'http://www.w3.org/ns/formats/Format' is a unique, top-level Class URI for specific file formats. Media types do not uniquely identify file formats (eg, serialization formats for various abstract concepts), because not all specific cases do have distinct media types, instances in this class can be used instead for proper identification.
Although the URI-s themselves refer to non-informational resources (ie, they are abstract identifiers), they can be dereferenced. Dereferencing leads to informational resources in XHTML, RDF/XML, or Turtle equivalents, depending on content negotiation.

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 JSON-LD is used to demonstrate the providers
available for File Formats. Some providers may use a different example, which is displayed in the table below.
A guide for curating additional providers can be found
