Dear all,

I thank you for your efforts. I have to thank Dr. Andra Waagmeester, Dr. Finn Årup Nielsen and Dr. Egon Willighagen for their comments concerning the points I raised in Wikidata. These comments were useful to learn about ShEx project. I saw several papers about the project at http://labra.weso.es/ and I was honoured to see how it can provide schemas for Wikidata classes that can be later used to validate Wikidata. I ask if someone is interested in creating shape expressions of Medical Wikidata classes. As well, I tried to access http://wikidata-shex.wmflabs.org/w/index.php. However, it does not work. I ask about how to use Wikidata ShEx. I also ask if a tool can be developed to turn a Wikidata statement in red if it does not correspond to the shape expressions of the class of its subject.

Yours Sincerely,
