18. Policy Implications 23 • Commitment and investment are necessary for successful implementation of the dissemination network • Better-informed and timely decision can be made through the use of this network • Main problem: setting up an environment for information sharing, i. e. , policy principles need to be set up • Other problems such as pricing of data, copyrights, security concerns need to be clarified
