Due to current rumour that appears on the net and in chats around me because of my talk on wednesday at ISWC: gnowsis is not part of KDE. But nepomuk-kde is part of kde.

its all a bit complex: gnowsis was my diploma thesis and was continued as open source project at DFKI, where I started working in 2004. In 2006, NEPOMUK started as a EU project (hence NEPOMUK was then used as project name for an EU research project, not for software) which funded research on Semantic Desktop. Gnowsis continued a bit until about December 2006, when we reached version 0.9.2, which is the last release.

Since then, most of our energy goes into dev.nepomuk.semanticdesktop.org ("Psew", nepomuk-server) which is a Java-based Semantic Desktop research prototype, and much work also goes into nepomuk.kde.org, which is a KDE based semantic desktop product.

nepomuk-KDE = product
gnowsis = Leo's hibernating Semantic Desktop open source project
nepomuk-server = java based semantic desktop research prototype (=most many features, but less inteagration with os as KDE has)
psew = GUI for nepomuk-server (at the moment also bundles nepomuk-server)

All of them share the same concepts: RDF on the desktop, a PersonalInformationModel, Annotation of everyday things, embedding into existing applications (=thats where we differ from others like haystack).

but as people keep asking about it: I do long for a working semantic desktop, and porting gnowsis' simplicity to KDE would indeed be nice.
How nice? Nice enough that you want to pay me something to do it?

Because I would like to continue working on this the next years (NEPOMUK EU project or not) .... the first six years were already quite rewarding :-)

ANNOUNCEMENT OF Aperture 1.2.0 RELEASE

Aperture is a Java framework for extracting full-text content and
metadata from various information systems (e.g. file systems, web sites,
mail boxes) and the file formats (e.g. documents, images) occurring in
these systems.

Homepage:
http://aperture.sourceforge.net/

Download URL:
https://sourceforge.net/project/showfiles.php?group_id=150969&package_id=166878&release_id=636375

After three years of development Aperture is stable enough
to drop the .beta suffix from the release. 1.2.0 leverages
architectural improvements made in 1.1.0.beta to bring
support for compressed archives and to streamline
email processing. A completely new service - the
DataSourceDetector allows applications to provide
suggestions to users about the data sources on their
desktops. A host of bugfixes and minor improvements rounds
the image of the leanest and meanest version of Aperture
ever made. Enjoy.

What's new?

• a completely new Aperture service - the
  DataSourceDetectors - can be used to provide advice to
  the user about the data sources on the desktop
• new subcrawlers for .zip, .gzip, tar and bzip2 compressed
  files
• unification of the email handling - now the ImapCrawler,
  MboxCrawler and the MimeSubCrawler use the same code in
  the DataObjectFactory to convert emails to RDF. The
  MimeExtractor has been deprecated, switch to
  MimeSubCrawler
• some bugfixes in the email handling code, plain text, and
  xml attachments are treated correctly, threads are
  reflected in the resulting rdf
• the pdf extractor has some basic support for XMP metadata
  (thanks to JempBox)
• a completely new XmlSafetyUtil class that helps to deal
  with characters that are valid in RDF, but invalid in XML
  thus breaking the serialization
• the uris of subcrawled resources follow the pattern
  established by the Apache Commons VFS project.
• new Sesame 2.2.1 bundled with Aperture features dramatic
  performance optimizations, e.g. the aperture test suite
  is 2 times faster, this may also be a boost for your
  application
