Compare v0.2.9...v0.3.0

0.2.9 - 2019-03-06

Fixed

  • the application failed to start in OTP releases (#2)

Compare v0.2.8...v0.2.9

Compare v0.2.7...v0.2.8

0.2.7 - 2018-11-11

Added

  • Support of the CONSTRUCT query form

Fixed

Compare v0.2.6...v0.2.7

0.2.6 - 2018-10-30

Added

  • Support for alternative graph patterns with UNION
  • Support for assigning to variables with BIND

Changed

  • REDUCED no longer removes duplicates without projection (for performance reasons)

Fixed

  • DISTINCT did not work without projection

Compare v0.2.5...v0.2.6

0.2.5 - 2018-10-21

Added

  • Support for optional graph patterns via OPTIONAL
  • Support for the bound function

Fixed

  • errors during evaluation of function arguments were handled incorrectly, which led in particular to wrong behaviour of the COALESCE function
  • SPARQL.Query.Result.get/2 failed when the given variable was not in the results

Compare v0.2.4...v0.2.5

0.2.4 - 2018-10-06

Added

  • Support for group graph patterns, i.e. nested graph patterns and FILTERs in the middle of a graph patterns (which splits up a graph pattern)
  • SPARQL.Query.Result.get/2 as a short way for getting the solutions of a single variable

Fixed

  • FILTER expressions at the beginning of a graph pattern

Compare v0.2.3...v0.2.4

0.2.3 - 2018-09-23

Added

  • evaluation of DISTINCT and REDUCED (the later having the semantics as DISTINCT, i.e. no optimizations right now)
  • implementation of String.Chars protocol on SPARQL.Query

Changed

  • various refinements of default prefixes

    • renamed the query-specific default prefixes option from prefixes to default_prefixes
    • setting none on the default_prefixes option, removes the standard application-wide configured default prefixes
    • SPARQL.Processor.query (and the SPARQL.execute_query alias) pass options down SPARQL.Query.new/2, so it can also used with default_prefixes

Compare v0.2.2...v0.2.3

0.2.2 - 2018-09-22

Added

  • application-wide and query-specific ways to define default prefixes

Fixed

  • bug in the lexer grammar which caused a scanner error on lowercase distinct

Compare v0.2.1...v0.2.2

0.2.1 - 2018-09-17

Fixed

  • generated Erlang output files of Leex and Yecc are excluded from Hex package, which caused issues using the SPARQL.ex Hex package on OTP < 21 (because the package was released with OTP 21)

Compare v0.2.0...v0.2.1

0.2.0 - 2018-09-17

Added

  • SPARQL Query engine for executing queries against RDF.ex graphs (not complete yet; see Current state section in README)

Changed

  • Elixir versions < 1.6 are no longer supported
  • renamed the SPARQL.Query.ResultSet struct to SPARQL.Query.Result
  • removed the previous SPARQL.Query.Result struct for single solutions; these are now represented as simple maps

Compare v0.1.0...v0.2.0

v0.1.0 - 2018-03-19

Initial release
