Not/Yet/Released RELEASE 2.5.0 (Issue #43) Updated Package and Module Names for follow conventions outlined in http://www.python.org/dev/peps/pep-0008/ (Issue #58) Removed a stderr print inside the SQLite store implementation. (Issue #8) Replaced C based SPARQL parser with a pure Python one. 2009/03/30 RELEASE 2.4.1 Fixed Literal comparison case involving Literal's with datatypes of XSD.base64Binary. Fixed case where XSD.date was matching before XSD.dateTime for datetime instances. Fixed jython interoperability issue (issue #53). Fixed Literal repr to handle apostrophes correctly (issue #28). Fixed Literal's repr to be consistent with its __init__ (issue #33). 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 invokations (per drewp's patch) Fixed sparql queries involving empty namespace prefix. Fixed the selected variables sparql issue Fixed support in SPARQL queries. Fixed involving multiple unions and queries are nested more than one level (bug in _getAllVariables causing failure when parent.top is None) Fixed test_sparql_equals.py. Fixed sparql json result comma errors issue. Fixed test_sparql_json_results.py (SELECT * variables out of order) Added a 4Suite-based SPARQL XML Writer implementation. If 4Suite is not installed, the fallback python saxutils is used instead applied patch from http://rdflib.net/issues/2007/02/23/bugs_in_rdflib.sparql.queryresult/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. Fixed some TurtleSerializer issues. Fixed some N3Serializer issues. Added support easy_install added link to long_descriptin for easy_install -U rdflib==dev to work; added download_url back added continuous-releases-using-subversion bit Added rdflib_tools package Added rdfpipe Added initial EARLPluging Improved test running... using nose... added tests Exposed generated test cases for nose to find. added bit to configure 'setup.py nosetests' to run doc tests added nose test bits Added md5_term_hash method to terms. Added commit_pending_transaction argument to Graph's close method. Added DeprecationWarning to rdflib.constants Added a NamespaceDict class for those who want to avoid the Namespace as subclass of URIRef issues 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 in http://rdflib.net/issues/2006/12/13/typos_in_abstractsqlstore.py/issue fix for http://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. Fixed conversion of (exiplicit) MySQL ports to integers. Fixed MySQL store so it properly calculates __len__ of individual Graphs Aligned with how Sleepycat is generating events (remove events are expressed in terms of interned strings) Added code to catch unpickling related exceptions Added BerkeleyDB store implementation. Merged TextIndex from michel-events branch. 2006/10/15 RELEASE 2.3.3 Added TriXParser, N3Serializer and TurtleSerializer. Added events to store interface: StoreCreated, TripleAdded and TripleRemoved. Added Journal Reader and Writer. Removed Sleepycat level journaling. Added support for triple quoted Literal's. Fixed some corner cases with Literal comparison. Fixed PatternResolution for patterns that return contexts only. Fixed NodePickler not to choke on unhashable objects. Fixed Namespace's __getattr__ hack to ignore names starting with __ Added SPARQL != operator. Fixed query result __len__ (more efficient). Fixed and improved RDFa parser. redland patches from http://rdflib.net/pipermail/dev/2006-September/000069.html various patches for the testsuite - http://rdflib.net/pipermail/dev/2006-September/000069.html 2006/08/01 RELEASE 2.3.2 Added SPARQL query support. Added XSD to/from Python datatype support to Literals. Fixed ConjunctiveGraph so that it is a proper subclass of Graph. Added Deprecation Warning when BackwardCompatGraph gets used. Added RDFa parser. Added Collection Class for working with RDF Collections. Added method to Graph for testing connectedness Fixed bug in N3 parser where identical BNodes were not being combined. Fixed literal quoting in N3 serializer. Fixed RDF/XML serializer to skip over N3 bits. Changed Literal and URIRef instanciation to catch UnicodeDecodeErrors - which were being thrown when the default decoding method (ascii) was hitting certain characters. Changed Graph's bind method to also override the binding in the case of an existing generated bindings. 