PMCPMC is a free archive of biomedical and life sciences journal literature at the U.S. National Institutes of Health's National Library of Medicine (NIH/NLM). It is a repository for journal literature deposited by participating publishers, as well as for author manuscripts that have been submitted in compliance with the NIH Public Access Policy and similar policies of other research funding agencies.
Add a Journal to PMCParticipation in PMC is open to any English-language life sciences journal that meets NLM's standards for the archive.
A journal must qualify on two levels, both the Scientific quality of the publication, and the Technical quality of its digital files.
A journal must provide PMC with the full text of articles in an XML (eXtensible Markup Language) format that conforms to an acceptable journal article DTD (Document Type Definition). PMC does not accept articles in HTML format.
NLM recommends that data be submitted in XML conforming to the NISO JATS Journal Publishing Tag Set, but PMC will also accept data in other full-text article DTDs that are widely used in life sciences journal publishing.
Files required for each deposited article:
- A separate XML data file for the full text of each article.
- The original high-resolution digital image files for all figures in each article.
- A PDF, if one exists, in addition to the XML version (but not as the only form.)
- Supplementary data files (e.g., spreadsheets or video files) available with the article.
JATS is an application of NISO Z39.96-2015, which defines a set of XML elements and attributes for tagging journal articles and describes three article models.
The content on this site is the supporting documentation for the standard. JATS is a continuation of the NLM Archiving and Interchange DTD work begun in 2002 by NCBI.https://jats.nlm.nih.gov/index.html
