- Make fields and methods private where possible
- Add missing Javadocs
- Remove @throws Javadocs (all other languages don't have throws, and it doesn't help much documenting them)
- Use camel case for metaData
- Remove initializing to default values (null, 0, false) because that's anyway done automatically
- Remove @Override to let it compile with JDK 5
- Mark as 'work in progress'
