Some (recent) Open Data Initiatives

• Making Public Data Public (UK): More access to Ordnance

Survey maps from next year, http://bit.ly/3qTU9s

• Open Data Network (GER): Founded in October 2009,

Berlin, http://opendata-network.org/

• data.gov (US): increase public access to high value,

machine readable datasets, http://www.data.gov/

data.gov.uk

• Open Data Commons: set of legal ‘tools’ to help provide

and use open data: http://www.opendatacommons.org/

Some (new) Linked Open Data

Initiatives

• Linked Data Research Center: appointed to drive and

lead the linked data research and development,

http://linkeddata.deri.ie/

• data.nytimes.com: 5,000 people subject headings as

linked open data under a CC BY license,

http://data.nytimes.com/

• GoodRelations: standardized vocabulary for product,

price, and company data, http://purl.org/goodrelations/

• oeGOV: Use small OWL ontologies to model recovery and

deploy across all government, http://www.oegov.org/

From Open Data to Linked Data

heavily inspired by Leigh Dodds, Talis

http://www.slideshare.net/ldodds/web-integrated-data

© Semantic Web Company – http://www.semantic-web.at/ 9

Publish Data!

Organize it!

License it!

Use Standard Open Formats

Add a Web API!

Integrate with the Web

Identify things!

Link them together!

Use RDF to publish data & model!

Raw Data now!

Linked Data Design Issues

1. Use URIs as names for things

2. Use HTTP URIs so that people

can look up those names.

3. When someone looks up a

URI, provide useful

information, using the

standards (RDF, SPARQL)

4. Include links to other URIs so

that they can discover more

things.
