CKAN is the world’s leading open-source data portal platform.
CKAN is a complete out-of-the-box software solution that makes data accessible and usable – by providing tools to streamline publishing, sharing, finding and using data (including storage of data and provision of robust data APIs). CKAN is aimed at data publishers (national and regional governments, companies and organizations) wanting to make their data open and available.
CKAN is used by governments and user groups worldwide and powers a variety of official and community data portals including portals for local, national and international government, such as the UK’s data.gov.uk and the European Union’s publicdata.eu, the Braziliandados.gov.br, Dutch and Netherland government portals, as well as city and municipal sites in the US, UK, Argentina, Finland and elsewhere.
Publish and Manage Data
An intuitive web interface allows dataset publishers and curators to easily register, update and refine datasets in a distributed authorisation model called ‘Organizations’. ‘Organizations’ allow each publisher to have their own dataset entry and approval process with numerous members. This means responsibility can be distributed and authorization access managed by each department or agencies’ admins instead of centrally.
You can add and edit data in CKAN in many ways, including:
- Directly via the web interface
- Using CKAN’s rich JSON API
- Via custom spreadsheet importers
Many organisations already have their data in repositories with well-defined process and procedures for publishing and managing data. In this case the data can be simply pulled regularly into CKAN from the existing repositories. To facilitate this model we’ve developed a sophisticated and customisable “harvesting” mechanism which can fetch and import records from many different repository sources, including:
- Geospatial CSW Servers (see geospatial for more information)
- Existing web catalogues
- Simple HTML index pages or Web Accessible Folders
- ArcGIS, Geoportal Servers and Z39.50 databases
- Other CKAN instances
This functionality is used on data.gov to get data in from hundreds of their agencies, 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. – See more at: http://ckan.org/features/#sthash.VIaQ52aI.dpuf
- Publisher (Organization) admin dashboard: manage members, datasets, approve datasets to be public, manage harvest sources all from each organization admin page.
- Forms: Create portal or publisher specific forms that pre-fill certain fields or have additional required fields to fit individual requirements.
Datasets can be public or private. If they are private they are only visible to the logged in members of their owning publishing Organization (e.g. Department of National Statistics). Admins can approve datasets for publication with our bulk editing tool which lets you search, facets and pick datasets to become public or private.
