Hello all,
I stumpled across some inconsistencies regarding the extraction of GND
identifiers. As you probably know, GND is a widely used authority
database in German-speaking Europe, containing information about
millions of entities [1]. It would be great if we could sparqle for GND
IDs in dbpedia in order to match other GND-tagged data with dbpedia
entities.
for instance check out:
http://de.dbpedia.org/page/Apnoetauchen
there seem to be two GND entries in this record:
dbpedia-owl:individualisedGnd = 4649698-1
(this property was once derived from the discontinued PND authority
database)
and
prop-de:gnd = 4649698 (xsd:integer)
(another GND-lookalike property but with the "-1" cut off, due to
casting it as integer I guess.)
here is another record:
http://dbpedia.org/page/Johann_Wolfgang_von_Goethe
containing:
dbpprop:gnd = 118540238 (xsd:integer)
(third property, this time again as xsd:integer, but GND allows
non-numeric characters to be part of a GND ID, for instance a "-" or
"X". this example is correct but xsd:integer will fail on other ids
containing non-numeric characters)
I just wanted to point out these things for the moment. It would be
great if we could harmonize them sooner or later.
Best,
Leander
