- <p>The RDF Working Group has included the following
- features; these may be removed due to implementor feedback.

- <p><b><code>GRAPH</code> keyword</b></p>
- <p>In this version of TriG, but not previous versions,
- the keyword <code>GRAPH</code> may occur before graph
- names, as specified in the grammar.
- </p>
- <p>
- This feature aligns with the syntax of
- SPARQL, specifically SPARQL Update,
- so sections of a TriG document can be cut-and-pasted into SPARQL
- update requests, and people used to reading SPARQL can more
- easily understand TriG documents.</p>
- <p>
- This keyword may cause a syntax error in older parsers, so its
- use should be avoided until all likely TriG-consuming
- systems have updated parsers. Once updated parsers are
- widespread, the use of GRAPH keyword is suggested to
- provide alignment with SPARQL.</p>
-
- <p>
- This feature is marked as being "at risk", which means the Working Group
- seeks feedback from the community on whether to allow the
- <code>GRAPH</code> keyword. The group may remove this feature without
- publishing another Last Call Working Draft. Users with a strong
- preference or with information which might influence the Working Group's
- decision whether to keep this feature are encouraged to send feedback.</p>
- <p>Previous publications of Turtle and TriG
- already included <code>PREFIX</code> and <code>BASE</code> keywords.

- <p><b>Unenclosed Triples</b></p>
- <p>In this version of TriG, but not previous versions,
- triples in the default graph are allowed to
- occur without requiring enclosing braces (
- <code>{</code>...<code>}</code>).
- outside of any curly braces. </p>
- <p>
- This
- feature is provided in order to align the TriG syntax with the SPARQL
- syntax, to allow for cut-and-paste and for easier TriG comprehension by
- people working with SPARQL. It also makes TriG an extension of Turtle;
- a TriG file using bare triples and no named graphs is also a Turtle file
- (with the same semantics).
- </p>
- <p>
- Bare triples will not be understood by some older TriG parsers, so their
- use should be avoided until all likely TriG-consuming systems have
- updated parsers. Once updated parsers are widespread, the use of bare
- triples is suggested to provide alignment with SPARQL.
- </p>
- <p>
- This feature is marked as being "at risk", which means the Working Group
- seeks feedback from the community on whether to allow bare triple in
- TriG. The group might remove this feature without publishing another
- Last Call Working Draft. Users with a strong preference or with
- information which might influence the Working Group's decision whether
- to keep this feature are encouraged to send feedback.
