About the workshop

The W3C OWL Web Ontology Language has been a W3C recommendation since 2004, and specification of its successor OWL 2 is being finalised. OWL plays an important role in an increasing number and range of applications and as experience using the language grows, new ideas for further extending its reach continue to be proposed.

The OWL: Experiences and Direction (OWLED) workshop series is a forum for practitioners in industry and academia, tool developers, and others interested in OWL to describe real and potential applications, to share experience, and to discuss requirements for language extensions and modifications. The workshop will bring users, implementors and researchers together to measure the state of need against the state of the art, and to set an agenda for research and deployment in order to incorporate OWL-based technologies into new applications.

This year's 2009 OWLED workshop will be co-located with the Eighth International Semantic Web Conference (ISWC), and the Third International Conference on Web Reasoning and Rule Systems (RR2009). It will be held in Chantilly, VA, USA on October 23 - 24, 2009. The workshop will concentrate on issues related to the development and W3C standardization of OWL 2, and beyond, but other issues related to OWL are also of interest, particularly those related to the task forces set up at OWLED 2007.

As usual, the workshop will try to encourage participants to work together and will give space for discussions on various topics, to be decided and published at some point in the future. We ask participants to have a look at these topics and the accepted submissions before the workshop, and to prepare single "slides" that can be presented during these discussions. There will also be formal presentation of submissions to the workshop.


Minutes of the Future of OWL session on Friday can be found on the Webont Wiki (thanks to Kendall Clark). Presentation slides are available here
