The GCA has posted the Call for Participation for XTech 2008, the largest European XML conference (even if it's not strictly limited to XML any more). "Suggested topic areas include social network platforms, identity management, Ajax, web of data, databases, operations, programming, browsers and mobile devices." This year XTech takes place in Dublin, Ireland from May 6-9. Submissions are due by January 25. It's a nice conference, but I'm not currently planning on attending myself. travel is just becoming too difficult.
