NLM Releases Production MeSH RDF

The National Library of Medicine (NLM) is pleased to announce the move of MeSH (Medical Subject Headings) RDF from a beta version to production around September 8, 2017. The initial beta release of MeSH RDF was published in November 2014 for selected institutions and organizations. Subsequent releases of the beta version occurred in June 2015, November 2015, and November 2016.

Release notes are available at http://hhs.github.io/meshrdf/release-notes.html.
