Drupal and the Semantic Web
Jan 15, 2015
Data by itself is simply a collection of numbers. It only becomes meaningful when we weave it through context. A context of relevance that creates information - provides insight, creates solutions and solves problems. The Web gives us a fabric of connectedness, but if the data isn't substantiated semantically, the information we create isn't very useful. By building effective web assets using platforms like Drupal, we build ways to solve problems across the spectrum from local to global. We not only build the Web the way it was meant to be, but we also build it to support a commons across community, enterprise and government for generations to come.

What are we really seeking?
Data → Information → Knowledge
WorldWideWeb (www version 1.0)
Tim's Boss: “Vague, but exciting.”
Web
The plan: semantic.
It became: Glorified Brochure.
Hand-coded HTML.
Horrible HTML editors.
Human readable
Web 1.0
Human readable? Yes.Machine readable? Not quite.
Human understandable
Guess who?
All on one page?
It must be about him
...and his picture
...and his work
...and his email
...and ...
Massive network
Metcalfe's law
Utility = square of the nodes
How do we keep track?
Web servers and Web browsers
Connections
DialupDSLWi-Fi4G...
Network connections – neutral (we hope)
Relationships
“Content may be king, but context is everything.” - @sameerverma

Too many relationships
How do we keep track?
Taxonomies.Ontologies.
Yes, those are two different things.

Hashtag as an ad-hoc taxonomy.
“Folksonomy.”
