<title>Raptor RDF Parser Toolkit - To Do List</title>
</head>
<body>
<h1 style="text-align:center">Raptor RDF Parser Toolkit - To Do List</h1>
<h2>Bugs and Features</h2>
<ul>
<li>Update the rdf/rdfs schema documents. Convert the turtle labels
from unicode character form into UTF-8 (DATA, DOCS)</li>
<li>LSID URN support (FEATURE)</li>
<li>Ensure there is support to allow
<a href="http://librdf.org/rasqal/">Rasqal</a>
to register a parser outside raptor that provides RDF query results as
triples. Alternatively, provide a skeleton wrapper parser that
allows the same by delegating all triple generation to callbacks. (FEATURE)</li>
<li>Add a guessing parser that sends an Accept: HTTP header for all
supported mime types and uses the returned headers to select a
parser. (FEATURE)</li>
<li>Describe in libraptor.3 relevant raptor.h structures -
describe important ones such as raptor_statement, raptor_locator and
raptor_feature as well as reference internal ones such as raptor_identifier,
raptor_identifier_type, raptor_uri_source, raptor_ntriples_term_type,
raptor_genid_type and raptor_uri_handler for the raptor_uri class.
(DOCS)</li>
<li>RSS tag soup parser junks/overwrites element content if it is
delivered in chunks rather than as one big CDATA, such as when
libxml2 sees entities, it emits the content in bits (BUG)</li>
<li>Add a gzip2/bzip2 content reading interface, using libxml2 to do the hard work (FEATURE)</li>
<li>Turtle parser: the lexer <code>lval->string</code> values get overwritten on errors (BUG)</li>
<li>Record the xml parser used and make available from API (FEATURE)</li>
<li>Add a N3 parser (FEATURE)</li>
<li>Add an XSLT 'parser' based on <a href="http://xmlsoft.org/XSLT/">libxslt</a> (FEATURE)</li>
<li>Provide a perl interface (FEATURE)</li>
<li>Add namespace/prefix declaration user level callback (FEATURE)</li>
<li>Other <code>rdf:parseType</code> support (FEATURE)</li>
<li>Add a PNG parser, like
<a href="http://pmt.sourceforge.net/pngmeta/">pngmeta</a> and parse
the embedded RDF/XML into triples (FEATURE)</li>
</ul>
<h2>Done</h2>
<p>The most recent changes are at the top, with the first
release version where appropriate.</p>
<ul>
<li>Allow the supported parsers to be selected by configure (1.3.3)</li>
<li>Errors which happened when fetching WWW content were always
printed to stderr. They are now passed to the main error routines
which allows applications to retrieve them. (1.3.2)</li>
<li>In lax mode, warns when unknown rdf:parseType values are seen to prevent
things like 'owl:collection' and 'collection' passing through (1.3.1)</li>
<li>Turtle parser: a bare ':' and qnames such as 'rdf:_1' now work (1.3.1)</li>
<li>Describe in libraptor.3 the use of UTF-8 for strings and URIs. (1.3.1)</li>
<li>Send an HTTP Accept: header with WWW requests corresponding to the
mime type of the parser selected, accepting all others at lower q (1.3.0)</li>
<li>Guess parser from a mime type, content fragment and/or
content name such as a filename or URI (1.3.0)</li>
<li>Turtle parser: use <code>raptor_generate_id</code> for blank node identifiers (1.3.0)</li>
<li>Added <code>--enable-xml-1-1-names</code> to enable XML 1.1 name checking instead of XML 1.0 (1.1.0)</li>
<li>Updated <a href="http://www.w3.org/TR/xml11/">XML 1.1</a> name checking for ranges in the XML/Namespaces in XML 1.1 proposed recommendations (1.1.0)</li>
<li>Added <code>--disable-nfc-check</code> to disable the NFC linking/checking with GNOME glib, even if that library is present (1.1.0)</li>
<li>Made the N-Triples parser use <code>raptor_generate_id</code> for blank nodes identifiers (1.1.0)</li>
<li>Updated the RDF/XML parser to handle libxml 2.6.0 SAX2 API which
changes the names of all of the SAX1 calls (1.1.0).</li>
<li>Added an <a href="http://www.ilrt.bristol.ac.uk/discovery/2003/11/ntriplesplus/">N-Triples Plus</a> parser (1.1.0)</li>
<li>Correct line counting for N-Triples with \r\n line (DOS) files and
when the line crosses a chunk. (1.1.0)</li>
<li>Handle WIN32 file URIs starting <code>file://c:</code>... (1.1.0)</li>
<li>Scanning (<tt>rapper --scan</tt>) for <tt>rdf:RDF</tt> in embedded XML does not work (0.9.13)</li>
<li>URI retrieval - make sure it chops off the fragment before
fetching. (0.9.12)</li>
<li>Make 'make check' not die if NFC tests fail, possible if
no GNOME glib2 is present. (0.9.12)</li>
<li>Unicode character normalization NFC checks not implemented (0.9.11)</li>
<li>XML (Exclusive) Canonicalization for XML Literals not implemented (0.9.11)</li>
<li>libxml2 currently does not do XML attribute normalization i.e.
