Prez API
The API for Prez

Prez is a data-configurable Linked Data API framework that delivers profiles of Knowledge Graph data according to the Content Negotiation by Profile standard.
Where's the UI?
Prez delivers data only - usually RDF but could be GeoJSON, XML etc. - and it delivers a special form of RDF which includes labels for all objects and predicates Prez can find in its database.
If you want a UI that can render Prez' labelled RDF as HTML and other fancy graphical widgets, see the Prez UI.
Data Validation
For Prez to deliver data via its various subsystems, the data needs to conform to some minimum requirements: you can't, for instance, run VocPrez without any SKOS ConceptSchemes defined!
Validation
All the profiles listed above provide validators that can be used with RDF data to test to see if it's valid. If it is, Prez will be just fine with it.
The profiles' validators are all available from the profiles themselves (navigate to the listings of other profile resources via the specification links above) and they are also loaded into the KurrawongAI SHACL Validator online tool which you can use without downloading or installing anything:
Look for the VocPrez Compounded and similar validators. The 'compounded' bit means that validator will validate data against all VocPrez and inherited requirements.
