<!-- NLM MedlineCitationSet DTD
This is the DTD which NLM has written for Internal and External Use.
January 1, 2010
**THIS IS THE FORTHCOMING DTD TO BE USED FOR MEDLINE/PUBMED DATA IN
2010 AND IS NOT CURRENTLY IN USE.
SEE http://www.nlm.nih.gov/databases/dtd/ FOR LINKS TO THE SUITE OF
DTDS DATED JANUARY 1, 2009 CURRENTLY IN USE.**
NOTE: The use of "Medline" in a DTD or element name does not mean the record
represents a citation from a Medline-selected journal. When the NLM DTDs and
XML elements were first created, MEDLINE records were the only data exported.
Now NLM exports citations other than MEDLINE records using these tools. To
minimize unnecessary disruption to users of the data and tools, NLM has
retained the original DTD and element names (e.g., NLMMedlineCitationSet,
MedlineTA, MedlineJournalInfo)).
NOTE: StartPage and EndPage in Pagination element and NameID in Author
and Investigator elements are not currently used; are reserved for future use.
* = 0 or more occurrences (optional element, repeatable)
? = 0 or 1 occurrences (optional element, at most 1)
+ = 1 or more occurrences (required element, repeatable)
| = choice, one or the other but not both
no symbol = required element
-->
<!-- ================================================================= -->
<!-- Revision Notes Section
The following changes were made:
a. The nlmmedline_090101.dtd and nlmmedlinecitation_090101.dtd have
been used as the base.
b. The nlmcommon and sharedcatcat external entities have been merged into
this single DTD. All extraneous nlmcommon and sharedcatcit objects not
required by MedlineCitationSet have been removed.
c. No internal DTD entity references are used.
All elements and attributes are defined explicitly in this DTD.
d. All unused and unmapped tags have been removed.
e. Removed Book subtree from Article.
f. Removed HSR, HMD and SIS from KeywordList Owner.
g. Removed SIS from MedlineCitation Owner.
h. Removed SIS and NOTNLM from GeneralNote Owner.
i. Removed IM,QCICL,QCIM and SGC from Source.
j. Removed Hour, Minute, and Second.
k. Removed DatesAssociatedWithName,NameQualifier,OtherInformation and
TitleAssociatedWithName from Author and PersonalNameSubject.
l. Removed PublicationInfo and its related elements.
m. Removed NCBIArticle.
n. Removed NlmDcmsID from MedlineCitation.
o. Removed Prefix attribute from OtherID.
p. Removed BroadJournalHeadingList,BroadJournalHeading,Coden,
CollectiveTitle,Coverage,FirstName,Frequency and MiddleName.
q. Reorganized CommentsCorrections to one main element with
RefType attribute. RefType valid values were previously
element names under CommentsCorrections. Added Cites as new
RefType valid value.
r. Added NameID to Author and Investigator elements.
