Dear Silvia, > Could sombeody explain what FRBR is? > Sorry if it's obvious to everybody else. Sorry, I agree it is not clear for the ones who do not work on this topic, though I ack Yves to step in the discussion (Yves, come as often as you want here :-)) FRBR: http://en.wikipedia.org/wiki/FRBR or Functional Requirements for Bibliographic Records, a model made by IFLA for the librarians, that is, for describing things you put in a library (in a nutshell). So, FRBR defines 4 abstract levels, namely: work, expression, manifestation, item. Let's take an example: - Work: . w = J. S. Bach’s Six suites for unaccompanied cello - Expression: . e1 = performances by Janos Starker recorded in 1963 and 1965 . e2 = performances by Yo-Yo Ma recorded in 1983 - Manifestation: . m1 = recordings (of e1) released on 33 1/3 rpm sound discs in 1965 by Mercury . m2 = recordings (of e1) re-released on compact disc in 1991 by Mercury - Item: a single exemplar of a manifestation ... your CD, ot mine! So, what Yves said, is that we might want to define a fragment for an frbr:item (i.e. a particular mp3 file stored on your web server) or define a fragment for a frbr:manifestation (i.e. take the 2nd chorus of "Let It Be" from The Beatles, abstracting the encoding version of that, mp3, wav, etc.) Do I well-summarize your point Yves?
