I just had a conversation with Ian Davis on Twitter that yielded a use case for defining datatype IRIs for graph literals. I thought I'd share it as input into ISSUE-5 [1].

He uses Turtle snippets as literals in SchemaPedia [2]. 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. See [3] for a typical change event.

Currently Ian uses plain literals, because no datatype was readily available.

The idea of abusing Ivan's format URIs from [4] came up.
