id="Public_Domain_Status_of_Creative_Works_on_a_Community_Wiki">Public Domain Status of Creative Works on a Community Wiki</span></h2> <p>The PDWiki project's goal is to build a community around publicly editing listings of copyright status of creative works. It has grown, changed, and gone through many phases to get to where its at now. It currently has <a href="#Components">three solid components</a> (Open Library integration, PDregistry.ca, and mediawiki plugin integration) to its strategy, and has played key roles in both the <a href="/wiki/CCZero" class="mw-redirect" title="CCZero">CCZero</a> and <a href="/wiki/Content_Registries" title="Content Registries">Content Registries</a> projects.</p> <p>Not invented here: As the development process of the components seems to have slowed down, we would like to mention, that in the meanwhile several <a href="/wiki/Content_Registries" title="Content Registries">Content Registries</a> are offering registration of public domain works. At the 2nd COMMUNIA conference in Turino the team of <a rel="nofollow" class="external text" href="http://RegisteredCommons.org">RegisteredCommons</a> had presented an API and <a rel="nofollow" class="external text" href="http://www.slideshare.net/rasos/semantic-copyright-expression-options">proposed a metadata scheme</a>, allowing to express CC, PD and full copyright.</p> <h2><span
