API Platform is a popular and easy to use semantic web framework:
1. You design your data model as a set of PHP classes, or you generate the class from any RDF vocabulary such as Schema.org
2. API Platform uses the classes to expose a JSON-LD API with with all the typical features (sorting, filtering, pagination…)
3. You use the provided "smart clients" to build a dynamic admin interface or to scaffold Next, Nuxt or React Native apps (these tools rely on the Hydra API description vocabulary, and work with any Hydra-enabled API)
In addition to RDF/JSON-LD/Hydra, API Platform also supports ActivityPub.
