Semantic Web glossary
As my own explorations of the Semantic Web progress I will be incrementally building up a Semantic Web glossary. My current glossary is currently only a placeholder and merely a list of terms and phrases used when writing about the Semantic Web, but eventually my intention is to flesh out meaningful definitions for all of those terms.
Please let me know of terms you feel I should add, as well as other Semantic Web glossary efforts.
