What is the business value of Linked Open Data? What is the business case that drives you to support / invest / develop into yet-another-platform and what will it do for your business/library/museum/archive/store-front? Anecdotal, academic and one-off examples aside, why should you care?
"Re-use data, re-use vocabularies", this has been the battle cry for Linked Open Data and Semantic Web enthusiasts since day one. Formally, the W3C Government Linked Data Working Group has published a Working Group Note on the matter where they state that "Standardized vocabularies should be reused as much as possible to facilitate inclusion and expansion of the Web of data". What seems to be a reasonable point of vue has been pushed a little bit too strongly of late.
On August 4, 1914, Great Britain declared war on the German Empire for, among a long list of complex reasons, violating Belgian Neutrality as they attempted to invade France through Belgium.

It was really the British Empire declaring war on the German Empire and that the Dominions and the British Indian Empire would support Great Britain directly was no more surprising than Austro-Hungary supporting Germany.
One of the uncomfortable questions that is often repeated with projects generating linked open data is "So, you've created a database. Now what?".

But how do you actually use the data and does it actually ever get used?
