  8. 8. More data? • Subconcept relations Minsk article links to "Poland before 1795" calling it "Polish-Lithuanian Commonwealth". "Polish-Lithuanian Commonwealth" is a subsection of "Poland before 1795" in the main article "Poland". • So is "Demography"… first level of subsections seem to work better as subconcepts, but not very reliable.

  16. 16. What can we do with the data? • JudaicaLink is an alternative source for authority data: Persons, Locations, Subjects. • We are in contact with potential linking partners: – Europeana, – the German National Library and – the National Library of Israel. • The German National Library started to include data from third-parties (like JudaicaLink) into the GND. • Most promising for a successful "match&merge": Persons.

  17. 17. What else, what's next? • We are looking for funding! • Generate links from scholarly content to JudaicaLink (Grant proposal submitted together with JSTOR). • Generate links with other data resources and between the encyclopediae (ongoing research). • And of course: find more encyclopediae or similar content to generate Linked Data from.
