URL

A uniform resource locator (URL). This will perform some normalisation on the URL so that it’s sure to be using valid encoding/quoting, and to make sure the URL has a schema (e.g. http, https, …).

Matchable types allow properties to be compared with each other in order to assess entity similarity.

Pivot types are a stronger form of matchable types and can be used to find similar entities based on simple value lookups.
