Ah. good point - a sensible third way. Apologies for missing it, I'm a relative SQL novice. However, if you fetch the tags along with the ways using a join, given that there are potentially many tags per way - couldn't you end up with considerable duplication of the way data in the query result? I suppose one would have to profile both the join method and my local storage method to see which had better memory and time performance.
