User:Daniel Mietchen/ShEx for clinical trials

About

I am playing with Shape Expressions here and want to create a ShEx manifest for clinical trials.

Process

Here are the steps I followed:

• Explore some individual clinical trials
  • via https://tools.wmflabs.org/scholia/clinical-trial/
    • e.g. ASCOT (Q297324) 
• Explore properties currently being used on Wikidata items on clinical trials
  • as per https://w.wiki/MJc
    • note - desired query would be one that counts the number of times a property is used among all clinical trials, right? to rank the most popular?
      • Yes, and I am using https://w.wiki/MJv for that at the bottom
• Explore (read, validate, check) some of the Entity Schemas already existing on Wikidata
  • as per User:HakanIST/EntitySchemaList, perusing ShEx Primer and ShEx Specification and the ShEx2 Validator as needed
    • E188
    • E185
    • E184
    • E177
    • E173
    • E169
    • E167
    • E165
    • E154
    • E153
    • E42
    • E33
    • E27
    • E25
    • E3
    • E1
• Review how Wikidata Shape Expressions Inference works
  • https://tools.wmflabs.org/wd-shex-infer/job/15
• Running Wikidata Shape Expressions Inference for a random set of clinical trial items
  • https://tools.wmflabs.org/wd-shex-infer/job/56
    • while waiting for the job to finish, set up {{EntitySchema}} based on {{P}} in order to list schema examples conveniently above
  • The resulting ShEx is way too complex, so I went for a variant based on the above query for properties currently being used
• Validation via ShEx2 Validator
  • that gave errors once the ShEx got too long, so I had to drop some of the lesser used properties

Draft

• E189

Notes

• The result can now be compared to a more comprehensive variant of the above query for properties currently being used
• I also tested YASHE on the way and will probably look into it some more.
