Change Log
All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning and Keep a CHANGELOG.
v0.3.5 - 2020-06-01
Changed
- Upgrade to RDF.ex 0.8. With that Elixir versions < 1.8 are no longer supported.
- the SPARQL extension function registry is now implemented with the ProtocolEx library,
improving the performance of queries using SPARQL extension functions (including the
builtin casting functions); unfortunately this means the
SPARQL.ExtensionFunction.Registry.get_all/0
function to get all registered extension functions can no longer be supported
v0.3.4 - 2019-12-14
- Upgrade to RDF.ex 0.7
v0.3.3 - 2019-10-25
Fixed
- a bug in the BGP processing algorithm lead to wrong solutions when one triple pattern in a BGP had no solutions
v0.3.2 - 2019-09-08
Added
no_extension_detection_in_releases_warning
configuration which disables the
warning that not all extension functions may be detected in a release with the runtime system in interactive mode
Fixed
- Raise an error when the query uses an unknown prefix instead of producing an invalid query
v0.3.1 - 2019-07-15
Changed
- Use the new
RDF.Literal.matches?/3
function from RDF.ex 0.6.1 for theREGEX
function - with the fix from RDF.ex 0.6.1 XSD boolean with uppercase letters in the boolean lexical values are no longer valid
Fixed
- the
true
andfalse
keywords from the SPARQL language are case-insensitive - the new
RDF.Literal.matches?/3
function also fixes some Unicode escaping issues in regular expressions
v0.3.0 - 2019-04-06
Changed
- Replace the prefix management of SPARQL.ex with the new prefix management capabilities of RDF.ex 0.6
- Use the query prefixes as the prefixes of CONSTRUCTed graphs
v0.2.9 - 2019-03-06
Fixed
- the application failed to start in OTP releases (#2)
v0.2.8 - 2019-02-16
Added
- Support for negations with
MINUS
v0.2.7 - 2018-11-11
Added
- Support of the
CONSTRUCT
query form
Fixed
- various fixes on comparisons between
RDF.DateTime
s andRDF.Date
s
v0.2.6 - 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
v0.2.5 - 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
v0.2.4 - 2018-10-06
Added
- Support for group graph patterns, i.e. nested graph patterns and
FILTER
s 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
v0.2.3 - 2018-09-23
Added
- evaluation of
DISTINCT
andREDUCED
(the later having the semantics asDISTINCT
, i.e. no optimizations right now) - implementation of
String.Chars
protocol onSPARQL.Query
Changed
various refinements of default prefixes
- renamed the query-specific default prefixes option from
prefixes
todefault_prefixes
- setting
none
on thedefault_prefixes
option, removes the standard application-wide configured default prefixes SPARQL.Processor.query
(and theSPARQL.execute_query
alias) pass options downSPARQL.Query.new/2
, so it can also used withdefault_prefixes
- renamed the query-specific default prefixes option from
v0.2.2 - 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
v0.2.1 - 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)
v0.2.0 - 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 toSPARQL.Query.Result
- removed the previous
SPARQL.Query.Result
struct for single solutions; these are now represented as simple maps
v0.1.0 - 2018-03-19
Initial release
