π’ HMC FAIR Friday Seminar
More than a decade after the FAIR Principles were introduced, a key question remains:
π What value has FAIR actually delivered to researchers?
In this talk, Sebastian Hellmann and Jan Forberg explore the microeconomics of FAIR adoption and present open-source tools #Databus and #MOSS from the #DBpedia Association ecosystem.

Surprisingly, I could not find an Issue about this #DBpedia problem. Now there is one: https://github.com/dbpedia/extraction-framework/issues/820
Contrary to my initial guess of an extractor bug, further investigations made an SPARQL endpoint (#openlinksw #virtuoso) bug seem more likely.
Issue validity Could not check, due to DIEF ERROR 502 response. Error Description Many resources are missing some rdf:type statements. Pinpointing the source of the error It affects the SPARQL (htt...
Remarkably:
β‘οΈ Despite the lack of #DBpedia types, equivalent #Wikidata types are present in DBpedia.
β‘οΈ Not all resources are affected: e.g. https://dbpedia.org/page/John_Young_(astronaut) is typed as http://dbpedia.org/ontology/Astronaut.
β‘οΈ Right and wrong typed astronauts have the astronaut infobox (which is properly mapped https://mappings.dbpedia.org/index.php/Mapping_en:Infobox_astronaut) on #Wikipedia.
I guess an extractor bug πͺ².
Side effect: Many astronauts are displayed as "animals". Although on might consider this as ontologically correct, it is quiet odd.
With ABECTO 3.1.5, I restored regular pushes of space travel data deviations between #Wikidata and #DBpedia to https://mismatch-finder.toolforge.org @nightrose. But it provides (at first glance) strange results (π https://mismatch-finder.toolforge.org/results?ids=Q107667|Q115651852), like:
β‘οΈ John Young member of the crew of Apollo 16 mismatches http://dbpedia.org/resource/Apollo_16
β‘οΈ SpaceX Crew-10 crew member Anne McClain mismatches http://dbpedia.org/resource/Anne_McClain
Reason: Missing http://dbpedia.org/ontology/SpaceMission, http://dbpedia.org/ontology/Astronaut, β¦ type statements in @dbpedia.
An unconventional approach to avoid providing an email address in the User-Agent was chosen in #DBpedia by reusing the user agent of #curl: https://github.com/dbpedia/extraction-framework/commit/de3ca70694f347db84a2daeb88d8218506075f81
I proposed an alternative: https://github.com/dbpedia/extraction-framework/issues/819
A huge thank you to Denny VrandeΔiΔ
for kicking off #ISWC2025 with a great keynote: βWikipedia and the Semantic Webβ.
He highlighted how #SemanticWeb ideas shaped #SemanticMediaWiki, #DBpedia, and #Wikidata - now the worldβs most-edited wiki!
