That is the question. They could as well also be


We have 3 different kinds of "zip".

Implementation "zip" -> Archive Type "zip" -> File Exension "zip"

Now it depends on how we want to handle this at the factory level.
Right now we only have one implementation per archive type - with the
implementation names being the same as the types. So we still have the
luxury of making up our minds about this.

One thing that also crossed my mind was a possible relation to file
extensions and mime-types. Maybe it would make sense to have a
ArchiveType with meta information? I don't know. I might as well just
over analyzing this :)

Rant over and out.
