We are conducting a #survey to better understand the challenges, experiences, and practical applications of validating #RDF data using #SHACL and #ShEx.
Please help us get a better overview by sharing your insights:
https://forms.gle/LdXsG644obcgSsAE6
It only takes around 8 minutes.
Google DocsRDF Shape Languages SurveyHow long does this survey take to fill in?
Approximately 8 minutes. Please note that half of the questions are skippable.
What is the purpose of the study?
The purpose of the study is to gather empirical data to better understand the landscape of RDF shape languages and their use, particularly with respect to the two most common validation languages SHACL and ShEx.
Why have I been asked to take part?
You have been asked to participate because you have worked with SHACL or ShEx.
Do I have to take part?
No, participation in this study is entirely up to you. You can withdraw from the study at any time, without giving a reason.
What will happen to the results of this study?
We will share the results of this study in a summarized form with participants and the community, potentially in the form of a blogpost or publication.

Shape Expressions (#ShEx) in the #Wikidata knowledge graph supported today. #Synia overview: https://synia.toolforge.org/#shex

A tidbit from #wmhack: #WikiWorks and MediaWiki developer Techwizzie (Sanjay Thiyagarajan) created a proof-of-concept userscript to help editors enhance existing items, using 'properties for this type' (P1963) to prompt for relevant additions: https://www.wikidata.org/wiki/User:Techwizzie/newInterface.js
If extended to use claims from 'subclass of' as well, it may provide a viable approach to dynamic shape-like editing assistance on #Wikidata (where such properties already exist), as an alternative to more formal #ShEx definitions.

I am happy to see blog planets are still a thing. I found a few active planets:
- Planet Debian: https://www.wikidata.org/wiki/Q121135094 #debian
- Planet Python: https://www.wikidata.org/wiki/Q121135640 #python
- Planet Classpath: https://www.wikidata.org/wiki/Q121140438 #java
- Planet GNOME: https://www.wikidata.org/wiki/Q121143001 #gnome
- Planet Freedesktop: planet.freedesktop.org #freedesktop
- Planet Wikimedia: https://www.wikidata.org/wiki/Q121143049 #wikimedia
Here's the shape expression I've been using: https://www.wikidata.org/wiki/EntitySchema:E405 #shex

@egonw @OpenRefine @Andrawaag in this direction (exporting from #OpenRefine to #ShEx) it could perhaps work - but it probably depends on what you want to do with the ShEx afterwards. There is some discussion as to why we couldn't use ShEx as our notion of "schema with missing parts": https://www.wikidata.org/wiki/Wikidata_talk:Schemas#Feedback_from_the_%22Entity_Schema_build-out_and_integration%22_task_of_WMDE's_development_plan,_and_OpenRefine

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

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.

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?
