Using IndeGx and our endpoint catalog, I surveyed the usage of #RDF, #RDFS, #OWL, #SWRL, #SHACL, #SPIN, and #SKOS over 320 endpoints.
Some insights:
- Only 2 endpoints do not use RDF, one seems to have gone down during tests, and the other uses only Schema
- 11 endpoints use exclusively RDF
- Endpoints use an average of 3.8 of the listed vocabularies
- By far, the most used are RDF, RDFS, OWL and SKOS
- All vocabularies are used together at least once

What if OWL is not enough? In this hands-on tutorial of our #kg2023 lecture @sashabruns is showing you how to create and exploit SWRL rules with protégé.

In the next section of our #kg2023 lecture you will learn about the Semantic Web Rule Language SWRL, adding the potential of logical rules to the description logics based #SemanticWeb technology stack.

So etwas umzusetzen macht natürlich Arbeit. Aber es könnte potenziell viele Menschen vor Erkrankung und ggf. Tod schützen. Und die Technologie könnte sich auf andere Rechtstexte bzw. Wissensgebiete übertragen lassen. ⇒ These: Es wurde schon Arbeit in sinnlosere Projekte gesteckt. 😉
