Dependency bumps:

2024-10-17 RELEASE 7.1.1

This minor release removes the dependency on some only Python packages, in particularsix which is a problem for some Linux distributions that ship RDFLib.

Other than that, there are a few minor PRs that improve testing and to do with making releases - no new RDFLib core work.

Merged PRs:

2024-10-17 RELEASE 7.1.0

This minor release incorporates just over 100 substantive PRs - interesting things submitted by people - and around 140 auto-generated update PRs from dependabot and similar.

There are no major changes in this release over 7.0.0 and this release can be used in place of 7.0.0 without much worry about altered behaviour.

Since the previous release, we have updated the way auto-generated PRs are handled to ease the job of maintainers.

2023-08-02 RELEASE 7.0.0

This is a major release with relatively slight breaking changes, new features and bug fixes.

The most notable breaking change relates to how RDFLib handles thepublicID parameter of the Graph.parse and Dataset.parse methods. Most users should not be affected by this change.

Instructions on adapting existing code to the breaking changes can be found in the upgrade guide from Version 6 to Version 7 which should be available here.

It is likely that the next couple of RDFLib releases will all be major versions, mostly because there are some more shortcomings of RDFLib's public interface that should be addressed.

If you use RDFLib, please consider keeping an eye ondiscussions, issues and pull-requests labelled with "feedback wanted".

A big thanks to everyone who contributed to this release.

BREAKING CHANGE: don't use publicID as the name for the default graph. (#2406)

Commit 4b96e9d, closes #2406.

When parsing data into a ConjunctiveGraph or Dataset, the triples in the default graphs in the sources were loaded into a graph named publicID.

This behaviour has been changed, and now the triples from the default graph in source RDF documents will be loaded into ConjunctiveGraph.default_context orDataset.default_context.

The publicID parameter to ConjunctiveGraph.parse and Dataset.parseconstructors will now only be used as the base URI for relative URI resolution.

BREAKING CHANGE: drop support for python 3.7 (#2436)

Commit 1e5f56b, closes #2436.

Python 3.7 will be end-of-life on the 27th of June 2023 and the next release of RDFLib will be a new major version.

This changes the minimum supported version of Python to 3.8.1 as some of the dependencies we use are not too fond of python 3.8.0. This change also removes all accommodations for older python versions.

feat: add curie method to NamespaceManager (#2365)

Commit f200722, closes #2365.

Added a curie method to NamespaceManager, which can be used to generate a CURIE from a URI.

Other changes:

Fixes #2348.

feat: add optional target_graph argument to Graph.cbd and use it for DESCRIBE queries (#2322)

Commit 81d13d4, closes #2322.

Add optional keyword only target_graph argument to rdflib.graph.Graph.cbd and use this new argument in evalDescribeQuery.

This makes it possible to compute a concise bounded description without creating a new graph to hold the result, and also without potentially having to copy it to another final graph.

feat: Don't generate prefixes for unknown URIs (#2467)

Commit bd797ac.

When serializing RDF graphs, URIs with unknown prefixes were assigned a namespace like ns1:. While the result would be smaller files, it does result in output that is not as readable.

This change removes this automatic assignment of namespace prefixes.

This is somewhat of an aesthetic choice, eventually we should have more flexibility in this regard so that users can exercise more control over how URIs in unknown namespaces are handled.

With this change, users can still manually create namespace prefixes for URIs in unknown namespaces, but before it there was no way to avoid the undesired behaviour, so this seems like the better default.

feat: Longturtle improvements (#2500)

Commit 5ee8bd7, closes #2500.

Improved the output of the longturtle serializer.

fix: SPARQL count with optionals (#2448)

Commit 46ff6cf, closes #2448.

Change SPARQL count aggregate to ignore optional that are unbound instead of raising an exception when they are encountered.

fix: GROUP_CONCAT handling of empty separator (issue) (#2474)

Commit e94c252, closes #2474.

GROUP_CONCAT was handling an empty separator (i.e. "") incorrectly, it would handle it as if the separator were not set, so essentially it was treated as a single space (i.e. " ").

This change fixes it so that an empty separator with GROUP_CONCATresults in a value with nothing between concatenated values.

Fixes #2473

fix: add NORMALIZE_LITERALS to rdflib.__all__ (#2489)

Commit 6981c28, closes #2489.

