This is the kind of solution I was worried about, a list of lenght N needs N*(N+1) / 2 inferred triples, which quickly becomes unmanageable, eg. MusicBrainz has containers with several thousand members. Admittedly thier not collections, so the problem is not as bad, but its a reasonable thing to want to store in a collection. - Steve
