Next Web of Linked Data at Minnebar9. I chat about open data, "raw data now", JSON-LD and Hydra, and schema.org. A basic high-level overview of what is going on in the open data and semantic web world.

1. The Next Web of Linked Data
@jaymyers
MinneBar 9

2. • Early adopter
• Semantic Web,
Linked & Open
data enthusiast
• Speaker
• BBY’er *

3. Original Web
• Collections of documents
• Users “surfed”
• Created mostly for human consumption

4. Web of Today
• Trillions of web pages
• 5 billion web pages change every day
• 1000x more web pages on the “deep web”
• Over 60% of website visitors are machines

5. Every day we create 2.5 quintillion
bytes of data
(equivalent to 3.4 billion HD movies)

6. Linked Data
“A new form of Web content that is meaningful to computers
will unleash a revolution of new possibilities” - TBL

7. 2009

8. Five Star Open Data
Make your stuff available on the web
Make it available as structured data
Use non-proprietary formats
Use URIs to denote things, so people can
link to your data
Link your data to other data

9. RDF Ontology: FOAF
<jaymyers> <foaf:knows> <kristenwomack>
<kristenwomack> <foaf:knows> <billybob>
A machine can infer that Jay might like to know
Billy Bob

10. RDF Ontology: GoodRelations
<wafflemaker> a gr:ProductOrService ;
<wafflemaker> <gr:category> ‘Waffle_Makers’
“Show me the names of all ‘lightweight’ waffle
makers”
<wafflemaker> <gr:name> ‘Euro Cuisine 8" Heart-Shape
Waffle Maker’
<wafflemaker> <gr:weight> ”2.0"^^xsd:float .

11. dbpedia
Machine
readable
data

12. “Show me music artists whose hometown is
Minneapolis”

13. Hydra & JSON-LD
• Machine-readable vocabulary that can be
used to describe web APIs
• Puts the information back in APIs by defining
small contract that sets JSON structures and
URLs
• Creates new breed of web APIs (powered by
Linked Data) using decentralized, reusable
contracts

14. 2010

15. schema.org
• Common vocabularies that search engines
can understand
• Lower the bar for webmasters to publish
linked data on the web in their HTML
• Improve user experience through data

16. Goals
• Create a web for both humans and machines
• Entice webmasters to make metadata
available through web standards and
structured HTML
• Gain access to the meaning of web sites
• Establish relationships between data that
allow for exploration and discovery

17. Value Prop
“Give us your data in a machine-
readable format and we’ll make
your stuff more attractive in search
results”

18. Looks Like We’ve Got Something Here!
• 15% of all sites contain schema.org markup
• Many major sites
• Adoption by content systems like Drupal and
Wordpress
• Around 1200 object types and growing
(people, places, products, etc)

19. Practical Applications in Search
Yahoo! Related Entities

20. Practical Applications in Search
Yandex Islands

21. Practical Applications in Search
Google Knowledge Graph
Additional content driven
by schema.org derived
data

22. Other Applications
Pinterest Rich Pins
