18. So:
a lot of information is available about these
WW2 underground newspapers
(and the related persons & places) …
... but the chunks of data are (largely)
unconnected!
22. The Wikiproject Verzetskranten
will change this!
Systematically and uniformly describe & interlink all
1.300 Dutch underground newspapers from WW2
on Wikipedia
tinyurl.com/verzetskranten
Automatically makes data
available for open reuse projects
Wikidata -- DBpedia -- Dataviz
25. Global approach
1. Make central LOD-database
2. Build article template
3. Generate WP-article stubs -- using 1. and 2.
4. Involve WP-community to expand stubs into full
WP-articles
5. Make dataset available for open reuse
Wikidata -- DBpedia -- Dataviz -- et al.
First time data about undergound
newspapers is systematically
collected and linked online!
26. LOD-database for underground newspapers

34. So we have a LOD-database with data about
1.300 underground newspapers
Using an article template we can generate
1.300 uniform and interlinked WP-stubs
