I'm not sure in this situation you'd want example fragments to be handled as a named graph type of first class object, but maybe I'm missing the use-case. Suppose I write <some-schema> a :Schema ; :example "@prefix some: <http://some.schema.example> .\n<bob> some:has <Thing> .\n" . Do I want those example triples to be accessible for e.g. in SPARQL queries? Or do I just want a convenient datatype to stash the literal text in RDF? - Steve On 2011-04-08, at 11:32, Richard Cyganiak wrote: > I just had a conversation with Ian Davis on Twitter that yielded a use case for defining datatype IRIs for graph literals.

SchemaPedia is a site that helps find RDF vocabularies, and it lists example usage snippets for the vocabularies. The site's back-end is RDF-based. Turtle literals are used to store the examples, as well as change events when examples are modified.
