You can attach named paths to objects and then labels these. Here is my
first try, seems to work:
\startMPinclusions
input metaobj;
\stopMPinclusions
\startreusableMPgraphic{labeltest}
newCircle.a(btex A etex);
newCircle.b(btex B etex);
a.c=origin;
b.c=a.c+(1cm,2cm);
ncline.b(a)(b) "name(ab)";
ObjLabel.b(btex $a\rightarrow b$ etex) "labpathname(ab)",
"labangle(0)";
drawObj(a,b);
\stopreusableMPgraphic
\starttext
\reuseMPgraphic{labeltest}
\stoptext
For more options for labels, see page 54ff of the metaobj manual.
Greetings,
Eckhart
