Medline
MEDLINE is a bibliographic database produced by the U.S. National Library of Medicine (NLM). The database covers worldwide biomedical literature, the citations of which appear in Index Medicus, Index to Dental Literature and International Nursing Index. Over 99% of MEDLINE's citations are references to journal articles.
The MEDLINE Doctype handles the basic ASCII Interchange format of these databases.
The is a "master" document class. It handles the specialities of loads of medline as well as medline type formats such as those used by FilmNet and DVB mediagraphic interchange documents.
Record boundaries, field continuation etc are all handled. On BSn Isearch platforms the date of the document is also stored.
The MIME type for Raw is "Application/X-Medline"
LA is the only "reserved" tag name. All Medline children are free to use any tags they want BUT LA *must* be used for document language!
``Medline-type'' Records:
<Ftok><tok><tok>[<tok>]<sep>...
|_____________ Value of field
(starts at first non-space character)
Tags are left aligned and can be 2, 3 or 4 characters long!
Fields are continued when the line has no tag. A single space is sufficient in this implementation to guarantee a continuation.
The <sep> (' ' or '-') character is MANDATORY! This <sep> is in position 5 in versions 1.5 and earlier. In versions > 1.5 of Medline the third token is optional, so the <sep> can be in the 4th position as well. This allows line such as:
TI Fundamentals of Three-Dimensional Computer Graphicsto be accepted.
The record boundary seperator is either a blank line or a line where the first character is not a letter. This means that \014 (NP), a number or even - (dash) can be used as boundary seperators.
The table below show the default tag mappings, representing a cross-section of most Medline currently in use:
