The workshop will focus on the challenge of building support for applications. Appropriate themes are:

• architectural issues: naming, location, security, reliability, distribution of functionality (e.g. between client and server), concurrency control, transaction support, multimedia support, scalability, heterogeneity, performance, system monitoring and tuning
• technology and tools for constructing system software: objects, components, events, reflection, dynamic compilation, interpreted languages, authorship and copyright enforcement tools
• engineering issues: requirements capture, component specification and selection, specialisation to meet specific requirements, self-adapting systems, user customization support

Attendance is limited to 60 people, by invitation only. The workshop will be held at the Hotel Tivoli, Sintra, Portugal. Sintra is a small, beautiful village located in the outskirts of Lisbon, chosen by kings and artists as their Summer refuge. The hotel is in the centre of the historical village and is 45 minutes by taxi from Lisbon airport.

Papers will be selected on the basis of ability to foster discussion, originality, and appropriateness to the workshop topic. Accepted papers will be distributed to attendees and via the web. A summary of the workshop will appear in Operating Systems Review. Interested persons should send to the program chair 10 copies of an extended abstract (4 pages maximum) or a uuencoded Postscript file using only standard fonts (e.g. Times). Electronic submissions must print in Europe and the US and last-minute submissions that are unprintable will be rejected; please send an early test sample. The contact person's email and postal addresses should be included on the first page of the abstract. For additional information, see the workshop's web page here.
