We are pleased to announce the third alpha release of the Aperture framework.
Aperture is a Java framework for extracting and querying 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.
The most notable feature in this release is a new IcalCrawler. It works with 
iCal files generated by many calendaring applications (Apple iCal, Korganizer, 
Lotus Notes …). It uses a ical-rdf mapping developed by the W3C Rdf 
Calendaring group. Apart from that there are numerous small improvements and 
bugfixes. The tutorial has been expanded with more code examples and UML 
diagrams to facilitate learning for new users.
This the last release before the switch to the RDF2Go framework. 
(The curious can already examine the RDF2Go branch in the cvs).

sorry for the problems, the wiki is truly not ideal.
contact us if you want to do some experiments using gnowsis, or the next version of it: nepomuk.
it sums up to: its an alpha version, a prototype of a beta, which is then a prototype for a product.
