Going from Tables to Graphs
• nodes and links in a graph
Going from Tables to Graphs
• As computing power increases, the ability to build more and more complex graphs becomes a reality.
• Human vs. Machine readable

Triples for machines
• triples can be serialized in many different ways, including Resource Description Framework, RDF/XML, RDFa, N3, Turtle, etc, but they all describe things in the <subject><predicate><object> format.
• of course, we need to be consistent and predictable for machines to understand us.

“Early on Saturday morning last while off Point Lookout three negroes came to the ship in a canoe from the Virginia shore. They say they are free, but have no free papers, and assign as a reason for running away that they were required to fight. I have also on board two slaves taken from the Virginia shore by the late Commander J. Ward; they say they belong to Mrs. Stewart, a widow, residing near Mathias Point. I respectfully request instructions in relation to all these people.”
-Capt. S. C. Rowan, aboard the U.S.S. Pawnee, to Gideon Welles, Secretary of the Navy,
