The usual technique that moves in this direction is to use numeric ids.
An example of such an id is:
http://purl.org/obo/owl/APO#APO_0000018
and the idea is that the next id will be #19, etc. These ids are not
guaranteed to be unique and their non-uniqueness creates a host of
problems. I think that this format is popular because the ids are
somewhat more memorable than unique ids would be.
On the other hand, if you want your ids to be truly unique there is a
standard for this and there is an associated java implementation [1].
Protege supports a method for generating the ids of new entities based
on such unique identifiers.
