RDF as a general information model is applicable to many uses (many of which
we never even thought about)
Common data representation and architecture drives down (technical / social)
costs
Facilitates serendipitous interoperability - breaking down the barriers of
domain knowledge
When "Anyone can say anything about anything", who you trust is important
Beneficial to solving interoperability in Open (rather than Closed) systems
Closed systems are becoming more and more Open - addressing these issues now
seems cost effective in long run
