Over the last few years, the EC GI & GIS Workshop has focused on the development of a European Spatial Data Infrastructure (ESDI) reviewing work in progress (Dublin 2002), user needs (Coruna, 2003), and the state of the art (Warsaw, 2004). The adoption by the European Commission of the INSPIRE proposed Directive in July 2004, and the publication of the INSPIRE Workprogramme 2005-06 in February 2005 mark a major step forward in the development of the ESDI. Hence this year's choice of theme: ESDI: Setting the Framework.

• Review the current state of progress of the draft legislation,
• Offer an opportunity to the Spatial Data Interest Communities to express their needs and improve their understanding of how best to participate in the drafting of the INSPIRE implementing Rules,
• Further our understanding of the implementation challenges, costs, and benefits of SDIs at national, regional, and local level
• Identify key research issues that need addressing by the GI community to support the implementation of ESDIs.

The Workshop will be organised through a series of plenary sessions addressing common policy issues, and parallel sessions focusing in particular on applications / implementations of SDIs, and research issues.

Short papers or posters addressing SDI applications and implementation experiences at national, regional or local level. We are particularly interested in candid accounts of what works, and what does not work, what are perceived benefits for policy, public administration, citizens, and the private sector. Proposed submissions must clearly indicate whether they are for a poster or a short presentation (15 min. max) and be no longer 500 words, with emphasis on the results achieved. Proposals will be evaluated by the programme committee and those accepted will be include in the Conference proceedings (in CD-ROM and online)

Longer papers and presentations (20 min max) addressing in particular SDI research issues relating to data, technology, interoperability, people, organisational implementation, and socio-economic impacts of SDIs. These submission will have a strong research orientation, and proposals will be of 1500 words with references. Proposals will be evaluated by an International Scientific Committee and for those accepted, full paper submissions (5000-7000 words) will be considered for a full peer reviewed special issue of the Journal of Geographic Systems
