Recommended way for accessing POM data

Hi,

I'm currently trying to access some Maven related data in my Netbeans plugin.

This iscludes:
* is ist a Maven based project at all? (my wizards rely on a Maven based project structure)
* Group ID
* Artifact-ID
* Version

I found a way using NBMavenProject, however the related module has only a limited accessability. Thats why I'm assuming this is not the recommended way. 
(similar to using internal API)

What is the recmmended way for geting the required information?

I'm not trying to manipulate the exosting POM, I'm just trying to get the information.

TIA,