removing whitespace around attribute content. Added a fix (0.9.11)</li>
<li>Added raptor_www_no_www_library_init_finish to allow once-only
www library startup/shutdown to be prevented. Default to performed
so that most higher level apps do not need to know or care (0.9.10)</li>
<li>Docs updated for 0.9.7 to 0.9.10 API changes in the <a href="libraptor.html">libraptor.3</a> manual page</li>
<li>Escape XML attribute values in parseType literal content generation (0.9.10)</li>
<li>Passing NULL to raptor_start_parse base URI for rdfxml parser
crashed it. Now the RDF/XML parser fails. (0.9.9)</li>
<li>rdf:parseType="Literal" content with &, <, > and
unicode characters did not get escaped in the encoded string into
entities/character entities. (0.9.9)</li>
<li>XML Namespaces declared with a prefix and no namespace name (URI)
were accepted - this is illegal (0.9.8)</li>
<li>Empty files made rdf/xml parser crash with libxml2 and expat; now both
return failure since an empty doc is not allowed (0.9.8)</li>
<li><tt>rdf:bagID</tt> handling added (0.9.7)</li>
<li>Can now configure on system which has expat alone using
<tt>./configure --with-xml-parser=expat</tt> (0.9.7)</li>
<li>Fix compiling libxml 2.3.5 and nearby versions failing on FreeBSD (which is 20 months old) caused by a change to the xmlSAXHandler structure (0.9.7)</li>
<li><tt>file:</tt> URIs were not correctly handled (0.9.6)</li>
<li>Resilience to XML parser errors, RDF/XML grammar errors (0.9.6)</li>
<li>Manual pages (0.9.6)</li>
<li>Made CDATA section work with libxml (0.9.6)</li>
<li>daml:collection is generating some wrong triples (BUG) (0.9.6)</li>
<li>Compiling on OSX fails on most systems since it requires libtool 1.4.2
or CVS version which requires automake 2.50 and a newer version of
autoconf. This needs significant changes to the autoconfigure
system. See
<a href="http://fink.sourceforge.net/doc/porting/libtool.php">Fink porting libtool to OSX.</a>
The fix for now - <strong>for the packaged sources only, not CVS</strong>
- is to use a patched libtool 1.4.2 (from Debian) that can generate a libtool
that knows OSX. (0.9.6)
</li>
<li>URI resolving to a base URI now working (0.9.5)</li>
<li>Handle <prop:Elt rdf:ID="id" rdf:resource="http://example.org/obj"/> (RDF Core WG syntax change) (0.9.5)</li>
<li>Add xml:base support - RDF Core WG syntax change (0.9.4)</li>
<li>Perform xml:lang processing and pass to application (0.9.4)</li>
<li>parseType literal broken (0.9.4)</li>
<li>Tracking of user IDs/generated IDs available to user code (0.9.3)</li>
<li>daml:collection parseType support (0.9.3)</li>
<li>rdf:li used as a propertyElt does not work (0.9.3)</li>
<li>parseType literal support complete (0.9.3)</li>
<li>Fixed many crashes (0.9.3)</li>
</ul>
<h2>No need to do list</h2>

<li>aboutEachPrefix support - removed from syntax</li>
<li>Special container support - not special anymore, just typed nodes</li>
