Just a remark: why can't I comply with a module's API by just
subclassing it and overriding all its methods? Why do I need an
implementation-less interface for this? (I thought the interface-hype
was initiated to justify Java's disability of multiple inheritance.)

If you ask, I say let's change it to something more commonly used and
more intuitive for newcomers. I'm not sure, however, that either
changing all such names to a new naming style, or introducing
inconsistencies is good. What do people feel about this?

If something structured, it is clear that we will have to parse the date

Hm. If they share a lot, can't we make swissprot inherit from GenEMBL?

Ok, apart from the comments above. Do we really need the interface here?
