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!
