From a reddit-comment:
stupid question on "semanticweb". How do I actucally get data? It says library of congress is on 'link-web-data' now. If I want to get a book name by ISBN (using LOCs 'linked data') how would I do that?
Is there a website for the standardize format of link-data? Are there APIs available?
Also how do I cross correlate link-data? Say Amazon also had a link data set (or other "publisher"). How do I correlate ISBN numbers between Amazon, LOCs, the patent office, etc... to verify the integrity of such data. Lots of stuff on goggle is inaccurate, but that is "ok" because people are verifying it. But with an application, you need a way to insure the data is correct and what you are actucally looking for.
