About 5 years ago I wrote my MSc thesis in CS on a Semantic Web related topic (searching the SW). What a mistake. At that time SW meant things like ontologies/syntax vs. semantics/RDF/RDFS/DAML/etc and the W3C kept coming out with more and more complicated specs without any big player implementing or pushing these standards/ideas. As they say, it was "academic". To my knowledge, it still is.
Is this because the semantic web is completely unattainable, or because the definition keeps shifting (e.g. todays "normal web techniques" are yesterday's "semantic web")?
