The National Library of Medicine is pleased to announce that a second beta release of MeSH(r) (Medical Subject Headings) RDF was published on June 18, 2015 and is available at http://id.nlm.nih.gov/mesh/. The first beta release of MeSH RDF was published in November 2014 for selected institutions and organizations. Since that time, NLM Linked Data Infrastructure Working Group has been working with the selected institutions to test and evaluate MeSH RDF. Feedback from these and other interested parties have provided NLM with data on the potential use cases for MeSH RDF. This second beta release of MeSH RDF is designed to address some of our users' needs and to improve the product. This second beta phase is now open to any interested parties and NLM is encouraging any potential users of MeSH RDF to test this new beta version and provide comments and feedback. Please see the full announcement at http://www.nlm.nih.gov/news/mesh_rdf_beta_2015.html and the release notes at http://hhs.github.io/meshrdf/release-notes.html for further information. __________________________________________________ Barbara Bushman Assistant Head Cataloging and Metadata Management Section National Library of Medicine 8600 Rockville Pike Building 38, Room 1N13 Bethesda, MD 20894 301-496-7135 301-402-1211 (fax) [log in to unmask]<mailto:[log in to unmask]>
