Hi Jean,
In general, there is no real standard way to fill in infobox values. It can
contain numbers, links and even other templates. This lack of regularity
makes parsing it a pain.
For example, in English, the field is filled like this:
|lat_deg = 50 |lat_min = 44 |lat_sec = 02.37
|lon_deg = 7 |lon_min = 5 |lon_sec = 59.33
While in German, it is like this:
|Breitengrad = 50/44/02.37/N
|Längengrad = 7/5/59.33/E
There seems to exist already a GeoCoordinates parser in the DEF, that gets
triggered when you use GeocoordinatesMapping instead of a PropertyMapping.
http://mappings.dbpedia.org/index.php/Template:GeocoordinatesMapping
You would probably have to extend the GeoCoordinateParser to include this
new way to express lat/log
http://dbpedia.hg.sourceforge.net/hgweb/dbpedia/extraction_framework/file/febe0119845a/core/src/main/scala/org/dbpedia/extraction/dataparser/GeoCoordinateParser.scala
Or you can try to convince Jona to extend it for you. :)
Cheers,
Pablo
