As per the DTD and tagging
specifications , the <classification> tag can be used to store
metadata and classifications for an article.
The idea is that it can be
used both for ad hoc classifications needed by BMC, and also for incorporating
external standard classifications (such as MESH) into the XML data.
List of types of classifications currently in
use, and examples of how they are used
(1)
Type: BMC
Sub Type: man_usr_id
Description: usr_id of
the BMC user responsible for submitting an article or report
Usage: Used by paper report/web report submission system
Example:
<classifications>
<classification
type="BMC" subtype="man_usr_id" id="23343332322"
/>
</classifications>
(2)
Type: BMC
Sub Type: man_spc_id
Description: spc_id of a
BMC specialty which this article falls under - - if multiple, then use multiple
classification tags
Note that the text names of
the specialties are included, mainly in order that fulltext searching will find
these words… They are not actually needed for the classification to be
correctly flagged in the database, so are in a sense optional.
Usage: Used by paper report/web report submission system
Example:
<classifications>
<classification
type="BMC" subtype="man_spc_id" id="30020001">Immunoarthritis</classification>
<classification
type="BMC" subtype="man_spc_id" id="30020007">Molecular
biology of arthritis</classification>
<classification
type="BMC" subtype="man_spc_id" id="30020011">Cell
signaling</classification>
</classifications>
(3)
Type: BMC
Sub Type: readership
Description: classification of whether an item has a specific or
a general readership
Usage: Used by paper report/web report submission system
Example:
<classifications>
<classification
type="BMC" subtype="readership"
>General</classification>
</classifications>
(4)
Type: BMC
Sub Type: old_arx_id
Description: the old arx_id or <ui> of an article where this has been changed
Usage: Used for locating an articles backup file, or wherever it might be important to know the previous id number.
Example:
<classifications>
<classification
type="BMC" subtype="old_arx_id"
>ar-2-5-361</classification>
</classifications>
(5)
Type: BMC
Sub Type: user_supplied_xml
Description: Indicates that some or all of the XML was provided by the Authors submitted files. The 'id' will indicate what format the data was supplied in - eg: 'endnote' means references were extracted from Endnote format 'refman' means references were extracted from Refman format.
Usage: Used by XML-markup companies to know not to mark-up certain sections into XML, and during corrections for identifying where mistakes in conversion have been made.
Example:
<classifications>
<classification
type="BMC" subtype="user_supplied_xml" id="endnote"
/>
</classifications>
Recommendations
for rendering the contents of the classification tag
By default, the renderer
should not output any of the content of the <classification> tag
directly, but it may choose to alter its output in certain ways based on the
content of those classifications.
