Aperture is a Java framework for extracting full-text content and metadata from various information systems (filesystems, Web sites, email inboxes) and the file formats (documents, images) in these systems.
- Aperture has been migrated to use the newly developed Nepomuk Information Element Ontology framework. This added a new level of precision and expressiveness to the output of Aperture components. The ontology itself is endorsed by the Nepomuk Consortium, well documented and maintained.
- The output is now thoroughly tested with an extensible RDF validator for compliance with the ontology. This allowed us to fix a number of bugs that made certain properties appear in places they didn't belong
- The data source configuration API has been overhauled and is now much more easy to use
- A new facility that allows clients to implement dynamic GUIs for data source configuration.
- New JpgExtractor that extracts EXIF annotations from JPG files
- Four new experimental crawlers (Flickr, Bibsonomy, del.icio.us and Apple IPhoto).
- Host of small improvements and bug fixes
Semantic Weltbild 2.0 has more information on the release.
