As you develop your Data Management and Sharing Plans, make sure you do not include hypertext (e.g., hyperlinks and URLs) in the DMS Plan attachment. Our hyperlink policy applies to DMS Plans as well, and NIH may withdraw your application from consideration if you include them. Don’t risk it!

For example, in the DMS Plan attachment you should include the name of the proposed data repository but do not provide the link or URL. For more format guidance and other details on what to include, see the Writing a Data Management & Sharing Plan page.
