Simple question, simple answer. Use lists between parties (or other

implement proportionality within the lists in one quite primitive

also proper party internal proportionality.
It seems easy enough to generalize, at least given how proportional
ordering methods have been mentioned lately:
- Each voter votes for a list, and can rank this list if he wants to.
- Once the election is done, the authority calculates the number of
seats given to each party, as well as a proportional ordering for
each party.
- Each party gets the top n candidates on its proportional ordering,
where n is the number of seats allocated to that party.
Yes. Use of proportional ordering is not a requirement though. One
could as well count the n proportional representatives directly at one
go. (And in elections with open list tradition one could require that
all votes are to individual candidates in any case => one or more of
them ranked.)
A more complex version might give the party itself some say in the
ordering; e.g. the voters' ballots may count as 75% of total while
the predefined party order counts as 25% of total. If the
percentages are 0 and 100 respectively, you have ordinary closed list.
(Yet another approach would be to have the party order count as a
fixed *number* of ballots - if few people bother to rank, the party
order is strong so that it can counter the noise of the few ballots
that have been submitted, while if many people do, there's less
noise and so the err-default rank should matter less.)
One approach if one wants to give the party some say when determining
the representatives would be to allow the party to complete the short
votes with the predetermined party ordering. In that case the voters
could determine the representatives 100% if they so wish, and the
party could have more say if the voters don't care.
