Martin Moore, writing in the IdeaLab for Mediashift, identifies and explains the value of linked data for a newsroom.
Linked data isn't necessarily well-defined generally. Moore clears it up: " Linked data is a way of publishing information so that it can easily -- and automatically -- be linked to other, similar data on the web." Thus, a reference to Paris is linked in such a way as to make clear it's Paris, France, and not Paris, Texas or Paris Hilton.
The benefits Moore sees are significant: better SEO recognition, better site location, more opportunity for you and others to build services around links, bait for the firewall, and so on.
But the overall point Moore is making is the importance of layering content and making the journalism newsrooms produce more valuable as a resource. It's another initiative newsrooms will need to take to play in the sphere.
