The network for innovation in European public sector information

Share-PSI in a Nutshell

The Share-PSI network brought together government departments responsible for implementing the (Revised) PSI Directive across Europe along with standards bodies, academic institutions, commercial organisations, trade associations and interest groups. A series of workshops in 2014 and 2015 identified what does and doesn't work, what is and isn't practical, what can and can't be expected of different stakeholders. The primary output is a set of Best Practices that can help the public sector share its information most effectively and efficiently. Each Best Practice is based on experience in multiple contexts, and backed up by ample reference material. This work is closely allied to the W3C’s more technical Data on the Web Best Practices.

But Best Practices only get you so far.

In order to be able to follow them you need to bear in mind the local context: the technical, legal and organisational infrastructure in which PSI is generated. To meet this need, many organisations create their own guidelines, handbooks or knowledge banks. Share-PSI has curated a set of 40 such localised guides that cover 24 countries plus a number of cross-border guides tailored to specific domains of interest. They vary in style and target audience but they all offer advice that is consistent with some or all of the Share-PSI and W3C BPs and, in many cases, cite them directly.

In this way, the project offers a route to local guidance based on international Best Practice, increasing the value of Public Sector Information by making it more interoperable, more discoverable and more readily used by others.

Short version

Share-PSI offers a range of high level Best Practices for implementing the (Revised) PSI Directive that complement the W3C’s more technical Data on the Web Best Practices. A set of localised guides, available in a variety of languages, make those Best Practices actionable in different contexts, be it in a given country, region or cross-border domain of interest.
