최근에 웹 기술은 PC를 념어 휴대폰, PDA, 정보가전, 로봇 등 모든 디바이스로 적용이 확대되고 있으며, 웹에 대한 국제 표준을 주도하고 있는 W3C(World Wide Web Consortium)는 2007년 상반기에 유비쿼터스 웹 응용을 위한 표준 개발을 시작하였다. 이를 담당하고 있는 유비쿼터스 웹 응용 워킹그룹은 탁상용 컴퓨터뿐 아니라 사무용품, 가정 매체 기구, 이동 전화, RFID나 바코드를 포함하는 센서나 이펙터(effector) 등의 유비쿼터스 디바이스들이 다양하게 흩어져 있는 환경에서 쉽게 웹 응용 개발을 가능하게 하는 표준 개발을 목표로 한다. 본 워킹그룹의 활동은 크게 가지로 나누어 볼 수 있다. 첫 번째는 디바이스 독립 워킹그룹(Device Independence Working Group)의 활동이 종료됨에 따라 이 워킹그룹에서 완성하지 못한 표준들을 이어받아 마무리 하는 활동이다. 두 번째는 리모트 이벤팅(remote eventing), 디바이스 코디네이션(device coordination) 그리고 의향 기반 이벤트(intent-based events) 등 유비쿼터스 웹 응용을 위해 펼요한 새로운 표준 개발을 하는 것이다. 본 논문에서는 최근에 W3C에 서 추진되고 있는 유비쿼터스 웹에 대한 표준화 동향을 설명한다.
