<P>Member States should, within the framework provided for in this Directive, have flexibility in choosing the specific type of licensing mechanism, such as extended collective licensing or presumptions of representation, that they put in place for the use of out-of-commerce works or other subject matter by cultural heritage institutions, in accordance with their legal traditions, practices or circumstances. Member States should also have flexibility in determining what the requirements for collective management organisations to be sufficiently representative are, as long as that determination is based on a significant number of rightholders in the relevant type of works or other subject matter having given a mandate allowing the licensing of the relevant type of use. Member States should be free to establish specific rules applicable to cases in which more than one collective management organisation is representative for the relevant works or other subject matter, requiring for example joint licences or an agreement between the relevant organisations.</P>
