OntoWiki 0.9.5 Available

Posted on June 14, 2010 by Sebastian Tramp

The AKSW research group is pleased to announce that OntoWiki 0.9.5 is now available for download.

OntoWiki is a web-application enabling the collaborative creation and (linked data) publication of RDF knowledge bases.

More information about OntoWiki can be found at http://ontowiki.net. You can download OntoWiki in our google code file section.

Enhancements in this release include:

  • Support for Semantic Pingback, a protocol which enables OntoWiki to communicate named links from linked data resources or blog systems like WordPress.
  • Support for the publication of provenance information via Linked Data.
  • A new navigation module which support the configuration and usage of arbitrary navigation hierarchies (e.g. based on classes, SKOS elements, geospatial entities or FOAF groups).
  • A bookmarklet for collecting RDFa-based information into a specific OntoWiki knowledge base.
  • More editing widgets, e.g. for phone number and mailto: resources.
  • A new mapping module for the resource visualisation and filtering based on maps.
  • Attribute / Tag clouds based on selected RDF properties.
  • A GUI for complex SPARQL filter (contains, larger, smaller, between and bound)
  • A JSON/RPC server as an additional interface (e.g. for the command line client)
  • A plugin to create nice URIs based on the content of a new resource.

A detailed log of the over 200 enhancements and bug fixes of this release is available at our issue tracker.

Many thanks to the contributors of this OntoWiki release (in alphabetical order): Atanas Alexandrov, Christian Maier, Christoph Riess, Jonas Brekle, Marvin Frommhold, Michael Haschke, Michael Martin, Michael Niederstätter, Natanael Arndt, Norman Heino, Philipp Frischmuth and Tim Ermilov

best regards

AKSW at ESWC

Posted on June 2, 2010 by Sören Auer

Extended Semantic Web Conference started yesterday in Hersonissos, Crete. AKSW is involved in this years ESWC in various ways: We co-organized the 6th Workshop on Scripting and Development (SFSW10) probably for the last time this year at ESWC, since the original aim of promoting more light-weight, pragmatic semantic web applications of the SFSW workshop series became now rather mainstream. Sören was one of the panelists of the panel on “Linked Data: Now what?”. With the two papers “LESS – Template-Based Syndication and Presentation of Linked Data” and “Improving the Performance of Semantic Web Applications with SPARQL Query Result Caching” AKSW is also well represented in the main scientific conference programme.

Nachtrag: 2. Leipziger Semantic Web Tag

Posted on May 11, 2010 by Sebastian Tramp

Am letzten Donnerstag fand mit großem Erfolg der 2. LSWT auf dem Mediencampus in Leipzig statt. Die Veranstaltung zog über 200 Teilnehmer aus Wissenschaft, Unternehmen und öffentlichen Verwaltungen an. In vielen interessanten und anwendungsorientierten Vorträgen konnten die Besucher Einblicke in semantische Technologien erhalten sowie deren vielfältigen Umsetzungen in Unternehmen und Verwaltungen kennen lernen.

Aussteller boten ferner die Möglichkeit zum direkten Erfahrungsaustausch. Hier konnte der Besucher semantische Technologien an praktischen Beispielen selbst testen und diskutieren.

Ein besonderer Höhepunkt der Veranstaltung stellte die Gründung des deutschen Zweiges der Open Knowledge Foundation dar. Die gemeinnützige Organisation setzt sich vor allem für den offenen Zugang zu Daten ein.

Lebendige Eindrücke vom 2. LSWT fängt unser Video ein..

Die Präsentationen zu den einzelnen Vorträgen stehen auf der LSWT 2010 Webseite zur Verfügung.

Semantic Web Journal launched

Posted on April 25, 2010 by Sören Auer

A short while ago the Semantic Web Journal was launched. Pascal Hitzler and Krzysztof Janowicz are editors-in-chief and AKSW’s Sören Auer serves on the editorial board. The journal published by IOS Press differs from other journals, in particular, since it follows an open and transparent peer-review process, which engages a wider community besides expert reviews. Supported by its young and agile editorial board, the SWJ can be expected to bring a lot of fresh wind to an already aging Semantic Web community. Since SWJ just started, it is right now a perfect time to submit an article to SWJ or propose a special issue. Please check out: http://www.semantic-web-journal.net.

GoodRelations and LESS

Posted on April 21, 2010 by Sören Auer

Martin Hepp just published a short tutorial on using the GoodRelations vocabulary for product, price, and company data together with LESS. Martin explains, how a public SPARQL endpoint holding GoodRelations data can be accessed and results displayed using LESS. The tutorial is available at:

Dedicated Virtual LinkedGeoData Server

Posted on April 15, 2010 by Jens Lehmann

Due to the rising interest in our LinkedGeoData project and the growth of the underlying OpenStreetMap database, we expanded the AKSW server infrastructure. LinkedGeoData will gradually move to a new server running Debian within the next weeks. This server runs on a virtual machine inside a new cluster at the University of Leipzig. Resources (memory, CPU, hard disk) can be allocated dynamically (of course limited by financial restrictions) such that we hope to keep up with the growth of the project. The first LinkedGeoData applications to move on the new server will be the Linked Data interface and the LGD Browser.

Linked Opend Data Project of the Faculty of Mathematics and Computer Science at Leipzig University

Posted on April 9, 2010 by ThomasRiechert

From this summer term onwards the Faculty of Mathematics and Computer Science at Leipzig University provides structured information about academia such aslectures, tutors, rooms and timetables as Linked Open Data. The platform http://od.fmi.uni-leipzig.de, which is based on the OntoWiki framework, provides a vocabulary and an ontology. Apart from the possibility of the direct linking of resources in the semantic web, this platformn offers a SPARQL endpoint. The accessible information provides a basis for the integration into E-Learning platforms or personal knowledge management applications.

LinkedGeoData Google Code Project Started

Posted on March 24, 2010 by Jens Lehmann

We decided to open source the code for the LinkedGeoData project and move it to Google Code:
http://code.google.com/p/linkedgeodata/

Initially, we will migrate the Triplify code, the LinkedGeoData browser, and the DBpedia mapping code into the repository. Naturally, it will take a while for the migrated code base to work as expected.

We will use the issue tracker as a central means for organising code enhancements. If you find bugs or have feature requests, please add them: http://code.google.com/p/linkedgeodata/issues/list
