Great! 
The next thing we should try to achieve is a common structure. I’ve already started with the first sentence for each Item type. Next I’d like to add Create, Save and Retrieve examples to all Item types (see Location). I think this kind of unity will help users to quickly find what they are looking for.
I’d also suggest to add Links to the JavaDoc article of all Items and Types mentioned.
@lipp_markus you wanna join the effort? The first article is a “wiki article” now, meaning everyone can add content.
