Imagine the distant future where a researcher wants to gain access to an ancient digital publication about a research that has been conducted in 2009 on gene technology that made crops resistant to pesticides.A Persistent Identifier found in a more recent publication takes the researcher to the old document. Luckily the ancestors found a way to implement a strategy and a policy that made access to their documents possible, especially now that the old http-based internet is gone.This workshop is an interactive event where stuctured discussions take place on how to create a sustainable organisational model and a robust policy in order to build a trusted and reliable information infrastructure. This information infrastructure is able to locate and redirect someone/something to a knowledge asset that is part of our human heritage.The Knowledge Exchange Persistent Identifier Workgroup is working on a URN:NBN based pilot to demonstrate global resolution with Long Term Strategies. There are many other Persistent Identifier technologies, however in this pilot the Policy & Strategy part has the major focus.The answers and discussions in the workshop will contribute to this focal point.ELPUB agenda KE-PIDThe agenda for the workshop is divided in two parts:1. introduction (to provide context)2. interactive (to provide answers in dialogue)The goal of the workshop is to share ideas about user requirements and have input in the KE-PID project, which aims to setup a Global Harmonisation Resolution service and most importantly a sustainable organisation.We would like to stress out that this is not a technical workshop, but organizational issues will be tackled.Agenda:1 Introduction* opening and explanation of today's mission* explanation about Persistent Identifiers* examples / demo of Persistent Identifiers2 Dialogue / sharing experiences* session in groups of 4 persons: find out the user requirements and expectations of PID's* reporting back to plenary session* plenary prioritisation (finding out the risks and issues to be solved)* back in groups: find out who could do what, on a national and local scale: roles and responsibilities* plenary session: present of outcomes
