Share-PSI is the pan European network offering advice on implementation of the (Revised) PSI Directive, formally the European Directive on the Public Sector Information. It comprises many of the 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. Advice is offered as a set of Best Practices. Each of these is a stand alone document that is based on one or more case studies presented during the workshop series. Best Practices are supported by evidence of their implementation, details of which are provided in one or more guidance documents that are produced by EU Member States.
