Re: [p2-dev] Issue running p2 director

Categories are a necessary concept. However I think the UI presentation allowing to "install a category" leads ppl to install too much because they don't drill into the categories (see for example on the galileo site) or when a category is not created to have to be fully installed then it confuses people (e.g. imagine a categorized p2 repo for EPIC).
The other mechanism that has been proposed by Henrik and Thomas is one of tagging, but I'm not quite sure how this relates to categories.

I also think the category is a good abstraction. If the category is created with the idea of possibly installing whatever may be under it what is wrong with that? However if there is a better way to do this then I would use that.

I've found that installing a category IU using the director does
pretty much what you'd expect.  But it looks to me like it's a bug
rather than a feature that this works; when you click on a category in
the UI, the category's IU is not installed, only its children.  When
you install a category using the director, the category IU is
installed.

IMO it would be helpful if the director let you install a category,
in the same way as the UI.  Whether that means both install the
category IU or neither does, I don't know.

It may not be helpful with the categories presented by the eclipse.org
update sites, but it's helpful with the categories we present in our
product.
