Thank you Alexandru,
So please allow me one more question:
I see the use of dbpprop:longDeg, dbpprop:lonDeg, dbpprop:longD, ....and
certainly more typos
So I understand that this is coming from what you say "people not respecting
the correct formatting in wikipedia ", si that right ?
As it would be useful to know all the typos, is there a place to see all of
those properties ?
I tried to look for them in the ontologies files available here [1], but with
no success
I bet that SPARQLing the end-point and doing string match to properties
starting with "dbpprop:lon" is maybe my best chance ?
Thank you
Fabian

Hi Fabian,
The dbpprop properties come directly from the infoboxes and are 1:1
extractions. The geo properties are the results of the infobox mappings to the
geo ontology. In many cases the mappings don't work right due to people not
respecting the correct formatting in wikipedia or the mappings not being
created yet, that's why we keep the dbpprop properties too.
So, to answer your question, use the geo: properties for geo coordinates. Use
the dbpprop properties if a resource doesn't have geo properties, this means
that the mappings haven't been made for that infobox yet. In this case you
"could" also create the corresponding mappings.
Hope this helps.
Cheers,
Alexandru

Hi,
It seems different properties are used for geo data, as already pointed out in
2009 [1]
dbpprop:latDeg, latMin, latSec etc.
geo:lat, geo:long
dbpprop:latLong
Is there any documentation about those properties, and when to expect which one
?
When SPARQLing about a resource to find out if that resource does have a
geolocation or not, should all properties be queried (OPTIONAL), and if one of
them is found we can assume it is the one to use - no need to check about the
other ones ?
Thank you for any information
Fabian
