Krötzsch/Vrandečić/Völkel (2006) Semantic MediaWiki. doi:10.1007/11926078_68
from 2006 on SMW is being used in > 1500 public installations
(and many more non-public)

Main developers: James Hong Kong, Jeroen De Dauw
2012 Wikidata project begins
with Markus Krötzsch, Denny Vrandečić, Lydia Pinscher, Jeroen DeDauw

FINA Wiki and Wikidata
FINA ID could be a qualifier in
Wikidata: Property:P7842
SMW can provide „result
formats“ RDF, JSON, CSV
Can be imported directly in
OpenRefine
SMW can re-import data via
DataTransfer extension
SMW can re-use vocabularies
(OWL, SKOS, FOAF…)
How to make futher use of
Wikidata (e. g. Vienna = Q1741)?
17. www.kdz.or.at
SMW and Wikidata usecases
Basic Wikidata lookup/mapping
lookup implemented via External_Data
basic linking with "External identifier"
assign SMW Property:Country to P17
[[equals Wikidata Property::P17]]
reuse of „Service links“?
Reconcile SMW data with Wikidata
possible already, via OpenRefine
should be doable inside SMW (extension using reconciliation API)
Push SMW data (semi-)automatically to Wikidata
possible by treating RDF, JSON, or CSV export like any other
datasource for Wikidata
should be doable inside SMW: on a per-entry-base or batch
