✨ RDF::TriN3 ✨

okay bestie, welcome to RDF::TriN3 — this is a Perl manpage, section 3pm, and it is literally the Notation 3 extensions for RDF::Trine. buckle up 🎀

💖 NAME 💖

RDF::TriN3 — notation 3 extensions for RDF::Trine. yes that's the whole name. short, sweet, iconic. 👑

🌸 DESCRIPTION 🌸

so this module extends RDF::Trine in three ways, no cap:

  • Adds a Notation 3 parser. 🧚
  • Adds a Notation 3 serializer. ✨
  • Provides a subclass of literals to represent Notation 3 formulae. 💅

and like, in addition to all that, a parser is also provided for Notation 3 extended with ShorthandRDF notation — that's <http://esw.w3.org/ShorthandRDF>. obsessed. 🦋

😭 BUGS AND LIMITATIONS 😭

okay so here's the part where we keep it real. ngl, there are some limits and you need to know about them.

Implementing N3 logic and the cwm built-ins is considered outside the scope of this distribution. the author says they're interested in doing that as part of a separate project though, so like… someday maybe. 🙈

RDF::TriN3 currently relies entirely on RDF::Trine to provide implementations of the concept of graphs, and storage. so any graphs that can't be represented using RDF::Trine can't be represented in RDF::TriN3. RDF::Trine's graph model is a superset of RDF, but a subset of Notation 3's model. and the way that while this allows literal subjects, and literal and blank node predicates — those may not be supported by all storage engines. also top-level variables (?foo), and top-level @forSome and @forAll (i.e. not nested inside a formula) might cause problems. 💀

RDF::Trine::Store::DBI has some issues with literal subjects, and literal and blank node predicates, allowing them to be stored, but not retrieved. from version 0.128, RDF::Trine::Store::DBI offers a clear_restrictions method that should resolve these issues. RDF::Trine::Store::Memory is fine. other stores are not tested. 🫶

please report any bugs to <http://rt.cpan.org/>. do it bestie, the maintainer wants to know. 💌
