2. > Bowstreet Founded in 1998 HQ in Portsmouth, NH 150+ employees Web Services Platform Company Bowstreet provides a web services development and assembly platform that automates the creation and maintenance of complex web applications

3. > What we’ve heard (too!)… Customers want to integrate services into composite applications With control over Presentation With “correct” responses to user interaction Business Needs: Embedding: Syndication and Co-branding Device Independence Portal or Composite Web App Container administration User profiling

4. > What we’ve experienced… Issues in composite portals: link bending style sheets Java script single signon Session/state maintenance Issues in composite apps: single signon transaction control service flow

5. > Thoughts on markup Web Service markup Services should be device independent Services should be markup neutral Simplifying protocol around link bending and actions (WSUI, XForms)

6. > Remote container? Remote container rather than direct interaction with web service? Might alleviate every web service from: life cycle semantics transactional semantics (BTP tie-in?) Cleaner handoff to app servers?

7. > Security and transaction support? Provide hooks BTP
