I'm still new with FRBR too, so take this with a grain of salt.

  ----------------------------------------------------
  work1           = a speech title and creator
  expression1     = performance place and date
  manifestations1 = text

  Relationship: manifestation1 [isPartOf] work2
                (parts details = volume, issue, pages)
  ----------------------------------------------------
  work2           = academic journal
  expression2     = academic journal volume, issue
  manifestation2  = text (pages, etc.)

  Relationship: work2 containsPart work1
  ----------------------------------------------------

That's the same thing you said (I think),
just more verbose. To me, that looks right.

The main problem that I see it, though, is that an article in a serial CAN 
be considered a work all by itself - it doesn't take a huge leap of faith 
to make that association. But, I rarely find myself think of scenes in a 
movie as individual, stand-alone entities: it's difficult to just pick 35 
seconds of a movie and say "this stands alone".

"this stands alone" seems to be a required assumption of FRBR, though they 
do mention "aggregate works", and that may be key to what we're trying to 
solve. If a movie is considered an aggregate work of images (it is, 
technically, frame by frame), then we've suddenly got logic on our side to 
take a 35 second piece of scenery and call it a work (or a "part").

  ----------------------------------------------------
  work1           = swimming scene with Kari Wuhrer
  expression1     = 15 seconds of filmed footage.
  manifestations1 = film

  Relationship: manifestation1 [isPartOf] work2
                (parts details = duration)
  ----------------------------------------------------
  work2           = Final Examination (movie)
  expression2     = Final Examination (YYYY; movie)
  manifestation2  = Final Examination (DVD)

  Relationship: work2 containsPart work1
  ----------------------------------------------------
  work3           = Poison (movie)
  expression3     = Poison (YYYY; movie)
  manifestation3  = Poison (DVD)

  Relationship: work3 containsPart work1
  Relationship: work3 sharesPart work2
  ----------------------------------------------------

Is that we're you're getting at?

I had no responses to my similar query about parts in FRBR, but I think 
your mapping is a lot clearer that whatever gobbledygook I sprouted off to 
them. If the above is where you were heading, let me know and I'll pop it 
over to the FRBR list and face the silence again.
