KBART 4.2.6: embargo inconsistencies

kbart_logo_small.png

Core problem:


Knowledge base developers are often uncertain as to how to apply
varying embargo terms, as the same terms can be used by different content providers in
different ways.

User impact:


Embargo terminology is complex, particularly in instances of a “1-year
embargo”, which might mean the previous 12 months are not available, or that the
current (or previous) calendar year is not available (i.e., from January of a certain year to
the present). Users cannot know with certainty if the article they seek will be found in a
given database when the issue date falls in or near the range of the embargo period.

Solutions:


Consistent usage of the ISO 8601 duration syntax, which allows multiple
types of embargo to be described, can mitigate this problem. See Section 5.3.2.14 for
details.
