Re: [Wikidata] Shape Expressions arrive on Wikidata on May 28th

The history of ShEx is quite complex. I don't think that one can say that there were complete and conforming implementations of ShEx in 2017 because the main ShEX specification, http://shex.io/shex-semantics-20170713/ was ill-founded. I pointed this out in

Hello, Could you explain why the non-standard ShEx has been chosen rather than the W3C Recommendation SHACL? I would assume that if one has several options for bringing a functionality to something that largely promotes interoperability (like Wikidata), the default choice should be a

Re: [Wikidata] Shape Expressions arrive on Wikidata on May 28th

I really don't see the issue here. SHACL, like ShEx is a language to express data shapes. I adopted using ShEx in a wikidata context 2016 when ShEx was demonstrated at a tutorial at the SWAT4HCLS conference [1] in Amsterdam, where it was discussed in both a tutorial and a hackathon topic. At that

Re: [Wikidata] Shape Expressions arrive on Wikidata on May 28th

It is not really possible to determine what a reasonable shape is before determining which Wikidata items are considered to be instances of human. For example, bog body (Q199414) is a subclass of human (Q5) but its instances are quite different from other instances human. In any case, shouldn't

Thanks for your feedback! There is already a ticket about adding a new data type allowing to link EntitySchemas from statements: https://phabricator.wikimedia.org/T214884 If we don't encounter any major technical issue, this could be done in the incoming weeks. On Tue, 28 May 2019 at 19:18, James

Re: [Wikidata] Shape Expressions arrive on Wikidata on May 28th

Anyone know of a Language Server & Client for ShEx in Javascript ? It would be great to have one so all IDE's can take advantage of it. https://code.visualstudio.com/api/language-extensions/overview I've opened an issue on github:shexSpec/shex.js to inquire as well...

Re: [Wikidata] Shape Expressions arrive on Wikidata on May 28th

The schemas can strike a practical balance between capturing current practice and describing a todo list of things to fix on current practice. It's possible we will want to separate those roles. In the meantime, can you survey existing instances and propose a shape which is not too far from the

Re: [Wikidata] Shape Expressions arrive on Wikidata on May 28th

I sure hope that E10 is *not* the shape for human. It certainly isn't a correct shape for humans that belong to subclasses of human (such as Old Croghan Man (Q166790) or Delina Filkins (Q1408186)). E10 is also currently silent on what information should be present for humans, which I take it to

Hello all, As previously announced, we just released shape expressions on Wikidata. You can for example have a look at E10, the shape for human , or create a new EntitySchema . A few useful

Wonderful! Awesome! Thank you very much, Léa, to announce us this arrival. And, of course, thank you to everyone who is working in this project. I think ShEx is going to help to make the data of Wikidata more consistent and trustworthy. I am wishing to learn how to create and use this ShEx

Re: [Wikidata] Shape Expressions arrive on Wikidata on May 28th

I definitely think this is a big step forward that will reduce maintenance effort, will boost consensus processes on how to represent knowledge on Wikidata and will ensure that the data is consistently represented so that it can be processed unambiguously and automagically to an extent previously
