Comment 15 for bug 128394

The analysis that I did is at:
  http://openlibrary.org/about/frbrization
This proposes some possible structures for the creation of Work records (Work in the FRBR sense). The CC project has a slightly different need: the creation of Expression records. This is because copyright operates at the FRBR Expression level (the Work level is more abstract than the law addresses). We need to discuss whether we need both Work and Expression levels in OL, or if Expression will be sufficient.
