Linked Open Data Hackfest

Linked Data is a way of formulating data so that it forms a global distributed database. Huge amounts of data are already available, but not too much from Norway. We set out to fix this.

What?

A workshop on Linked Open Data, organized by the Department of Informatics in collaboration with Ministry of Government Administration, Reform and Church Affairs. We will bring in some of the best people in the field to help with working with data.

Programme

• Introduction to Linked Open Data, 15 minutes, by Kjetil Kjernsmo
• Available data for doing interesting things, 15 minutes, David Norheim
• Introduction to working with LOD with Java, 15 minutes, David Norheim
• Introduction to working with LOD with Perl, 15 minutes, Kjetil Kjernsmo

Then we discuss what to hack and go on doing it!

Available data

• Dataveveren Oris http://sws.ifi.uio.no/oris, med endepunkt http://sws.ifi.uio.no/oris
• Computas' LOD server http://opendata.computas.no:7001/joseki/
• Norske postnummer med koordinater http://www.erikbolstad.no/geo/noreg/postnummer/
• http://beta.data.norge.no/
• http://no.ckan.net/
• http://yr.no/
• http://api.met.no/
• SKOS Linked Data av Startsidens kategorier

Suggested projects

• Link Norwegian fylker to First-order-administrative division in geonames.org.
• Link Norwegian kommuner to Second-order-administrative division in geonames.org.
• Link postnummer to Norwegian kommuner. NB! One postnummer might be in more than one kommune -- although the table from Posten doesn't say so (but the text on the download-page does ... [1] )
• Link important places to Norwegian kommuner and geonames.org.

Tools

Just in case someone wants to read up, these are some examples of tools we may want to discuss:

• Perl-modules: RDF::Trine, RDF::Query, Web::Scraper and RDF::LinkedData.
• The Java-framework Jena
• Google Refine to link and fix dirty data.
• RDFquery JavaScript library.
