This year we will have another edition of the @VAIA #UGent #course on #LinkedData and #Solid !

This course touches the basics of Linked Data, #KnowledgeGraph, #RML, #SHACL, #ShEx, Solid, and #ontologies so you can use these technologies in your own products!

#Wikidata popularized #SPARQL to query RDF by providing open tools and data to play with. I guess it will be similar with #SheX to validate RDF (to some lesser degree because validation is less fun). See https://www.wikidata.org/wiki/Wikidata:Schemas for details

Just came across LinkML, a flexible modeling language allowing you to author schemas in #YAML that describe the structure of your data.
Validate/generate #JSON, #JSONLD, #RDF, #SPARQL, #SHACL, #ShEx, #OWL.

Thanks to #omeNGFF for heads-up

Today I talked (and learned) about various forms of cancer, cotton, and moth detection and their description all through the common backbone of the semantic web. While being tired from a day of back-to-back (zoom) meetings, I do love my job. So much potential in #Wikidata #RDF #SPARQL #SHEX

I was told that Moths are child taxa of the taxon Lepidoptera, except those that are butterflies (Papilionoidea). Trying to get all moths from #Wikidata would be possible by the #SPARQL query below, which times out.

I created a subset from #wikidata using #ShEx https://doi.org/10.5281/zenodo.7662320.
Loaded the triples into a #Graphdb instance and I am happy because I can now explore the #Moth space on #wikidata.
All on my KDE #slimbook (https://kde.slimbook.es/)

I am really happy with the results from the #biohack22 last week. I can now extract subsets from #wikidata using #ShEx. E.g the extracted subset of the #GeneWiki subset from #wikidata https://zenodo.org/record/7316825#.Y3KoyezMKEu #10.5281/zenodo.7316825

I started working on #ShEx shapes to validate whether a SKOS file is ready to be published with #SkoHub. Unfortunately, the tooling does not seem to be that great yet. For example, I have problems with the few online validators that are around.

Does anybody know of a good SheX validator for the command line?
