Minimum Data Criteria
As part of the technical evaluation phase of the PMC evaluation and setup process, the publisher submits a representative set of sample files, which are evaluated to ensure that the journal's data meets PMC's technical quality standards. If a sample file submission fails to meet these minimum requirements, a journal's application to PMC will be rejected.
- Each sample package must be complete: all required data files (XML, PDF if available, image files, supplementary data files) for every article in the package must be present and named correctly.
- XML and PDF base file names must match exactly.
- Data file names must exactly match the names that are called out in the XML in name and case.
- All XML files must conform to an acceptable journal article DTD. If you plan on submitting articles in a format other than the JATS or NLM Journal Publishing DTD, please contact PMC at email@example.com prior to submitting any files.
- All XML files must parse according to their DTD. PMC validates data using the PUBLIC ID in the DOCTYPE declaration in each source file.
If you are using the NISO JATS Journal Publishing Tag Set, PMC strongly suggests that you tag your articles so that they conform to PMC Style. You can use the Online PMC Style Checker or download a version of the Style Checker that can be run locally to confirm that any JATS XML file conforms to PMC Style.
- Regardless of the XML DTD used, the following metadata information must be present and tagged with correct values in every sample file:
- Journal ISSN or other unique Journal ID
- Journal Publisher
- Copyright statement (if applicable)
- License statement (if applicable)
- Issue number (if applicable)
- Pagination/article sequence number
- Issue-based or Article-based publication dates
Articles submitted to PMC must contain publication dates that accurately reflect the journal's publication model, following these general guidelines for publication date tagging.
- All image files for figures must be legible, and submitted in high-resolution TIFF or EPS format, according to the Figure Graphic Formatting Guidelines.<