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 Added save method to BackwardCompatibleGraph so that example.py etc work again. Applied patch from Drew Perttula to add local_time_zone argument to util's date_time method. Fixed a relativize bug in the rdf/xml serializer. Fixed NameError: global name 'URIRef' is not defined error in Sleepycat.py by adding missing import. Applied patch for Seq to sort list by integer, added by Drew Hess. Added a preserve_bnode_ids option to rdf/xml parser. Applied assorted patches for tests (see http://tracker.asemantics.com/rdflib/ticket/8 ) Applied redland.diff (see http://tracker.asemantics.com/rdflib/ticket/9 ) Applied changes specified http://tracker.asemantics.com/rdflib/ticket/7 Added a set method to Graph. Fixed RDF/XML serializer so that it does not choke on n3 bits (rather it'll just ignore them) 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. Sleepycat 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 capablity 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 Sleepycat backend to commit after an add and remove. This should help just a bit with those unclean shutdowns ;) Fixed use of logging so that it does not mess with the root logger. Thank you, Arve, for pointing this one out. Fixed Graph's value method to have default for subject in addition to predicate and object. Fixed Fourthought backend to be consistent with interface. It now supports an empty constructor and an open method that takes a configuration string. 2005/09/10 RELEASE 2.2.2 Applied patch from inkel to add encoding argument to all serialization related methods. Fixed XMLSerializer bug regarding default namespace bindings. Fixed namespace binding bug involving binding a second default namespace. Applied patch from Gunnar AAstrand Grimnes to add context support to __iadd__ on Graph. (Am considering the lack of context support a bug. Any users currently using __iadd__, let me know if this breaks any of your code.) Added Fourthought backend contributed by Chimezie Ogbuji. Fixed a RDF/XML parser bug relating to XMLLiteral and escaping. Fixed setup.py so that install does not try to uninstall (rename_old) before installing; there's now an uninstall command if one needs to uninstall. 2005/08/25 RELEASE 2.2.1 Fixed issue regarding Python2.3 compatibility. Fixed minor issue with URIRef's absolute method. 2005/08/12 RELEASE 2.1.4 Added optional base argument to URIRef. Fixed bug where load and parse had inconsistent behavior. Added a FileInputSource.

Added namespaces method that is a generator over all prefix, namespace bindings. Added notion of NamespaceManager. Added couple new backends, IOMemory and ZODB. 2005/03/19 RELEASE 2.0.6 Added pretty-xml serializer (inlines BNodes where possible, typed nodes, Collections). Fixed bug in NTParser and n3 methods where not all characters where being escaped. Changed label and comment methods to return default passed in when there is no label or comment. Moved methods to Store Class. Store no longer inherits from Schema. Fixed bug involving a case with rdf:about='#' Changed InMemoryBackend to update third index in the same style it does the first two. 2005/01/08 RELEASE 2.0.5 Added publicID argument to Store's load method. Added RDF and RDFS to top level rdflib package. 2004/10/14 RELEASE 2.0.4 Removed unfinished functionality. Fixed bug where another prefix other than rdf was getting defined for the rdf namespace (causing an assertion to fail). Fixed bug in serializer where nodeIDs were not valid NCNames. 2004/04/21 RELEASE 2.0.3 Added missing "from __future__ import generators" statement to InformationStore. Simplified RDF/XML serializer fixing a few bugs involving BNodes. Added a reset method to RDF/XML parser. Changed 'if foo' to "if foo is not None" in a few places in the RDF/XML parser. Fully qualified imports in rdflib.syntax {parser, serializer}. Context now goes through InformationStore (was bypassing it going directly to backend). 2004/03/22 RELEASE 2.0.2 Improved performance of Identifier equality tests. Added missing "from __future__ import generators" statements needed to run on Python2.2. Added alternative to shlib.move() if it isn't present. Fixed bug that occured when specifying a backend to InformationStore's constructor. Fixed bug recently introduced into InformationStore's remove method. 2004/03/15 RELEASE 2.0.1 Fixed a bug in the SleepyCatBackend multi threaded concurrency support. (Tested fairly extensively under the following conditions: multi threaded, multi process, and both). NOTE: fix involved change to database format -- so 2.0.1 will not be able to open databases created with 2.0.0 Removed the use of the Concurrent wrapper around InMemoryBackend and modified InMemoryBackend to handle concurrent requests. (Motivated by Concurrent's poor performance on bigger TripleStores.) Improved the speed of len(store) by making backends responsible for implementing __len__. Context objects now have a identifier property. 2004/03/10 RELEASE 2.0.0 Fixed a few bugs in the SleepyCatBackend multi process concurrency support.

Added versions of remove, remove_triples and triples methods to the BackwardCompatility mixin for TripleStores that take an s, p, o as opposed to an (s, p, o). 2003/02/03 RELEASE 1.2.1 Added support for parsing XMLLiterals. Added support for proper charmod checking (only works in Python2.3). Fixed remaining rdfcore test cases that where not passing.

