn="sum @0 1 0"/> - <v:f eqn="sum 0 0 @1"/> - <v:f eqn="prod @2 1 2"/> - <v:f eqn="prod @3 21600 pixelWidth"/> - <v:f eqn="prod @3 21600 pixelHeight"/> - <v:f eqn="sum @0 0 1"/> - <v:f eqn="prod @6 1 2"/> - <v:f eqn="prod @7 21600 pixelWidth"/> - <v:f eqn="sum @8 21600 0"/> - <v:f eqn="prod @7 21600 pixelHeight"/> - <v:f eqn="sum @10 21600 0"/> - </v:formulas> - <v:path o:extrusionok="f" gradientshapeok="t" o:connecttype="rect"/> - <o:lock v:ext="edit" aspectratio="t"/> -</v:shapetype><v:shape id="_x0000_i1142" type="#_x0000_t75" style='width:581.25pt; - height:407.25pt'> - <v:imagedata src="article_files/image001.emz" o:title=""/> -</v:shape><![endif]--><![if !vml]><img border=0 width=775 height=543 -src="article_files/image002.gif" v:shapes="_x0000_i1142"><![endif]><o:p></o:p></p> - -<p>As described in the EMF book, some of the attributes of certain <span -class=SpellE>Ecore</span> elements cannot be expressed directly in UML™.

This project will serve as the container for the profile that we’ll -create using the UML editor.

Now, to -follow along with the programmatic approach to creating profiles, we’ll assume -that you’ve created a Java class (named, say, “IntroductionToUML2Profiles”) in -which you can write some code to construct our sample profile.
