[Utilities-announce] PubMed E-Utilities DTD Update 2025

[utilities-announce at ncbi.nlm.nih.gov]

Dear NCBI PubMed E-Utilities Users,

The PubMed DTD for 2025 will be updated in early December 2024.

The 2025 DTD is now available:
https://dtd.nlm.nih.gov/ncbi/pubmed/out/pubmed_250101.dtd

Additions/Changes since pubmed_240101.dtd:

  1.  Updated DescriptorName model to allow for optional AutoHM="Y" attribute
  2.  Updated QualifierName model to allow for optional AutoHM="Y" attribute

The attribute will be used to distinguish between Descriptors/Qualifiers that have been added by curators or MTIX based on information in the article text (attribute not present), and Descriptors/Qualifiers that have been added automatically after a supplementary concept record (SCR) was indexed (AutoHM="Y"). See https://www.nlm.nih.gov/mesh/intro_record_types.html for more information on MeSH record types.

Please see pubmed_250101.dtd Documentation<https://dtd.nlm.nih.gov/ncbi/pubmed/doc/out/250101/index.html> for annotations and examples for elements and attributes defined in the PubMed DTD.

Thank you,
PubMed Development Team
