Agreed, ISCED 1997 classifications are technical debt that we need to
work towards eliminating, not a parallel standard that we would want to
maintain in perpetuity or even increase usage of.
The current wiki documentation is inconsistent, giving a "general
description" of ISCED 1997 but using a mix of 1997 and 2011 definitions
for each country. The page should expliictly say that any new
isced:level=* usage should conform to the 2011 standard. Otherwise, some
mappers might gravitate toward the 1997 standard for ostensible
consistency with nearby schools, while others would gravitate toward the
2011 standard because it's newer and better defined.
A MapRoulette challenge would be great for reviewing existing usage. You
could choose a cutoff date after which ISCED 1997 classifications were
unlikely to be entered anymore. This would be easier on a
country-by-country level, where local mappers understand the local
educational system well enough to know what might need to be reclassified.
To avoid repeating this mess in the future when a fourth version of
ISCED comes out, it does make sense to explicitly state the standard
being used. But instead of isced:level:1997=* and isced:level:2011=*,
how about combining isced:level=* with isced:version=1997/2011, for
consistency with public_transport:version=* and population:date=*?
