Hi Karen -- the background on the selection of the Core elements is here: http://www.rda-jsc.org/docs/5chair15.pdf

We've been told the core elements were selected as core because they rank in high value according to the FRBR user tasks (that value matrix is at 6.1 in the FRBR document: http://archive.ifla.org/VII/s13/frbr/frbr3.htm#6): "The core element set reflects those attributes and relationships which attained a “high” rating for the user tasks defined by FRBR (see 2.1) and FRAD (see 2.2)."

Coming out of the work from the Task Force on Cost/Value Assessment of Bibliographic Control (http://connect.ala.org/node/106017), Joyce Chapman and I (at NCSU) and Barbara Tillet (at LC) are working on a project to map the RDA elements more explicitly to user task value. Stay tuned ...

Can anyone point to documents that describe the reasoning behind the

chronicled in the comments documents.

Also, has anyone made up a list/table of core elements by format?

Quoting Rosa Matthys <rosa.matt...@bibnet.be>:

Hi


We are studying RDA and find it sometimes difficult to understand why
some fields or subfields are a core-element in RDA.



For instance:

- Statement of responsibility relating to title proper > in some
descriptions is the repeating of the name of the author in a specific
field of 'statement of responsibility' not relevant, all information
can be provided in the access point (name and relator code or term).
Only in the case that there is more information in the publication
than the cataloger can record in the access point, a 'Statement of
responsibility' can be necessary.

- Place of publication: in the world of music and film with
international labels as publishers, a place of publication is not
necessary for identification. There are enough other identifiers in a

the description.



Do 'core-elements' cover all materials, or is it possible that
something can be core for one kind of material and not for another?

If a core-element is not necessary for your public, is it still
possible to be RDA-compliant?

The RDA documentation says that catalogers SHOULD include all core
elements. Is "SHOULD" an advice or is it a requirement?
