Cornerstones: yes. Nothing else: no. This is an evolving area, and I expect new technologies and approaches to appear that a larger 'Web of Data' should work with in some way or other...

For me, the boundaries are blurred, I must admit. To take one example, the URI-s provided by the LC for their authorities provide a fixed and stable reference for a number of subjects that people use to annotate, say, their bibliographic entries but also other online documents. Entry points like these to the cataloguing world would become an essential element for a number of applications. Projects on cultural heritage, to take another area, that has become really important in the past few years (eg, the Europeana project) would/should/could also rely on such references.

Tom Baker or Dan Brickley (cc-d) are more familiar with these areas, they may have more specific examples.

Wow. I cannot necessarily describe that in terms of explicit functions. But... I would like to have an easy way to access library catalogues all over the world, to find the most up-to-date information on, say, Bach's Hohe Messe (to take a non-book example). Using Linked Data, I should be able, actually, to _integrate_ that various data on that work that is around the globe, including the list of recordings, maybe the reviews, etc. Much of this type of data is in libraries already but, today, the only source people have is to go to, say, Wikipedia (or its RDF dump, DBPedia) and similar sites. Lots of information are missing out today.

Of course, if the digital data is also available, then a reference to that is also of a great value (although I am aware that this is bound to access control issue).

Mind you: this is my personal opinion. Others in the community may have other priorities...

Of course. I would expect some sort of a translation service, so to say. You may know that there is a work going on mapping RDB-s to RDF; essentially, providing some sort of an on-the-fly translation, at least in some cases, to SQL data but seen through an RDF goggle. Maybe something similar is conceivable for that legacy data, but I may be optimistic...
