[Dbpedia-developers] Loading mappings, exception

Uros Milosevic Wed, 20 Nov 2013 08:07:24 -0800

Hi all,

Sorry for the not so descriptive message subject. I can successfully run
the extraction framework with only the label extractor on. If I add the
mapping extractor and throw in a sample mapping for Serbian (single
infobox template), the framework crashes. More info below:

And here's my Mapping_sr.xml:

I'd be very grateful for any assistance!
