💖 RDF::Query::Algebra::Service — bestie edition 💖

okay so this is a page from the User Contributed Perl Documentation, and it's all about RDF::Query::Algebra::Service — the manual page you're looking at is RDF::Q...ervice(3pm) (they truncated it, tragic, but she's fine). This class is the algebra class for SERVICE (federation) patterns. group chat for your SPARQL queries, basically. 🌐✨

✨ NAME ✨

RDF::Query::Algebra::Service — the Algebra class for SERVICE (federation) patterns. 🫶

🌸 VERSION 🌸

This document describes RDF::Query::Algebra::Service version 2.919. that's the one, no cap. 📌

💅 METHODS 💅

so beyond the methods we're about to spill below, this class inherits methods from the RDF::Query::Algebra class. she's got family. 🧬

  • new ( $endpoint, $pattern, $silent ) — returns a brand new Service structure. fresh out the box. ✨
  • construct_args — returns a list of arguments that, if you pass them to this class' constructor, will produce a clone of this algebra pattern. it's giving photocopier energy. 🖨️
  • endpoint — returns the endpoint resource of the named graph expression. 📍
  • pattern — returns the graph pattern of the named graph expression. 🧩
  • silent — returns true if the service operation is to ignore errors during execution. live laugh let the errors go 🫣
  • lhs — if the SERVCE operation uses a variable endpoint, then it gets treated like a binary operator: it executes the left-hand-side pattern first, and uses the results from it to bind endpoint URL values that get used in SERVICE evaluation. (also yes, the original says "SERVCE" — iconic typo, we're keeping it, she's part of the lore now 💀) 🔗
  • sse — returns the SSE string for this algebra expression. 🎀
  • as_sparql — returns the SPARQL string for this algebra expression. 🪄
  • as_hash — returns the query as a nested set of plain data structures. and by plain we mean no objects, bestie, just data. 🍓
  • type — returns the type of this algebra expression. what's her vibe? this tells you. 🔍
  • referenced_variables — returns a list of the variable names used in this algebra expression. 👀
  • potentially_bound — returns a list of the variable names used in this algebra expression that will bind values during execution. maybe-bound, potentially iconic. 💫
  • definite_variables — returns a list of the variable names that will be bound after evaluating this algebra expression. no maybes here, this is a commitment. 👑
  • qualify_uris ( \%namespaces, $base_uri ) — returns a new algebra pattern where all referenced Resource nodes that represent QNames (ns:local) get qualified using the supplied %namespaces. glow-up for your URIs, periodt. 🌈

friendly reminder bestie: every flag, value, default, path and code snippet in here is copy-pasted-with-love straight from the real page — the vibe is mine, the facts are hers. 🫶

and that's the whole page!! this one's perl v5.40.1, dated 2025-08-18 — take care of her, she's doing federation work out here. bye bestie, go slay some SERVICE patterns for me 🌸💖✨