BNode prefix is now composed of ascii_letters instead of letters. Added a bsddb backed InformationStore. Added an asyncronous load method, methods for scheduling context updates, and a run method. 2002/12/16 RELEASE 1.1.5 Introduction of InformationStore, a TripleStore with the addition of context support. Resource __getitem__ now returns object (no longer returns a Resource for the object). Fixed bug in parser that was introduced in last release regaurding unqualified names. 2002/12/10 RELEASE 1.1.4 Interface realigned with last stable release. Serializer now uses more of the abbreviated forms where possible. Parser optimized and cleaned up. Added third index to InMemoryStore. The load and parse methods now take a single argument. Added a StringInputSource for to support parsing from strings. Renamed rdflib.BTreeTripleStore.TripleStore to rdflib.BTreeTripleStore.BTreeTripleStore. Minor reorganization of mix-in classes. 2002/12/03 RELEASE 1.1.3 BNodes now created with a more unique identifier so BNodes from different sessions do not collide. Added initial support for XML Literals (for now they are parsed into Literals). Resource is no longer a special kind of URIRef. Resource no longer looks at range to determine default return type for __getitem__. Instead there is now a get(predicate, default) method. 2002/11/21 RELEASE 1.1.2 Fixed Literal's __eq__ method so that Literal('foo')=='foo' etc. Fixed Resource's __setitem__ method so that it does not raise a dictionary changed size while iterating exception. 2002/11/09 RELEASE 1.1.1 Resource is now a special kind of URIRef Resource's __getitem__ now looks at rdfs:range to determine return type in default case. 2002/11/05 RELEASE 1.1.0 # A new development branch Cleaned up interface and promoted it to SIR: Simple Interface for RDF. Updated parser to use SAX2 interfaces instead of using expat directly. Added BTreeTripleStore, a ZODB BTree TripleStore backend. And a default pre-mixed TripleStore that uses it. Synced with latest (Editor's draft) RDF/XML spec. Added datatype support. Cleaned up interfaces for load/parse: removed generate_path from loadsave andrenamed parse_URI to parse. 2002/10/08 RELEASE 0.9.6 # The end of a development brant BNode can now be created with specified value. Literal now has a language attribute. Parser now creates Literals with language attribute set appropriately as determined by xml:lang attributes. TODO: Serializer-Literals-language attribute TODO: Change __eq__ so that Literal("foo")=="foo" etc TripleStores now support "in" operator. For example: if (s, p, o) in store: print "Found ", s, p, o Added APIs/object for working at level of a Resource. NOTE: This functionality is still experimental Consecutive Collections now parse correctly. 2002/08/06 RELEASE 0.9.5 Added support for rdf:parseType="Collection" Added items generator for getting items in a Collection Renamed rdflib.triple_store to rdflib.TripleStore to better follow python style conventions. Added an Identifier Class Moved each node into its own Python module. Added rdflib.util with a first and uniq function. Added a little more to example.py Removed generate_uri since we have BNodes now. 2002/07/29 RELEASE 0.9.4 Added support for proposed rdf:nodeID to both the parser and serializer. Reimplemented serializer which now nests things where possible. Added partial support for XML Literal parseTypes. 2002/07/16 RELEASE 0.9.3 Fixed bug where bNodes where being created for nested property elements when they where not supposed to be. Added lax mode that will convert rdf/xml files that contain bare IDs etc. Also, lax mode will only report parse errors instead of raising exceptions. Added missing check for valid attribute names in the case of production 5.18 of latest WD spec. 2002/07/05 RELEASE 0.9.2 Added missing constants for SUBPROPERTYOF, ISDEFINEDBY. Added test case for running all of the rdf/xml test cases. Reimplemented rdf/xml parser to conform to latest WD. 2002/06/10 RELEASE 0.9.1 There is now a remove and a remove_triples (no more overloaded remove). Layer 2 has been merged with layer 1 since there is no longer a need for them to be separate layers. The generate_uri method has moved to LoadSave since triple stores do not have a notion of a uri. [Also, with proper bNode support on its way the need for a generate_uri might not be as high.] Fixed bug in node's n3 function: URI -> URIRef. Replaced string based exceptions with class based exceptions. Added PyUnit TestCase for parser.py Added N-Triples parser. Added __len__ and __eq__ methods to store interface. 2002/06/04 RELEASE 0.9.0 Initial release after being split from redfootlib.
