Today in the ISE 2025 lecture on OWL, the Web Ontology Language. Tired of using slide presentations (at temperatures like today and giving the same presentation all over again), I spontaneously decided to design arbitrary OWL ontologies together with the students on the good old blackboard ;-)

Ammar's PhD thesis can be found online at https://cris.maastrichtuniversity.nl/en/publications/enhancing-the-interoperability-and-reusability-of-nanosafety-data and his defense is live streamed, see the link at https://www.maastrichtuniversity.nl/events/phd-defence-ammar-ammar
It contains a lot of #openscience: https://social.edu.nl/@egonw/114766897696096032
And in the afternoon there is a minisymposium on the thesis topic: https://social.edu.nl/@egonw/114705860626722108
Tomorrow, we will dive deeper into ontologies with OWL, the Web Ontology Language. However, I'm doing OWL-lectures now for almost 20 years - and OWL as well as the lecture haven't changed much. So, I'm afraid I'm going to surprise/dissapoint the students tomorrow, when I will switch off the presentation and start improvising a random OWL ontology with them on the blackboard ;-)

In this blog post at https://s.gwdg.de/m5Bu3L I showcase the #NFDI4BIOIMAGE (@nfdi4bioimage@nfdi.social, @nfdi4bioimage@bird.makeup) #knowledgegraph and its function as a registry for public #OMERO image data repositories and their respective #SPARQL endpoints. Annotated #bioimage data has become part of the #semanticweb. @joshmoore @Andrawaag #nfdi #metadata #KnowledgeGraphs #ontop #r2rml #rdf
In today's ISE 2025 lecture,, we will introduce SPARQL as a query language for knowledge graphs. Again, I'm trying out 'Dystopian Novels' as example knowledge graph playground. Let's see, if the students might know any of them. Wtat do you think? ;-)

OK @doriantaylor (or anybody), one more beginner question. When does a reasoner actually do its work? So, I've got a pile of data in whatever form, and I formulate a query. Then .... what? The reasoner looks at the datatypes in the query and says e.g. "if you're asking for publications that also means books or articles?" Or does it create dummy nodes for the existing data, so there's a publication node for every book and every article?

Back in the lecture hall again after two exciting weeks of #ESWC2025 and #ISWS2025. This morning, we introduced our students to RDF, RDFS, RDF Inferencing, and RDF Reification.

It's a wrap! ISWS 2025 was a huge success! 60 wonderful students, 5 brilliant assistant tutors, 11 extraordinary tutors, 3 magnificent keynoters, and 2 visionary & unassuming directors. We've had a great time together with all of you and hope, you've had a safe trip home!

Memories from the last night gala dinner, selfie with some of the ISWS 2025 tutors. It was such a great time! We are missing you all already!
Kudos to our assistant tutors!
Without you this summerschool would never have been possible! You've did a marvellous job! Thank you so much!!!
