Wikidata:WikiProject Schemas

Wikidata Schemas are formally described expectations on a set of Wikidata entities. Subsets of Wikidata can be tested to see whether or not they conform to a specific schema. Schemas are stored on a dedicated namespace and expressed in the Shape Expressions language (ShEx), using ShExC syntax. An alternative approach to schemas are property constraints. For a less technical explanation of schemas and to propose new schemas please see Wikidata:Schemas.

ShExEdit

A WikidataCon 2017 session on Shape Expressions (ShEx)

Shape Expressions (Q29377880) is a concise, formal modeling and validation language for RDF structures. ShEx can be used to define shapes within the RDF graph. In the case of Wikidata, this would be sets of properties, qualifiers and references that describe the domain being modeled.
