At http://bibframe.org/demos/ there is a link said to be "A collection of Library of Congress MARC records representing the diversity of resources found at the Library". Closer examination of the sample shows that all the resources appear to be physical resources. Examination of the Library of Congress website suggests if also holds a range of digital resources. Could http://bibframe.org/demos/ please be updated to either remove the diversity claim or (preferably) with a more diverse sample. Ideally the more diverse sample would include (a) a digitised resource with a parallel physical resource (b) a born digital resource (c) a digital resource in a format with no equivalent physical format (an RDF data file; a global climate model dataset; etc). If the Library of Congress doesn't generate MARC for such resources, I'm sure that members of the list can locate or generate suitable exemplars. cheers stuart -- Stuart Yeates Library Technology Services http://www.victoria.ac.nz/library/
