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

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.
