Update to 1.7.2 - from Jaap Boender

1.7.2                           31-March-2012
---------------------------------------------
- Fix and optimize searching via Nepomuk.

1.7.1                           03-March-2012
---------------------------------------------
- Don't truncate SPARQL queries in virtual collections.
- Optimize change notifications for deleted collection attributes.
- Fix possible data loss during item copy/move operations.
Update to 2.8.0 - from Jaap Boender

2.8.0
 * Improved NRLModel query prefix expansion.
 * Support for plain SQL queries in the Virtuoso backend.
 * Introduced new query language flag QueryLanguageSparqlNoInference.
   This language is not supported by any backends. It is supposed to
   be used in clients like Nepomuk to avoid the usage of long user
   types which are harder to read.
 * Convert Virtuoso IRI_ID values into simple literal strings. At some
   point if the need arises we might call ID_TO_IRI() to convert them
   into URIs.
 * New boolean option "noStatementSignals" in the Virtuoso backend which
   will disable Model::statementsAdded() and friends.
 * Improved local unix socket communication in the server/client system:
   A custom socket implementation as a replacment for QLocalSocket makes
   it possible to use one socket across threads.

2.7.6
 * Support for the new SPARQL 1.1 DELETE statement which omits the graph
   to delete from for faster removeAllStatement execution.
 * Support for the new default graph query result format of Virtuoso >= 6.1.5
 * Fixed apidox generation with Doxygen 1.8.0.

2.7.5
 * Be less strict when converting a string to a QDateTime:
   - Allow an empty time part, ie. "2011-10-04".
   - Allow the usage of a space instead of "T" to separate date from time.
 * Fixed URI parsing in the SparqlModel.
 * Fixed an endless loop in the VirtuosoModel destruction which can happen
   in rare error cases.
 * Fixed serialization of non-string literal values.
 * Support Turtle result encoding in the SPARQL model.
Update to 0.7.7  - based on patches from Jaap Boender

0.7.7 (2011-12-07)
 - Many nepomuk field name fixes
 - More accurate file format check for tar files
 - Better checking of bounds in OLE files.
 - Increase performance of default file input stream.
 - Check for surrogate pairs in UTF-8 strings.
 - Improve ID3 analyzer: skip zero padding before mp3 stream to
   handle typical LAME output, implement unsynchronization flag handling
 - Properly finish child indexing in all analyzers.
0.7.6 (2011-07-26)
 - Fix build with clucene 2.3
 - Use the deprecated function av_metadata_get for libffmpeg
 - Improved child indexing
 - Convert the DateTime field in EXIF data to a time_t value.
 - Move DigestEventAnalyzer to a plugin.
0.7.5
 - Synchronize the modules. In 0.7.4, the modules were not synchronized.
0.7.4
 - Disable building strigidaemon and strigiclient on windows
 - Support more feature of Strigi Query in the CLucene backend.
 - Fix premature EOF condition in PDF parser.
 - Make discovering of invalid characters in checkHeader more compliant
   to RFC822.
 - Improvements to movie analysers that use ffmpeg.
 - Fix a bug where width and height of certain JPG files are not shown.
 - Fixes to libstreams to avoid crashes.
 - Improved Nepomuk compliance.
 - Faster reading of streams with SkippingFileInputStream and
   MMapFileInputStream.
 - Reorganize Strigi into smaller modules.
0.7.2
 - Improve cpp analyzer speed and output
 - Fix crash due to deep nesting of calls in pdf analyzer
 - Fix iconv use on Mac OS X
0.7.1
 - Support more fields from ODF documents
 - Improved skipping behavior on streams for large files.
 - Added album art support.
 - Added support for ID3v1 tags.
 - Added MP3 stream metadata extraction, UTF-16 support in tags.
 - Extended the range of metadata extracted by ID3 analyzer.
 - Added a FLAC audio file analyzer.
 - Significantly unbreak the PDF analyzer.
 - Fix scanning trees where permissions are insufficient to read some parts
 - Check for multithreaded version of libxml2
 - Require newer CLucene version (0.9.21)
0.7.0
 - Change to Nepomuk ontologies
 - Set file property for embedded ar streams. This fixes the opening
   of these streams in archivereader.
 - Instead of reading each .rdf file at once in memory and then parse
   it, use the libxml2 I/O API to read chunks of the file when requested.
 - The attribute value is not '\0' terminated but has a pointer to the
   end of the string. In addition, string comparison was sped up by
   first comparing the string length.
0.6.5
 - Fix KDE bug 185551: Strigi now allows paths that start with protocol:/*
   like 'file:///' or 'remote:/'
 - Add a new function AnalysisResult::child(). This function allows an
   AnalysisResult instance to access the last child it has had indexed.
   This is needed for cases when a parent knows something about a child
   which the child does not know. In such cases the parent can call
   child()->addValue(...).
 - Adjust to the new library naming scheme in iconv-1.12
 - Implemented missing addTriplet method
 - Rewrite the implementation of ArchiveReader. The new implementation
   is more efficient in listing contents of directories. Now single
   directory entries can be returned without the need for reading the
   entire archive of which the directory is a part.
