Re: [p2-dev] Categories

So... the category structure has to be independent of the IU.
When figuring out how to represent it, using an IU as convenient. However, a category has never been intended to be installable (see https://bugs.eclipse.org/bugs/show_bug.cgi?id=229301). I realize representing it using an IU is misleading to us programmers. The UI knows that it's not truly installable, and it does play "tricks" to merge content from different repos.

The UI present in the IDE is not the only one that need to play tricks here. All code that deals with the categories will need to do the same. Our service for instance, will need a lot of special code to cater for this. All other code that deal with p2 in the future, will also need to handle this kind of IU's in a special way.
