Whilst the emphasis of the project was focused on the needs of the Research and Technologies Development (RTD) communities, it also had a broader perspective of serving the information requirements of industry and public sector in general.</p> <p>The DIFFUSE service was used to demonstrate many of the latest techniques in web site management. For example, it conformed to the guidelines issued by the Web Accessibility Initiative, it recorded Dublin Core metadata in all its files, it includes P3P-compliant privacy statements and it demonstrated the role of ISO/IEC 13250 Topic Maps in data navigation.</p> <p>The DIFFUSE Project's output is now being repurposed and updated by the Digital Curation Centre as the DCC DIFFUSE Standards Registry.</p> </div> <div class="internal"> <h4><a name="164" id="164"></a>DCC DIFFUSE Standards Registry</h4> <p>The DCC DIFFUSE Standards Registry aims to provide a single point of access to a range of standards and specifications related to the curation and preservation of access to digital material.