This gets Sphinx to generate documentation for it, and also clearly indicates that it can be used from outside the module.

fix: bugs with rdflib.extras.infixowl (#2390)

Commit cd0b442, closes #2390.

Fix the following issues in rdflib.extras.infixowl:

Other changes:

This code is based on code from:

fix: correct imports and __all__ (#2340)

Commit 7df77cd, closes #2340.

Disableimplicit_reexportand eliminate all errors reported by mypy after this.

This helps ensure that import statements import from the right module and that the __all__ variable is correct.

fix: dbpedia URL to use https instead of http (#2444)

Commit ef25896, closes #2444.

The URL for the service keyword had the http address for the dbpedia endpoint, which no longer works. Changing it to https as that works.

fix: eliminate bare except: (#2350)

Commit 4ea1436, closes #2350.

Replace bare except: with except Exception, there are some cases where it can be narrowed further, but this is already an improvement over the current situation.

This is somewhat pursuant to eliminatingflakeheaven, as it no longer supports the latest version of flake8 [ref]. But it also is just the right thing to do as bare exceptions can cause problems.

fix: eliminate file intermediary in translate algebra (#2267)

Commit ae6b859, closes #2267.

Previously, rdflib.plugins.sparql.algebra.translateAlgebra() maintained state via a file, with a fixed filename query.txt. With this change, use of that file is eliminated; state is now maintained in memory so that multiple concurrent translateAlgebra() calls, for example, should no longer interfere with each other.

The change is accomplished with no change to the client interface. Basically, the actual functionality has been moved into a class, which is instantiated and used as needed (once per call to algrebra.translateAlgebra()).

fix: eliminate some mutable default arguments in SPARQL code (#2301)

Commit 89982f8, closes #2301.

This change eliminates some situations where a mutable object (i.e., a dictionary) was used as the default value for functions in the rdflib.plugins.sparql.processor module and related code. It replaces these situations with typing.Optinal that defaults to None, and is then handled within the function. Luckily, some of the code that the SPARQL Processor relied on already had this style, meaning not a lot of changes had to be made.

This change also makes a small update to the logic in the SPARQL Processor's query function to simplify the if/else statement. This better mirrors the implementation in the UpdateProcessor.

fix: formatting of SequencePath and AlternativePath (#2504)

Commit 9c73581, closes #2504.

These path types were formatted without parentheses even if they contained multiple elements, resulting in string representations that did not accurately represent the path.

This change fixes the formatting so that the string representations are enclosed in parentheses when necessary.

fix: handling of rdf:HTML literals (#2490)

Commit 588286b, closes #2490.

Previously, without html5lib installed, literals withrdf:HTMLdatatypes were treated asill-typed, even if they were not ill-typed.

With this change, if html5lib is not installed, literals with therdf:HTML datatype will not be treated as ill-typed, and will haveNull as their ill_typed attribute value, which means that it is unknown whether they are ill-typed or not.

This change also fixes the mapping from rdf:HTML literal values to lexical forms.

Other changes:

Related issues:

fix: HTTP 308 Permanent Redirect status code handling (#2389)

Commit e0b3152, closes #2389 /docs.python.org/3.11/whatsnew/changelog.html#id128.

Change the handling of HTTP status code 308 to behave more likeurllib.request.HTTPRedirectHandler, most critically, the new 308 handling will create a new urllib.request.Request object with the new URL, which will prevent state from being carried over from the original request.

One case where this is important is when the domain name changes, for example, when the original URL is http://www.w3.org/ns/adms.ttl and the redirect URL ishttps://uri.semic.eu/w3c/ns/adms.ttl. With the previous behaviour, the redirect would contain a Host header with the value www.w3.org instead ofuri.semic.eu because the Host header is placed inRequest.unredirected_hdrs and takes precedence over the Host header inRequest.headers.

Other changes:

Fixes:

fix: lexical-to-value mapping of rdf:HTML literals (#2483)

Commit 53aaf02, closes #2483.

Use strict mode when parsing rdf:HTML literals. This ensures that whenlexical-to-value mapping(i.e. parsing) of a literal with rdf:HTML data type occurs, a value will only be assigned if the lexical form is a valid HTML5 fragment. Otherwise, i.e. for invalid fragments, no value will be associated with the literal [ref] and the literal will be ill-typed.

fix: TriG handling of GRAPH keyword without a graph ID (#2469)

Commit 8c9608b, closes #2469 /www.w3.org/2013/TriGTests/#trig-graph-bad-01.

