RDFlib 6.3.0

[aucampia]

2023-03-16 RELEASE 6.3.0

This is a minor release that includes bug fixes and features.

Important Information

• RDFLib will drop support for Python 3.7 when it becomes EOL on 2023-06-27,
  this will not be considered a breaking change, and RDFLib's major version
  number will not be changed solely on the basis of Python 3.7 support being
  dropped.

User facing changes

This section lists changes that have a potential impact on users of RDFLib,
changes with no user impact are not included in this section.

• Add chunk serializer that facilitates the encoding of a graph into multiple
  N-Triples encoded chunks.
  PR #1968.

• Fixes passing NamespaceManager in ConjunctiveGraph's method get_context().
  The get_context() method will now pass the NamespaceManager of ConjunctiveGraph to the namespace_manager attribute of the newly created context graph, instead of the ConjunctiveGraph object itself. This cleans up an old FIXME comment.
  PR #2073.

• InfixOWL fixes and cleanup.
  Closed issue #2030.
  PR #2024,
  and PR #2033.

  • rdflib.extras.infixowl.Restriction.__init__ will now raise a ValueError
    if there is no restriction value instead of an AssertionError.
  • Fixed numerous issues with
    rdflib.extras.infixowl.Restriction.restrictionKind which was essentially
    not working at all.
  • Fixed how rdflib.extras.infixowl.Property.__repr__ uses
    rdflib.namespace.OWL.
  • Removed rdflib.extras.infixowl.Infix.__ror__ and
    rdflib.extras.infixowl.Infix.__or__ as they were broken.
  • Removed unused rdflib.extras.infixowl.termDeletionDecorator.
  • Added rdflib.extras.infixowl.MalformedClassError which will replace
    rdflib.extras.infixowl.MalformedClass (which is an exception) in the next
    major version.
  • Eliminated the use of mutable data structures in some argument defaults.

• Fixed some cross-referencing issues in RDFLib documentation.
  Closed issue #1878.
  PR #2036.

• Fixed import of xml.sax.handler in rdflib.plugins.parsers.trix so that it
  no longer tries to import it from xml.sax.saxutils.
  PR #2041.

• Removed a pre python 3.5 regex related workaround in the REPLACE SPARQL
  function.
  PR #2042.

• Fixed some issues with SPARQL XML result parsing that caused problems with
  lxml. Closed issue #2035,
  issue #1847.
  PR #2044.

  • Result parsing from
    TextIO
    streams now work correctly with lxml installed and with XML documents that
    are not utf-8 encoded.
  • Elements inside <results> that are not <result> are now ignored.
  • Elements inside <result> that are not <binding> are now ignored.
  • Also added type hints to rdflib.plugins.sparql.results.xmlresults.

• Added type hints to the following modules:

  • rdflib.store.
    PR #2057.
  • rdflib.graph.
    PR #2080.
  • rdflib.plugins.sparql.*.
    PR #2094,
    PR #2133,
    PR #2265,
    PR #2097,
    PR #2268.
  • rdflib.query.
    PR #2265.
  • rdflib.parser and rdflib.plugins.parsers.*.
    PR #2232.
  • rdflib.exceptions.
    PR #2232
  • rdflib.shared.jsonld.*.
    PR #2232.
  • rdflib.collection.
    PR #2263.
  • rdflib.util.
    PR #2262.
  • rdflib.path.
    PR #2261.

• Removed pre python 3.7 compatibility code.
  PR #2066.

  • Removed fallback in case the shutil module does not have the move
    function.

• Improve file-URI and path handling in Graph.serialize and Result.serialize to
  address problems with windows path handling in Result.serialize and to make
  the behavior between Graph.serialize and Result.serialie more consistent.
  Closed issue #2067.
  PR #2065.

  • String values for the destination argument will now only be treated as
    file URIs if urllib.parse.urlparse returns their schema as file.
  • Simplified file writing to avoid a temporary file.

• Narrow the type of context-identifiers/graph-names from rdflib.term.Node to
  rdflib.term.IdentifiedNode as no supported abstract syntax allows for other
  types of context-identifiers.
  PR #2069.

• Always parse HexTuple files as utf-8.
  PR #2070.

• Fixed handling of Literal datatype to correctly differentiate between
  blank string values and undefined values, also changed the datatype of
  rdflib.term.Literal.datatype from Optional[str] to Optional[URIRef] now
  that all non-URIRef str values will be converted to URIRef.
  PR #2076.

• Fixed the generation of VALUES block for federated queries.
  The values block was including non-variable values like BNodes which resulted
  in invalid queries. Closed issue #2079.
  PR #2084.

• Only register the rdflib.plugins.stores.berkeleydb.BerkeleyDB as a store
  plugin if the berkeleydb module is present.
  Closed issue #1816.
  PR #2096.

• Fixed serialization of BNodes in TriG.
  The TriG serializer was only considering BNode references inside a single
  graph and not counting the BNodes subjects as references when considering if a
  BNode should be serialized as unlabeled blank nodes (i.e. [ ]), and as a
  result it was serializing BNodes as unlabeled if they were in fact referencing
  BNodes in other graphs.
  PR #2085.

• Deprecated rdflib.path.evalPath in favor of rdflib.path.eval_path which is
  PEP-8 compliant. PR #2046

• Added charset=UTF-8 to the Content-Type header sent when doing an update
  with SPARQLConnector. Closed issue
  #2095. PR
  #2112.

• Removed the rdflib.plugins.sparql.parserutils.plist class as it served no
  discernible purpose. PR #2143

• Changed the TriG serializer to not generate prefixes for empty graph IDs.
  Closed issue #2154.
  PR #2160.

• Fixed handling of relative context files in the JSON-LD parser.
  Closed issue #2164.
  PR #2165.

• Improved failure handling in when computing QName for an unbound namespace.
  PR #2169.

• Fixed a typo in the default bound namespace for DCTERMS.
  PR #2173.

• Add support for supplying a custom namespace manager to n3() methods.
  PR #2174.

• Fixed the query string parameters for SPARQLConnector when using POST method.
  PR #2180.

• Fixed extra keyword argument and header handling in SPARQLConnector that
  resulted in headers from SPARQLConnector.update polluting headers from
  SPARQLConnector.query vice versa.
  PR #2183

• Added version restrictions for dependencies.
  PR #2187

• Switch to using importlib for getting the version of RDFLib instead of
  hard-coding it in __version__.
  PR #2187.

• Removed non-runtime extras, for building documentation, running tests and
  other development operations the versions and dependencies are now
  managed with Poetry.
  PR #2187.

• Fixed a bug that occurred when VALUES was used outside a GROUP BY clause.
  PR #2188.

  Closed issue #1722.

  Closes issue #479.
  PR #2221.

• Fixed a bug in rdflib.tools.defined_namespace_creator that occurred when
  multiple rdfs:comment were present on one resource.
  PR #2254.
