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.
