[Sep 19 2009]
* ADDED: Turtle write library.
[Sep 9 2009]
* MODIFIED: rdf_load/2 no longer shares blank nodes by default. This is
not allowed according to the standards.
[Sep 1 2009]
* ADDED: First version of low-level primitives for faster Turtle support
* CLEANUP: make RDF library depend on new iri_xml_namespace/3.
[Aug 31 2009]
* ADDED: rdf_graph_prefixes/3 and realised various enhancements
[Aug 26 2009]
* FIXED: rdf_graph_prefixes/2 to return all namespaces instead of only those
that have ns/2 declarations (as the title suggests).
[Aug 24 2009]
* MODIFIED: RDF hook no longer accepts text/html explicitely
[Aug 21 2009]
* FIXED: Turtle parser to deal with files where the last line is a
non-terminated comment. Ivo Swartjes
[Aug 20 2009]
* ADDED: Library semweb/rdf_compare for comparing RDF graphs (mostly used by
RDF test libraries)
* ADDED: Process the text/turtle MIME-type
* ADDED: Turtle parser to support booleans (true and false)
[Aug 19 2009]
* MODIFIED: rdf_process_turtle/3 prints messages instead of aborting after
the first error. Also some progress to enhance the error messages.
* ADDED: rdf_current_ns/2 as a replacement for rdf_db:ns/2 and rdf_graph_prefixes/2
to query prefixes used in a specific graph.
[Jul 31 2009]
* FIXED: rdf_load/1 failed after unloading the data using rdf_unload/1. Willem Robert van Hage.
[Jul 30 2009]
* CLEANUP: Modernise rdf.pl and rdf_db.pl module handling.
[Jul 24 2009]
* MODIFIED: rdf_load_turtle/3 now returns IRIs instead of URIs.
[Jul 21 2009]
* MODIFIED: Make initialization/1 ISO compliant
This patch is a modest cleanup to the implementation of '$load_file'/3
from init.pl and provides an ISO compatible implementation of
initialization/1. This executes the argument goal *after* loading the
file rather than when encountering the directive. Often this makes no
difference, but notably load_foreign_library/1 is an exception.
Therefore we added use_foreign_library/1,2 that act as a directive and
provides proper integration with saved-states automatically. Loading
code using initialization(load_foreign_library(...)) will load the
library immediately and issue a warning.
See initialization/1,2 for details and further hints for dealing with
possible compatibility problems.
[Jul 19 2009]
* FIXED: RDF Literal indexing messed up handling of 'false'. Vera Hollink.
[Jun 28 2009]
* FIXED: RDF literal matches (literal(exact(string), X))
[Jun 22 2009]
* ADDED: Efficient SPARQL compliant literal matching to RDF-DB
[Jun 19 2009]
* FIXED: Semweb: writing RDF/XML should not use bnodes as typed nodes. Chris Mungall.
[Jun 17 2009]
* FIXED: Turtle UTF-8 handling
* FIXED: rdf_load/2: Do not record a file as loaded before completion.
* ADDED: Semweb: Register turtle parser for .n3 files
[Jun 16 2009]
* FIXED: Pass Turtle test-case #10.
[May 31 2009]
* FIXED: RDF Transaction logging in persistency layer. Jacco van Ossenbruggen.
[Mar 19 2009]
* CLEANUP: Removed all trailing whitespace from all source-files. This avoids many GIT (merge) warnings.
[Mar 12 2009]
* MODIFIED: Renamed concat_atom/2,3 into atomic_list_concat/2,3 for compatibility. Moved the old predicates into library(backcomp). It is adviced to update your code, but 99% of the code will remain working because the old definitions are autoloaded.
[Mar 5 2009]
* FIXED: ensure the local part after splitting a URI is a valid XML name
* MODIFIED: Use graph(URI) instead of db(URI) for specifying the RDF graph that must be saved. db(URI) is still supported for backward compatibility.
[Jan 21 2009]
* FIXED: RDF writer: write valid XML if the namespace entity contains characters
that must be %-escaped. Jacopo Urbani.
[Jan 13 2009]
* FIXED: RDF/XML could save illegal XML if multiple namespaces are used
for predicates where one namespace is a prefix of another one. Jacopo Urbani.
[Dec 19 2008]
* ADDED: Allow for stream(Stream) as target in rdf_save/2
[Oct 8 2008]
* MODIFIED: rdf_load/[1,2] now raises an existence_error if the input does not exist.
* CLEANUP: Generalise plugin interface to deal with different storage envelopes in rdf_load/2.
[Sep 23 2008]
* ADDED: Preserve the modification time of the source URL in binary RDF files.
[Sep 11 2008]
* PORT: Add AC_PREREQ to configure.h for systems that auto-select autoconf
versions. After tip by Ulrich Neumerkel.
[Aug 11 2008]
* INSTALL: Remove all configure files from the git repository
[May 20 2008]
* FIXED: %-escape [] when transforming URI to URL.
[May 5 2008]
* FIXED: rdf_quote_uri/3 not to map & to %26. Jacco van Ossenbruggen
[Apr 27 2008]
* FIXED: RDF-DB: predicate hash error that caused most predicates to be
hashed on the same key. Fixes slow rdf_save/2 reported by Jacco van
Ossenbruggen. Should also positively effect determinism and reliability
of rdf_estimate_complexity/4.
[Apr 26 2008]
* DOC: Fixed some paths in semweb documentation. Jacco van Ossenbruggen
[Apr 18 2008]
* MODIFIED: Renamed hash_term/2 to term_hash/2. Added hash_term/2 to
library(backcomp), so most code should not notice this.
[Apr 17 2008]
* FIXED: Avoid deadlock in RDF literal index when removing a literal
[Apr 14 2008]
* CLEANUP: Remove calls to sformat from system libraries (backward compatibility)
[Apr 11 2008]
* ENHANCED: rdf_litindex.pl: 40% faster building of the literal token database
[Apr 10 2008]
* PERFORMANCE: RDF-DB: speedup literal hash handling
[Mar 26 2008]
* ENHANCED: make rdfs_individual_of(+,+) semidet.
[Mar 5 2008]
* FIXED: determinism detection in rdf_reachable/3
[Feb 18 2008]
* MODIFIED: Stricter checking in rdf_global_id/2 and rdf_global_term/2
[Jan 23 2008]
* PORT: Bug#346: Allow overriding COFLAGS and CWFLAGS in package
configuration. Keri Harris.
[Dec 17 2007]
* FIXED: Possible missing match on subproperties in rdf_has. Jacco van Ossenbruggen and Michiel Hildebrand
[Dec 13 2007]
* FIXED: Bug#332: operator declarations could mess up RDF/XML output. Chris Sutton
and Yves Raimond.
[Nov 28 2007]
* FIXED: rdf_persistency.pl now keeps track of sources
[Nov 14 2007]
* FIXED: RDF HTTP plugin to request application/rdf+xml. Yves Raimond.
[Nov 11 2007]
* ADDED: Allow deleting an inverse_of predicate property
[Nov 8 2007]
* ENHANCED: Minimise the time we keep a lock in rdf_load_db/1 to exploit
concurrency.
* ADDED: silent(brief) option value to rdf_attach_db/2. Avoid some file-system
tests to speedup loading many named graphs.
* ENHANCED: Speedup for rdf_retractall(_,_,_,DB) for empty or non-extenting
databases.
* ENHANCED: Avoid quadratic effect when loading many graphs from many