The RDF 1.1 TriG grammar only allows the GRAPH keyword if it is followed by a graph identifier [ref].

This change enforces this rule so that the

http://www.w3.org/2013/TriGTests/#trig-graph-bad-01 test passes.

fix: TriG parser error handling for nested graphs (#2468)

Commit afea615, closes #2468 /www.w3.org/2013/TriGTests/#trig-graph-bad-07.

Raise an error when nested graphs occur in TriG.

With this change, the http://www.w3.org/2013/TriGTests/#trig-graph-bad-07 test passes.

fix: typing errors from dmypy (#2451)

Commit 10f9ebe, closes #2451.

Fix various typing errors that are reported when running with dmypy, the mypy daemon.

Also add a task for running dmypy to the Taskfile that can be selected as the default mypy variant by setting the MYPY_VARIANT environment variable to dmypy.

fix: widen Graph.__contains__ type-hints to accept Path values (#2323)

Commit 1c45ec4, closes #2323.

Change the type-hints for Graph.__contains__ to also accept Pathvalues as the parameter is passed to the Graph.triples function, which accepts Path values.

docs: Add CITATION.cff file (#2502)

Commit ad5c0e1, closes #2502.

The CITATION.cff file provides release metadata which is used by Zenodo and other software and systems.

This file's content is best-effort, and pull requests with improvements are welcome and will affect future releases.

docs: add guidelines for breaking changes (#2402)

Commit cad367e, closes #2402.

Add guidelines on how breaking changes should be approached.

The guidelines take a very pragmatic approach with known downsides, but this seems like the best compromise given the current situation.

For prior discussion on this point see:

docs: fix comment that doesn't describe behavior (#2443)

Commit 4e42d10, closes #2443.

Comment refers to a person that knows bob and the code would return a name, but this would only work if the triple person foaf:name bob . is part of the dataset

As this is a very uncommon way to model a foaf:knows the code was adjusted to match the description.

docs: recommend making an issue before making an enhancement (#2391)

Commit 63b082c, closes #2391.

Suggest that contributors first make an issue to get in principle agreement for pull requests before making the pull request.

Enhancements can be controversial, and we may reject the enhancement sometimes, even if the code is good, as it may just not be deemed important enough to increase the maintenance burden of RDFLib.

Other changes:

docs: remove unicode string form in rdflib/term.py (#2384)

Commit ddcc4eb, closes #2384.

The use of Unicode literals is an artefact of Python 2 and is incorrect in Python 3.

Doctests for docstrings using Unicode literals only pass because ALLOW_UNICODEis set, but this option should be disabled as RDFLib does not support Python 2 any more.

This partially resolves #2378.

2023-03-26 RELEASE 6.3.2

fix: ROUND, ENCODE_FOR_URI and SECONDS SPARQL functions (#2314)

Commit af17916, closes #2314.

ROUND was not correctly rounding negative numbers towards positive infinity,ENCODE_FOR_URI incorrectly treated / as safe, and SECONDS did not include fractional seconds.

This change corrects these issues.

fix: add __hash__ and __eq__ back to rdflib.paths.Path (#2292)

Commit fe1a8f8, closes #2292.

These methods were removed when @total_ordering was added, but@total_ordering does not add them, so removing them essentially removes functionality.

This change adds the methods back and adds tests to ensure they work correctly.

All path related tests are also moved into one file.

fix: Add to_dict method to the JSON-LD Context class. (#2310)

Commit d7883eb, closes #2310.

Context.to_dict is used in JSON-LD serialization, but it was not implemented. This change adds the method.

fix: add the wgs namespace binding back (#2294)

Commit adf8eb2, closes #2294.

#1686 inadvertently removed the wgs prefix. This change adds it back.

fix: change the prefix for https://schema.org/ back to schema (#2312)

Commit 3faa01b, closes #2312.

The default prefix for https://schema.org/ registered withrdflib.namespace.NamespaceManager was inadvertently changed to sdo in 6.2.0, this however constitutes a breaking change, as code that was using the schemaprefix would no longer have the same behaviour. This change changes the prefix back to schema.

fix: include docs and examples in the sdist tarball (#2289)

Commit 394fb50, closes #2289.

The sdists generated by setuptools included the docs and examplesdirectories, and they are needed for building docs and running tests using the sdist.

This change includes these directories in the sdist tarball.

