Agenda
• CKAN – introduction
• User Groups and Features
• Testing and customization for the
  Decentralized Administration of Crete
  •   Screens from the testing enviroment
• Implementation Toolkit
• Added Value – Possible Synergies
About CKAN
• CKAN is a powerful data management system that makes
  data accessible – by providing tools to streamline
  publishing, sharing, finding and using data.
• Was developed by the non-profit Open Knowledge
  Foundation
• Aimed at data publishers (national and regional
  governments, companies and organizations)
• Used to power both official and community data portals,
  CKAN
• It now powers more than 40 data hubs around the world,
  including portals for local, national and international
  government, such as the UK’s data.gov.uk and the European
  Union’s publicdata.eu (beta version)
Ckan user groups
•Publishers
  • Local/national governments, data providers
•Open Data users
  • Researchers, journalists, programmers, NGOs,
     citizens
Features for publishers
• Publish data through a guided process or import
  via API/harvesting from other catalogs
• Customize: add your own metadata fields,
  themes and branding
• Store data within CKAN or on external (e.g.
  departmental) sites
• Manage: Full access control, version history with
  rollback, INSPIRE/RDF support, user analytics
Features for data users
• Explore: search, add, edit, describe, tag, group
datasets via web front-end or API
•Collaborate: user profiles, dashboard, social
network integration, comments
•Use: metadata and data APIs, data previews and
visualizations
•Extend: full documentation for building extensions

  • 8. ‘look and feel’ Customization
  • 9. Integration with existing information systems or Content management systems • extensions for full Drupal and Wordpress integration • API that makes it straightforward to add support for other CMSs and third-party catalogs
  • 10. Community functionality • Comments extension – users can add comments and discussion on a dataset. The extension can be enabled or disabled at any time. • Share – users can quickly and easily promote and discuss a dataset using twitter and facebook integration. • RSS/Atom feeds – create feeds of any changes and revisions to datasets and groups. • Follow extension – ‘follow’ a dataset to be informed of any changes, updates or new activity. • To do extension – flag a dataset with an issue or instructions of what is missing or still ‘to do’. This allows for a community driven effort for improving and adding to metadata.
  • 11. Testing for the decentralized Administration of Crete • Set up at Decentralized Administration of Crete for testing and customization • Customize layout, look and feel • Publish test data sets to explore functionality • Testing community features • Testing Interoperability features, apis etc
  • 12.

  • 17. Multiple types of resources for each data set (eg API)
  • 19. Federation • the data can be pulled regularly into CKAN from the existing repositories. • customizable “harvesting” mechanism which can fetch and import records from many different repository sources, including  Geospatial Servers  Existing web catalogues  Simple HTML index pages  Other CKAN instances This functionality is used on data.gov.uk to implement a Discovery Metadata Service used to fulfill the UK’s obligations under the EU INSPIRE directive. It is also used on publicdata.eu to pull in information from other catalogues to make them all searchable in one place.
  • 20. Federation • The harvesting functionality can be used to pull in metadata from other CKAN instances, it can also be used to create a federated network of CKAN nodes which share data between each other. CKAN follows the DCAT standard for data catalogue metadata, so data can also be federated from other non-CKAN catalogues.
  • 21. Ιmplementation Toolkit • 10 pg document • Guidelines for opening up data, focusing to to existing tools (CKAN) • Ckan installation • legal issues and licensing o greek and eu legislation and directives o Feedback from HOMER PROJECT • Cataloging data sets and Publishing data sets • Connecting with stakeholders, Building communities • Reusable for Homer Partner
  • 22. Participation to an open source project • A chance to actively participate for an Open source project • GFOSS is willing to coordinate resources for further development • Eg python developers, web designers
  • 23. Final Thoughts.. • GFOSS cooperates with OKFN and Informatics Directorate-General (DIGIT) • ADMS, Egov core vocabularies developed by ISA Group or EUROVOC • .. ADMS can be used for representing reusable semantic assets, e.g. schemas, ontologies, models, codelists...., hosted in metadata repositories. ADMS can act as a common layer among repositories that want to exchange data (see als http://joinup.ec.europa.eu/asset/adms/descriptio n)
  • 24. Final Thoughts.. • Utilize the whole experience for European level projects • Synergies (eg athens greek hackathons) • Transparency project in Greece
