Hi Patrick, [ISBNs] Okay, I understood that. ISBNs are not reliable. (I wonder how Amazon and eBay deals with that, but maybe this is another story). I always thought ISBNs == GUUIDs, My fault. > We have some helpful identifiers for books, but perhaps not completely > reliable as a global identifier. How's that? Sounds good, but what are the GUUIDs? Don't tell me that we could merge book X with book Y if they have the same author or the same title in Wikipedia.... > Given the amount of time and energy that has been devoted to the sub-set of > subjects that are books, does that give a clue as to what more ambitious > projects to give all subjects a single unique identifier are going to wind > up? Well, one question remains: Where are the subjects? Where are the global identifiers? If there are no global identifiers, all attempts to create a topic map from MARC are pretty useless. If neither ISBNs nor any other global identifier are given, who could we assume that we talk about the same subject? Best regards, Lars -- Semagia <http://www.semagia.com/>