A test:sdist task is also added to Taskfile.yml which uses the sdists to run pytest and build docs.

fix: IRI to URI conversion (#2304)

Commit dfa4054, closes #2304.

The URI to IRI conversion was percentage-quoting characters that should not have been quoted, like equals in the query string. It was also not quoting things that should have been quoted, like the username and password components of a URI.

This change improves the conversion by only quoting characters that are not allowed in specific parts of the URI and quoting previously unquoted components. The safe characters for each segment are taken fromRFC3986.

The new behavior is heavily inspired by

werkzeug.urls.iri_to_urithough there are some differences.

fix: JSON-LD context construction from a dict (#2306)

Commit 832e693, closes #2306.

A variable was only being initialized for string-valued inputs, but if a dictinput was passed the variable would still be accessed, resulting in aUnboundLocalError.

This change initializes the variable always, instead of only when string-valued input is used to construct a JSON-LD context.

fix: reference to global inside get_target_namespace_elements (#2311)

Commit 4da67f9, closes #2311.

get_target_namespace_elements references the args global, which is not defined if the function is called from outside the module. This commit fixes that instead referencing the argument passed to the function.

fix: restore the 6.1.1 default bound namespaces (#2313)

Commit 57bb428, closes #2313.

The namespaces bound by default by rdflib.graph.Graph andrdflib.namespace.NamespaceManager was reduced in version 6.2.0 of RDFLib, however, this also would cause code that worked with 6.1.1 to break, so this constituted a breaking change. This change restores the previous behaviour, binding the same namespaces as was bound in 6.1.1.

To bind a reduced set of namespaces, the bind_namespaces parameter ofrdflib.graph.Graph or rdflib.namespace.NamespaceManager can be used.

test: add webtest marker to tests that use the internet (#2295)

Commit cfe6e37, closes #2295.

This is being done so that it is easier for downstream packagers to run the test suite without requiring internet access.

To run only tests that does not use the internet, run pytest -m "not webtest".

The validation workflow validates that test run without internet access by running the tests inside firejail --net=none.

chore: Update CONTRIBUTORS from commit history (#2305)

Commit 1ab4fc0, closes #2305.

This ensures contributors are credited. Also added .mailmap to fix early misattributed contributions.

docs: fix typo in NamespaceManager documentation (#2291)

Commit 7a05c15, closes #2291.

Changed cdterms to dcterms, see #2196 for more info.

2023-03-18 RELEASE 6.3.1

This is a patch release that includes a singular user facing fix, which is the inclusion of the test directory in the sdist release artifact.

The following sections describe the changes included in this version.

build: explicitly specify packages in pyproject.toml (#2280)

Commit 334787b, closes #2280.

The default behaviour makes it more of a hassle to republish RDFLib to a separate package, something which I plan to do for testing purposes and possibly other reasons.

More changes may follow in a similar vein.

build: include test in sdist (#2282)

Commit e3884b7, closes #2282.

A perhaps minor regression from earlier versions is that the sdist does not include the test folder, which makes it harder for downstreams to use a single source of truth to build and test a reliable package. This restores the test folder for sdists.

docs: don't use kroki (#2284)

Commit bea782f, closes #2284.

The Kroki server is currently experiencing some issues which breaks our build, this change eliminates the use of Kroki in favour of directly using the generated SVG images which is checked into git alongside the PlantUML sources.

I also added a task to the Taskfile to re-generate the SVG images from the PlantUML sources by calling docker.

2021-07-20 RELEASE 6.0.0

6.0.0 is a major stable release that drops support for Python 2 and Python 3 < 3.7. Type hinting is now present in much of the toolkit as a result.

It includes the formerly independent JSON-LD parser/serializer, improvements to Namespaces that allow for IDE namespace prompting, simplified use of g.serialize() (turtle default, no need to decode()) and many other updates to documentation, store backends and so on.

Performance of the in-memory store has also improved since Python 3.6 dictionary improvements.

There are numerous supplementary improvements to the toolkit too, such as:

Working test suite with all tests passing.

Removed dependency on setuptools.

(Issue #43) Updated Package and Module Names to follow conventions outlined inhttp://www.python.org/dev/peps/pep-0008/

Removed SPARQL bits and non core plugins. They are mostly moving to http://code.google.com/p/rdfextras/ at least until they are stable.

Fixed datatype for Literal(True).

Fixed Literal to enforce constraint of having either a language or datatype but not both.

Fixed Literal's repr.

