Hi I still have problems with this proposal. The point is that on Linked Data every dataset can be used as a reference for creating descriptions, be they corresponding to "bibliographic records" or "vocabularies" on the *traditional* library environment. To a great extent something like Worldcat can be used as a reference dataset for creating descriptions in other datasets. Linked Data-wise, there's not much functional difference between LCSH and Worldcat, then: they're just big bags of URIs you can re-use. Note that using "dataset" alone was not the only option we discussed in Cologne: in fact we liked (and perhaps better) expressions like "organized dataset" or "reference dataset" (or "organized reference dataset" ;-) ) which capture this authority aspect better.
