Main Points

1. Linked (Open) Data is coming of age

2. Linked data technology is already making it into Drupal modules

3. EU funds many projects to simplify publishing, consumption of linked data

4. Drupal has mass, will it contribute linked data mass?

5. Public bodies are publishing linked data: will it be with Drupal?

Digital Agenda for Europe

Public authorities produce large amounts of data that could become the raw material for new, innovative cross-border applications and services e Examples of products and services based on the re-use of public sector information (PSI) are GPS, weather forecasts, financial and insurance services.PSI is the single largest source of information in Europe. Its estimated market value is €27 billion. Re-used, this public data could generate new businesses and jobs and give consumers more choice and more value for money.

27

Digital Agenda for Europe

Networking across Europe and in a wider international context (with Member States, PSI Alliance, national industrial associations, PSI platform, software developers and open data communities) to further stimulate action and monitor progress towards a stronger and more transparent environment for the growth

of European PSI.
