18. 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

23. Introducing Triples
Nodes & Links
follows

• Quite simply: Subject, Predicate, Object
• gives us the ability to describe entities in a way that is
machine readable
24. 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,
July 23, 1861

people much smarter than I were already on it. earlier in 2009, the father of the World Wide Web, Tim Berners-Lee, was taking his message of Linked Open Data to the streets. How we can build a web of data... sounds familiar... and it seems to worked out the first time... From a web of documents, to a web of data\n
and that web of data is already growing rapidly...\n
What if we begin to apply this to the vast amounts of data at libraries, archives, and museums?\n
\n

\n
--Our data and databases have been organized in tables\n--which works, but only to a point\n
The World Wide Web is much more like a graph, and the ability to link to disparate datasets relies on our ability to understand data as nodes and links in a graph\n
