* Description
This layer adds support for RDF files in N3 and [[https://www.w3.org/TR/turtle/][Turtle syntax]] using [[https://bitbucket.org/nxg/ttl-mode][ttl-mode]]
and for [[https://www.w3.org/TR/sparql11-query/][SPARQL]] queries using [[https://github.com/ljos/sparql-mode][sparql-mode]].

SPARQL-mode supports the execution of queries. When first called, you will be
prompted for a SPARQL HTTP endpoint in the minibuffer, which defaults to
http://localhost:2020/. Once set, it will be used for all subsequent queries in
that buffer. Results will be displayed in another buffer in CSV format.

** Features:
- Provides an alternative way to search the web using SPARQL queries.
