<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I believe that it is possible to access
the position information for a specific attribute in a specific aspect, and I
have done that in the past. Unfortunately I was not able to locate a code
snippet that I could send over to you. As far as I recall you could define
position as a “registry” attribute in your UML class diagram
(generated from MetaGME2UML – you will have to hand modify the generated
UML class diagram). If you have multiple aspects then GME stores position as a
string in the registry node somewhat like this “Aspect1(100,34),Aspect2(150,95),…”,
you can look up the registry node in your GME model to see how specifically it
is stored. Using UDM DS-API you should be able to access this string, from that
point on it should be manageable –</span></font></p>