Fixed to Graph Add/Sub/Mul opterators.

Upgraded RDFa parser to pyRdfa.

Upgraded N3 parser to the one from CWM.

Fixed unicode encoding issue involving N3Parser.

N3 serializer improvements.

2007-04-04 RELEASE 2.4.0

Improved Literal comparison / equality

Sparql cleanup.

getLiteralValue now returns the Literal object instead of the result of toPython(). Now that Literals override a good coverage of comparison operators, they should be passed around as first class objects in the SPARQL evaluation engine.

Added support for session bnodes re: sparql

Fixed prolog reduce/reduce conflict. Added Py_None IncRefs where they were being passed into Python method invocations (per drewp's patch)

Fixed sparql queries involving empty namespace prefix.

Fixed the selected variables sparql issue

The restriction on GRAPH patterns with variables has been relieved a bit to allow such usage when the variable is provided as an initial binding

Fix for OPTIONAL patterns. P1 OPT P2, where P1 and P2 shared variables which were bound to BNodes were not unifying on these BNode variable efficiently / correctly. The fix was to add bindings for 'stored' BNodes so they aren't confused for wildcards

Added support to n3 parser for retaining namespace bindings.

Fixed several RDFaParser bugs.

Added serializer specific argument support.

Fixed a few PrettyXMLSerializer issues and added a max_depth option.

Added bind function

Fixed type of Namespace re: URIRef vs. unicode

Improved ValueError message

Changed value method's any argument to default to True

Changed __repr__ to always reflect that it's an rdf.Literal -- as this is the case even though we now have it acting like the corresponding type in some casses

A DISTINCT was added to the SELECT clause to ensure duplicate triples are not returned (an RDF graph is a set of triples) - which can happen for certain join expressions.

Support for ConditionalAndExpressionList and RelationalExpressionList (|| and && operators in FILTER)

Fixed context column comparison. The hash integer was being compared with 'F' causing a warning:Warning: Truncated incorrect DOUBLE value: 'F'

applied patch inhttp://rdflib.net/issues/2006/12/13/typos_in_abstractsqlstore.py/issue

fix forhttp://rdflib.net/issues/2006/12/07/problems_with_graph.seq()_when_sequences_contain_more_than_9_items./issue

General code cleanup (removing redundant imports, changing relative imports to absolute imports etc)

Removed usage of deprecated bits.

Added a number of test cases.

Added DeprecationWarning for save method

refactoring of GraphPattern

ReadOnlyGraphAggregate uses Graph constructor properly to setup (optionally) a common store

Fixed bug with . (fullstop) in localname parts.

Changed Graph's value method to return None instead of raising an AssertionError.

Added FOPLRelationalModel - a set of utility classes that implement a minimal Relational Model of FOPL implemented as a SQL database (uses identifier/value interning and integer half-md5-hashes for space and index efficiency).

Changed MySQL store to use FOPLRelationalModel plus fixes and improvements.

Added more test cases.

Cleaned up source code to follow pep8 / pep257.

2006-02-27 RELEASE 2.3.1

2005-12-23 RELEASE 2.3.0

See http://rdflib.net/2.3.0/ for most up-to-date release notes

Added N3 support to Graph and Store.

Added Sean's n3p parser, and ntriples parser.

BerkeleyDB implementation has been revamped in the process of expanding it to support the new requirements n3 requirements. It also now persists a journal -- more to come.

detabified source files.

Literal and parsers now distinguish between datatype of None and datatype of "".

Store-agnostic 'fallback' implementation of REGEX matching (inefficient but provides the capability to stores that don't support it natively). Implemented as a 'wrapper' around any Store which replaces REGEX terms with None (before dispatching to the store) and whittles out results that don't match the given REGEX term expression(s).

Store-agnostic 'fallback' implementation of transactional rollbacks (also inefficient but provides the capability to stores that don't support it natively). Implemented as a wrapper that tracks a 'thread-safe' list of reversal operations (for every add, track the remove call that reverts the store, and vice versa). Upon store.rollback(), execute the reverse operations. However, this doesn't guarantee durability, since if the system fails before the rollbacks are all executed, the store will remain in an invalid state, but it provides Atomicity in the best case scenario.

2005-10-10 RELEASE 2.2.3

Fixed BerkeleyDB backend to commit after an add and remove. This should help just a bit with those unclean shutdowns ;)

Added Fourthought backend contributed by Chimezie Ogbuji.
