NOSAD Wikibase POC
- Presentatörerna som Oswald ID, Sträng, WD - snyggt mönster GITHUB kommentar där alla presentatörer får en persistemt identifierare dvs. FAIRDATA F1
- SPARQL Federation med Wikidata
- Presentatörer som finns på Dataportalen
- Bolag på Oswald med organisationsnummer och koppling alla bolag / samma men med länk handlingar.se för organisationen
Misc
- POC koppla Wikidata till Nosad Dataportalen Scholia med Linked data....
- Skapa entity schema #18
= Frågor
Lista föreläsningar i omvänd tidsordning med ID, titel, videolänk osv.
The following query uses these:
