1 NGCWE Expert Group A Reference Architecture for Prof. Juan Quemada NGCWE Expert Group IST Call 5 Preparatory Workshop on CWEs 13th April 2005, Brussels

2 Challenge 1 Priority: very high Availability: medium term -> Long term adaptability to changes Challenge: To agree on a common reference architecture which enables the development of reusable and interoperable service and application components for collaboration at work.

3 Reference Architecture The Reference Architecture achieve interoperation Should precisely define all the elements necessary to achieve interoperation among collaborative tools This includes: functions, protocols, interfaces, … The “upper layer” middleware Implement the reference architecture Facilitate the development of interoperable tools Should be delivered as “open software libraries”

4 Relation to other Recomendations The Reference Architecture should take into account existing recommendations W3C: SOA SOA (XML, SOAP, ….), Semantic Web, Device indepence, multimodality, … IETF: Multimedia architecture (RTP, SIP, SDP, …), LDAP,.. Others Should incorporate emerging paradigms P2P, GRID, syndicated Blogs, Wikis, communities,..

5 Methodology The Reference Architecture should be properly validated in real implementations before adoption Like in IETF or W3C Several interoperable implementations should exist before adoption

6 Components Which ones should be defined and included? Only functions needed in real services should be included How do we select them? Probably by “user selection” among a rich variety of proposals progessed in IETF or W3C
