Subject: [mapserver-users] Multilingual map files
Dear list members
I would like ask how map files for multilingual applications
are handled by mapserver users.
Multilingual information may impact the map in various ways.
As by now, those come to mind:
* Fix strings in the map file, (NAME, DESCRIPTION etc)
* Database borne data, changing column for different
languages as for LABELITEM
* Queries changing with language, so that DATA/FILTER
statements must be adapted to the current language (e.g.
WHERE lang_id='en').
What we are currently doing is to write the mapfiles like:
CLASS
NAME "IT:Progetti linee|DE:Projekte Linien"
SYMBOL 'circle'
SIZE 3
COLOR 0 0 255
END
METADATA
"DESCRIPTION" "IT:Progetti|DE:Projekte"
END
LABELITEM "IT:gemi|DE:gemd"
and modify the labels through Mapscript before rendering the
map. This works if the map file is processed by Mapscript,
whereas it would not work for CGI and W*S services. We would
need a map file for each language for those services.
For WxS, the specs themselves don't handle this, but it would be nice to
handle multilingual metadata in one document, i.e.:
<Name xml:lang="en-CA">road</Name>
<Name xml:lang="fr-CA">rue</Name>
I remember Arnulf Christel mentioning some work on multilingual WxS by
OGC. Do you know anything about this?
In our environment, we've created one mapfile / language. One thing you
could do is use MapScript WxS to intercept an incoming request (say with
an extended lang parameter), then, once you have the lang, set the
values in the mapfile accordingly.

Thanks,
Peter
How do you handle i18n in MapServer?
