Doesn't it blend accurate sources and inaccurate sources? Yes, yes it does. The 'intelligence' community has actually been talking about this problem with RDF for years. My understanding is that they use RDF quads (not triples) so that they have an extra parameter to track the source. (it might be that they use something larger than a quad). From what I remember (the conversation was years ago), they have to be able to mark information as suspect (eg, they find that one of the sources is unreliable, then re-run all all of the analysis without that source's contribution to determine if they came to the same result). I don't know enough about the implementation of linked data systems, so if there's some way to filter which sources are considered for input, or if there's any tracking of the RDF triples once they're parsed out. -Joe
