PublicData.eu is striving to become the Pan European one-stop-shop, providing access to open, freely reusable datasets from numerous local, regional and national public bodies across Europe. After the first release of the PublicData.eu website (Alpha release was Jan 2011 & Beta release was June 2011) and it's subsequent upgrades (a significant upgrade was efected March 2012), OKFN worked towards the deployment of various personalization features, meant to improve the user experience on Publicdata.eu and spur more interest and interaction around the official data-sets.

Communities + Tools

7. What does open mean?
A piece of content or data is open if anyone is free to use,
reuse, and redistribute it — subject only, at most, to the
requirement to attribute and share-alike.

9. The LOD2 project
Citizen Use Case:
Make linked open data useful for the general public

10. A world-wide index of data
portals: datacatalogs.org

12. CKAN
leading open source data portal software
ckan.org

13. Serves two main markets
1. search and discoverability for end users and re-
users of data
2. data management tools for publishers

14. Search and discovery
Provides an online home for data
Browsing
Keyword search
Faceting by tags, formats, topics, countries and any
metadata field
Standardized interface for viewing

15. (Demo)

16. Data Management for Publishers
Easily store and update metadata records
Workflow and approval
Fine grained authorization controls
Broken link reports
Download and view counts

18. Add and edit dataset metadata through a simple user interface,
allowing you to:
- add further resources/files
- group and tag your dataset, making it easier to find through
browsing
- add maintainer, source and contact details
- create custom additional fields

19. Authorisation & access control

20. Workflow and approval

using Latitude and Longitude or GeoJSON

24. Geo-search -
filter by location
CKAN supports:
WMS previews
INSPIRE
GeoJSON

25. Harvesting and normalization
Get metadata from external catalogs and endpoints
CKAN will parse, validate and normalise to create
metadata records that look the same to end users no
matter where they came from
We can currently harvest: other CKAN catalogs,
CSW endpoints and WAFs serving ISO 19139
documents

28. Federation
Search across catalogs in aggregator sites (such as
publicdata.eu)
Data Catalog Interoperability Protocol: http://spec.
datacatalogs.org/

29. Multilingualism
Translated by the community into over 18 languages
Fully supports all international characters
Added multilingual search, setting dataset language
level, string translations using a vocabulary & more
for the European Commission Open Data Portal
