Changelog

v0.3.0

• Add support for SPARQL collections syntactic sugar:
  • Add support for RDF list syntax.
  • Add support for blank node vector syntax.
• Modify the AST tree for triples to support the aforementioned features and to remove redundant nodes in the tree.
• Rework blank node validation to make the implementation simpler (this results in minor changes to the error output).
• Disallow syntax-quoting for symbols.
• Fix bug where timestamps with zeroed-out seconds have the seconds omitted.

v0.2.1

• Update GitHub Actions CI and CD to remove deprecation warnings.

v0.2.0

• Rework IRI, variable, blank node and literal implementations and add support for additional Java(Script) types.
  • Implement protocols to define validation and formatting behavior IRIs, variables, blank nodes and literals, and apply extend-type/extend-protocol to default types.
  • Add support for java.net.URI and js/URL IRI instances.
  • Add support for java.time.Temporal timestamps (e.g. LocalDateTime and ZonedDateTime).
  • Refine datatypes for numeric literals, e.g. Clojure integers are associated with xsd:long by default.
  • Refine datatypes for date- and time-only timestamps, e.g. java.sql.Date and java.sql.Time are now associated with xsd:date and xsd:time, respectively. (Breaking!)
• Add :force-iris? optional arg in order to force datatype IRIs to be appended when formatting literals (with the exception of language-tagged strings).
• Add support for Unicode characters and percent encoding.
  • Unicode characters are now supported in symbols and keywords.
  • Percent encoding is allowed in prefixed IRI keyword names.
  • (Clojure-only) Optimize string validation.
• Replace certain uses of s/or with multi-specs in order to simplify error messages.

v0.1.2

• Fix a bug where certain SPARQL Update clauses - LOAD, CLEAR, CREATE, and DROP - were not being correctly formatted.
  • The form [:graph iri] is now mandatory for the aforementioned Update clauses and optional for others (ADD, MOVE, AND COPY).
• Fix validation of strings containing escaped char sequences such as \\n or \\r.
  • Special thanks to @quoll for their assistance with this bugfix.

v0.1.1

Fix a number of bugs discovered in v0.1.0 (see Pull Request #20):

• Allow IRIs and prefixed IRIs to be used in expressions.
• Fix zipper traversal not working correctly with deletion or insertion quads.
• Fix java.time.Instant instances not being formatted correctly.
• Fix a not being valid in DELETE or INSERT queries.
• Fix incorrect predicate specs for triples that restrict both blank nodes and variables.
• Ensure parentheses are properly added around negated property paths.
• Ensure parentheses around expressions are added for certain clauses (e.g. FILTER).

Apply updates to the documentation:

• Fix incorrect documentation on the CONSTRUCT WHERE query.
• General grammar and cleanup fixes.
