In fact, my fear is that we will do just that if we develop BIBFRAME as a "new version of MARC." Sure, we can write programs to turn MARC into triples -- but that won't get us an active place in the linked data cloud.

+1 - a graph full of literals isn't a tremendous improvement over, say, marcxml.

This is apparently what D2RQ does so why don't we fine tune this and we are done? A goodly portion of what I'm reading here sounds more like attempts to add sources of info outside of our libraries (e.g. six different name authority sources) rather than the original facilitation of others coming in to our existing library data. We're supposed to be breaking down the silos, not building new Googles. Seems D2RQ already breaks those silos.

I think this kind of system will work better for popular, not research, public libraries.  I think that because popular public libraries have greater turnover of material and are not preserving older material.  Still, it won't be perfect, but part of what will drive such a decision is a better record display from having the consistent data.  I can't see my ILS trying to reconcile 245 $h and 336, 337, 338 to give me the same icon for type of material, and I can't see BIBFRAME reconciling these different MARC data elements as well.

To use a recent subject of discussion as a simple example, if one starts with MARC-21 data that contains a non standard textual string and a coded relator, the mapping into a semantic model might not preserve the non-standard string.  MARC-21 data using a standard string might map to the same semantic representation.
