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.

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

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

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.
