Comprehensive Knowledge Archive Network (CKAN)

Depiction of Comprehensive Knowledge Archive Network (CKAN)

CKAN is a registry or catalogue system for datasets or other "knowledge" resources. CKAN aims to make it easy to find, share and reuse open content and data, especially in ways that are machine automatable.

Those familiar with software services like freshmeat, CPAN, or apt can think of CKAN as providing an analogous service for content and data.

The CKAN software is used to run the CKAN service: http://www.ckan.net/ and is also running the catalogue behind http://data.gov.uk/ as well as more than 15 other sites around the world including in Germany http://offenedaten.de/, Canada http://datadotgc.ca, and France http://fr.ckan.net.

Andreas Blumauer (Semantic Web Company, CEO)

15 years ago we all were excited when we published HTML for the first time and it didn't take a long time until all of us were "on the internet". Now we are starting to publish data on the web. Based on semantic web technologies professional data management will be possible in distribut… read

Dr. Jens Lehmann (Universität Leipzig, Research Group Leader)

The size and number of Semantic Web knowledge bases published as Linked Open Data has been growing tremendously over the past years. The LOD2 project will be a key factor for sustaining this momentum. More importantly, the quality of knowledge bases and the scalability of methods access… read

Dr. Sören Auer (Universität Leipzig, LOD2 coordinator)

The Linked Data paradigm is a simple and efficient way for integration of heterogeneous information on the Web. Ultimately, we will, for example, be able to search for a new appartment and a close-by available spot in child care in one go.

Dr. Giovanni Tummarello (Digital Enterprise Research Institute, Research Unit Leader)

Semantic Markups on the Web could drive information reuse to enable scenarios and applications which we can now only dream of. The idea is extraordinarely compelling, but we know now it won't simply realize itself. The LOD2 project is now a great opportunity for inspired and coordinated… read

Dr. Peter Boncz (Centrum Wiskunde & Informatica)

The publishing of ever more datasets by e.g. governments adds value for many key applications including business intelligence, which will drive the Linked Open Data (LOD) paradigm going forward. In the LOD2 project, CWI is working to increase the scalability and performance of querying … read

Christian Dirschl (Wolters Kluwer, Content Architect)

Linked (Open) Data will change the existing publishing paradigms! Creating high quality content for professional usage will remain an important factor in future publishing, but additional access points and new usage environments will equally define its success.
