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.

The entire Aperture Framework has been rewritten to utilize the RDF2Go framework.
It is now completely independent from the underlying RDF store. Aperture registries
and factories can now be used in an OSGi environment as services. The
infrastructure allows for on-the-fly deployment of new extraction components.

Additional improvements include:

- the logging subsystem has been changed from Java Util Logging to SLF4J. This solves
some classloading issues that were encountered when using Aperture in
web applications.

- a set of OSGI BundleActivators have been added for embedding Aperture
in an OSGi environment. Additional ant target creates two OSGI bundles from
Aperture source code. The OSGi setup has been tested extensively
in the Nepomuk Social Semantic Desktop project.

Updated dependencies
- updated Sesame 2.0 from alpha-3 to beta-4
- updated the applewrapper library to version 0.2
- RDF2Go 4.4.1
- Sesame 2.0-beta4 RDF2Go Adapter revision 2682
- SLF4J 1.3.0
- osgi.core-4.0.jar - The reference OSGI jar file, necessary to compile activators.
- don't use apache commons-logging anymore, the RDF2Go depends on commons-logging
but this is now done with the jcl104-over-slf4j bridge
- removed the original commons-codec.jar and replaced with an OSGI-friendly
bundle org.apache.commons.codec_1.2.0.jar
- org.apache.httpclient_3.0.0.rc2.jar

When developing rich client applications for the semantic web, components for visualising and editing RDF data are useful.

The gnogno framework is an approach to bind RDF models from RDF2Go to Swing and Eclipse SWT widgets. It allows to edit text values, make lists, and program user interfaces using a clear design pattern. The RDF data can be taken from various frameworks, such as Jena or Sesame (RDF2Go wraps these). Inspiration for this project comes from the Borland DataSet components, part of Delphi.

I made a 20 minute screencast showing some basic components



At the moment, gnogno is alpha and subject to change, but I would like to hear feedback from you about the principal idea, and if you want to use this project, you may want to join me developing it. Its free software/open source. Please add comments with feedback here to this blog-post.

Why did I do this? I was a professional Delphi programmer before I did Java and Semantic Web, therefore I dig these simple frameworks that bind data directly to the gui.
