- It is impossible to link from Wikidata to
Wikipedia-Redirects that point to a sub-section of an
existing article.
Example: http://www.wikidata.org/wiki/Q736587
- The Peter and Paul Cathedral in Saint Petersburg (Russia)
does not have a separate entry on the German Wikipedia, but
a Redirect that points to the respective sub-section of the
article on the Peter and Paul Fortress in which the
cathedral is located. When I add the name of the Cathedral
redirect page into Wikidata, it automatically returns the
lemma of the Fortress and consequently produces an error, as
the Fortress is indeed another entity covered by the data
object http://www.wikidata.org/wiki/Q38646.
An example related to the Swiss monuments
lists: http://www.wikidata.org/wiki/Q222022
- Grimselsee. Here, the Wikidata object has been assigned
the property “Swiss cultural property of national
significance“, based on the respective category attributed to
the article. But this information is not correct: not the
lake (Grimselsee) is a cultural property of national
significance, but the Grimsel dam. If we were to produce the
monuments lists in Wikipedia based on this entry, we would
have “Grimselsee” (the lake) in the monuments list instead
of the Grimsel dam. – How can we resolve that issue? – By
generating separate Wikipedia articles for each entity in
Wikidata? (I’m not sure whether that’s practicable). Another
approach would consist in creating a sub-section in the
article on “Grimselsee” (the lake) that contains a few
sentences about the dam. Via a re-direct, we could directly
point to the sub-section about the dam; but this is not
supported by Wikidata. Furthermore, there might be a more
general issue related to the “fuzzy” categorizing used in
Wikipedia that is not really compatible with Wikidata (in
this case, the “Cultural Property of National
Significance”-category has been attributed to a lemma that
is no doubt related to the protected cultural property, but
which is not referring to the cultural property as such).
