This service fills a gap between services like prefix.cc and LOV or looking up the original vocabulary specification. Not all vocabularies (or schema or ontology, whatever you want to call them) provide an HTML view. If you resolve some of the common prefixes all you get back is some RDF serialization which is not ideal. (from https://prefix.zazuko.com/about)

Providers

A provider turns a local unique identifiers from a resource into a URI. Many providers are also resolvable as URLs (i.e., they can be used in a web browser).

The local unique identifier frbr is used to demonstrate the providers available for Zazuko Prefix Server. A guide for curating additional providers can be found here.
