Re: AW: AW: What is Riena about? (was AW: AW: [riena-dev] Ridgets)

[Christian Campo <christian.campo@xxxxxxxxxxxx>]

Hi Scott,

All Riena projects will sooner or later have a dependency on  
riena.core, because it contains a number of help classes that we use  
throughout Riena. The Markers are in riena.core and not in  
riena.ui.core for the moment because the navigation model projects  
that we have need to get access to the markers but we didnt want them  
to have a dependency on the UI classes because the NavigationTree and  
the NavigationProcessor is really an abstract concept and by itself UI  
independent.

Maybe we change that in the future but thats the way its now and I  
dont think these four classes do any harm to the riena.core package.  
Like I said all riena projects will have or will have a dependency on  
the riena.core project. No plans to have that any different.

regards
christian
