Hiya,

How about a bloom filter. It is very effective for 'is item in set of items' type query. Not sure what scale you thinking of. At the BBC we use bloom filters to prevent duplicate votes for things like strictly come dancing. Even after millions of votes it can identify a duplicate vote without having to store a log oh ever IP address which has ever votes.

The issue is similar, instead of storing. List of all preferences a use has made (which is of variable size) instead store a bloom filter off unique items of the set. The filter will be the same size for all users making scaling easier. 

I only have a rough idea for how they work but perhaps this is a good use case. Just a stray though. :)

Yes the thin we need is how to encode the preferences, so we cna evaluate what preferences are supported and what are not

I did n;t make my reason for sharing this clear. It was to give an
overview of the various standards that may be of interest to us.

AS to how to do it - do you mean gathering and using preferences?
