Today, we released DBpedia 3.1. As always in the past years, the size of Wikipedia increased a lot over the past months. The new extraction contains 116,7 million triples, marking an increase of 27% over the previous version. The OpenLink team and the research group around Chris Bizer helped us to produce the release.

Apart from the more recent Wikipedia dumps we used, some notable improvements are a much better YAGO mapping, providing a more complete (more classes assigned to instances) and accurate (95% accuracy) class hierarchy for DBpedia. The Geo extractor code has been improved and is now run for all 14 languages. URI validation has switched to the PEAR validation class.

We just released version 0.4 of the Triplify script. After the initial release several months ago we made quite some additions and bug fixes the most important of which are:

• Update log functionality added - allows Semantic Web crawlers to get incremental updates, see http://triplify.org/vocabulary/update
• linked data publication now also works without Apache’s mod_rewrite
• Syntax for indicating objectProperties added, e.g.:SELECT id,user_id 'sioc:has_creator->user'
• Additional metadata can now be added via $triplify[’metadata’]
• The configuration variable $triplify[’CallbackFunctions’] allows programmatic post processing of DB content

Thanks to everybody contributing bug fixes or comments (especially Sebastian Hellmann, Danh Le Phuoc, Rolf Strathewerd, Elias Theodorou).

The AKSW research group is pleased to announce that OntoWiki 0.8.5 is now available for download. Changes in this release include

• A plug-in and event architecture
• A file / document manager
• Rest webservices for login / query / export databases
• WebDAV support for browsing and exporting resources
• A new JSON exporter that uses the RDF JSON specification draft from talis
• New Plugins: Semantic Sitemap and Container Manager

as well as a bunch of bug fixes.

The project development site moved from SourceForge to GoogleCode. We have also created two new mailing lists as google groups for user support and development issues. The issue tracker moved a few weeks ago in order to prepare the release (see Goodbye SourceForge …).

Many thanks to the main contributors of this OntoWiki release: Norman Heino, Philipp Frischmuth, Christoph Rieß and Julian Jöris as well as Michael Haschke and Maria Moritz!

We just release a new version of our Web application plugin Triplify, which exposes structured data from relational databases as Linked Date, RDF, and JSON. This release contains a number of bugfixes and impovements. Most notable the compatibility with PHP4 was improved and the possibility to add meta-data to your RDF added.

These are the changes in V0.3 (08-04-2008):
* added owl:imports statement importing the vocabulary
* added rdfs:comment about generator
* configuration variable “register” added
* Syntax for indicating objectProperties added:
SELECT id,user_id ’sioc:has_creator->user’
* Configuration variable $triplify[’cachedir’] added
* proper UTF8 encoding of literals added (thanks to Rolf Strathewerd)
* Configuration variable $triplify[’license’] added
* Configuration variable $triplify[’LinkedDataDepth’] added
* Configuration variable $triplify[’metadata’] added
* Configuration variable $triplify[’CallbackFunctions’] added

After a first preview release a couple of weeks ago we worked hard to prepare a first public release of Triplify. We fixed a number of bugs and added several additional features, some example configurations for popular Web applications were created and the Web site was completely overhauled: Michael Haschke created the new Triplify logo as well as the design and most other visuals on the site. For those who missed the first Triplify announcement:

Triplify enables the effortless “semantification” of Web applications. Triplify is a small plugin for Web applications, which reveals the semantic structures encoded in relational databases by making database content available as RDF, JSON or Linked Data.

Triplify is very light weight: It consists just of few files with less than 500 lines of code. For a typical Web application a configuration for Triplify can be created in less than one hour and if this Web application is deployed multiple times (as most open-source Web applications are) the configuration can be reused without modifications.

Triplify makes Web applications easier mashable and lays the foundation for next generation, semantics based Web searches.

More infos, the software release, some example configurations for OpenConf, Open Journal Systems, WackoWiki, WordPress and Drupal are available from: http://triplify.org
