POM root Element: project or model?

[Joachim Schreiber <yo...@yos.biz>]

The Docs on m2 web site for the POM shows <model> as the root element. 

In the m2 cvs is a mixture of <project> and <model> elements in the pom.xml
files.

What is the planned name for this element, project or model?

BTW Why not using a namespace declaration (and an online accessible schema
representation of the pom) in the pom.xml?

Cool, I will do this ;-)
Thanks!

If you'd like, you can use the same code Maven does:
maven-model-2.0-alpha-1.jar (you'll also need plexus-utils-1.0-alpha-2.jar)

MavenXppReader reader = new MavenXpp3Reader();
Model pom = reader.read( new FileReader( new File( "pom.xml" ) ) );
(with suitable error handling on the FileReader, of course)

>From that, you have pom.getName(), pom.getBuild(),

Cheers,
Brett

Yes this is not really a problem for m2 ;-)

I was just playing around with the new m2 model. For me the POM is a
repository for Metadata about a project/artifact. I want to parse the
pom.xml files and transfer them to a XTM TopicMap. For XML parsing I very
often use XMLBeans... and XMLBeans needs a schema and xml instances with a
namespace.

In the moment I have created a schema for the new m2 POM and use it with XML
Beans for parsing the POM. Before I give the XML to the parser I add a
science fiction namespace and good ;-)

Yes I know this is just my personal kismet and I can live with it ;-) but
perhaps other schema and namespace aware parsers for examples in IDE's or
Tools may have the same problem.

Just an idea and a report from working with m2. Not a criticism!

It should be project... it is in the process of being changed. Actually,
either is valid, for now.

It's planned to provide a generated schema - however, different
namespaces will not tend to be used inside the POM - we've looked at the
option and preferred to keep it simple, finding no need to add them at
this point.
