Maven artifact and groupId naming

I'm currently in the process of moving some project from Ant to Maven. Conformist as I am, I want to use well-established conventions for finding groupId and artifactId, but I can't find any detailed conventions (there are some, but they don't cover the points I'm wondering about).

Take this project for instance, first the Java package: com.mycompany.teatimer

Tea timer is actually two words, but the Java package naming conventions forbid the insertion of underscores or hyphens, so I'm writing it all together.

I chose the groupId identical to the package ID because I think that's a good idea. Is it?

Finally, I have to pick an artifactId, I currently went for teatimer. But when I look at other Maven projects, they use hyphens to split words in artifactIds, like this: tea-timer. But it does look weird when concatenated to the groupId: com.mycompany.teatimer.tea-timer.

How would you do this?

Another example:

Package name: com.mycompany.awesomeinhouseframework

groupId: com.mycompany.awesomeinhouseframework (?)

artifactId: awesome-inhouse-framework (?)

However, I disagree the official definition of Guide to naming conventions on groupId, artifactId, and version which proposes the groupId must start with a reversed domain name you control.

com means this project belongs to a company, and org means this project belongs to a social organization. These are alright, but for those strange domain like xxx.tv, xxx.uk, xxx.cn, it does not make sense to name the groupId started with "tv.","cn.", the groupId should deliver the basic information of the project rather than the domain.
