Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project roughly adheres to Semantic Versioning.

[Unreleased]

Added

  • Turtle support for object lists, predicate-object lists, blank-node property lists, RDF collections, numeric literals, and boolean literals.
  • Store schema verification, backend label validation, and quad lookup indexes for first-time schema installs.
  • SPARQL 1.1 Query support for SELECT, ASK, CONSTRUCT, DESCRIBE, graph patterns, joins, OPTIONAL, UNION, MINUS, FILTER and EXISTS, VALUES, BIND, grouping, aggregates, projection expressions, property paths, dataset clauses, solution modifiers, built-in functions, and SERVICE queries.
  • Author-gated MySQL/PostgreSQL store tests and local W3C-style parser, serializer, store, and SPARQL fixtures.
  • RDF/XML support for typed node elements, xml:base, xml:lang, rdf:ID, rdf:nodeID, property attributes, parseType resource, collection, and XML literal forms, RDF lists, rdf:li, and RDF/XML reification.
  • Author-gated W3C RDF 1.1 RDF/XML positive and negative syntax tests.
  • Author-gated W3C SPARQL 1.1 Query syntax tests and W3C evaluation wrappers for aggregates, BIND, VALUES, casts, CONSTRUCT, EXISTS and negation, built-in functions, grouping, project expressions, property paths, and subqueries.
  • Author-gated W3C SPARQL 1.1 Update syntax tests.
  • SPARQL syntax parsing entrypoint via sparql_parse, with sparql_parse_query retained as an alias.
  • SPARQL Update syntax parsing via the shared SPARQL parser. Update execution is intentionally left for a later stage.
  • Semantic Web framework roadmap document covering major future RDF, SPARQL, validation, reasoning, store, and ergonomics work.
  • Turtle and N-Triples compliance tests for strict N-Triples grammar, Turtle long strings, single-quoted strings, escaped prefixed names, base IRI resolution, numeric forms, and N-Triples serializer escapes.
  • Author-gated W3C RDF 1.1 Turtle, N-Triples, and N-Quads syntax manifests and fixtures.
  • Public RDF graph and dataset utilities for canonicalization, isomorphism, set operations, patching, blank-node relabelling, skolemization, and scoped blank-node allocation.
  • Store transaction helpers, bulk loading, named graph management APIs, explicit find, statistics, diagnostics, and query planning explanation.
  • SPARQL Update execution for data updates, modify operations, graph management, WITH, LOAD, transactional execution, prepared updates, and SPARQL Protocol update requests.
  • SPARQL result serializers for XML, JSON, CSV, and TSV, plus streaming parser and serializer APIs for large inputs and outputs.
  • SPARQL diagnostics and prepared query APIs.
  • SPARQL Protocol HTTP(S) client for remote query and update endpoints, returning the same result shapes as local SPARQL execution.
  • RDFSchemaStore with RDFS subclass, subproperty, domain, range, and type entailment.
  • RDF Schema, OWL, RDF, and XSD vocabulary helpers, datatype canonicalization and value-space comparison helpers, prefix registries, an RDF builder DSL, and lightweight resource wrappers.
  • Example scripts for parser/store/SPARQL and builder/resource workflows, plus a published compliance matrix.
  • Pretty Turtle serializer with reusable serializer planning for subject ordering, predicate ordering, RDF list detection, and safe blank-node nesting.
  • TriG parser and pretty serializer for RDF datasets, including default RDF 1.1 example-3 style output plus wrap_default and graph_keyword serializer options, and author-gated W3C RDF 1.1 TriG tests.
  • Pretty RDF/XML serializer using the shared serializer planning for typed node elements, configured labelling predicates, collection parseType output, and safe blank-node nesting.
  • RDFStore.temp() convenience constructor for temporary std/db backed stores.
  • parse_rdf.zzs and serialize_rdf.zzs scripts for loading RDF into temporary, DSN-backed, or SQLite-backed stores and serializing them with built-in or dynamically loaded parser and serializer classes.

Fixed

  • Language-tagged literals now use rdf:langString internally and serialize without an invalid explicit datatype.
  • The temporary tests/runner.zzs harness was removed; zuzuzoo discovers .zzs tests under tests automatically.
  • SPARQL joins now compare repeated variables against the actual dynamic binding key instead of the literal key name.
  • SPARQL W3C result comparisons now cover exact term values, graph results, optional bindings, blank-node isomorphism, result ordering, and expected error cases.
  • N-Triples and N-Quads parsing now reject Turtle-only syntax such as directives, bare a, booleans, numerics, relative IRIs, and single-quoted strings.
  • Turtle parsing now keeps a as rdf:type only in predicate position, requires the correct directive terminator style, resolves base IRIs using RFC-style path handling, and handles long strings, single-quoted strings, Unicode escapes, stricter language tags, leading-dot decimals, and escaped prefixed-name punctuation.
  • Turtle parsing now handles SPARQL-style case-insensitive directives, sole blank-node property lists, repeated semicolons, escaped % in local names, local-name dot runs, stricter local-name starts, invalid decoded IRI escapes, and RFC 3986 IRI resolution with preserved empty path segments.
  • N-Triples serialization now escapes control characters and illegal IRI characters, escapes datatype IRIs, and rejects blank node labels that cannot be represented in N-Triples.
  • SPARQL prefix stripping now preserves same-line query and update bodies after BASE and PREFIX declarations.
