Distributed Collaborative Systems Distributed Data Management Computer Supported Collaborative Work

Service Oriented Computing BPM (flexibility, user centred) Service composition Non Functional Aspects (Transaction,

Security) Engineering

Methodological foundations

System design and development Formal validation Experimental and Empirical Studies

Distributed Collaborative Systems

How to support people working together but distributed in time, space and organisations

Requires expertise in Distributed systems (data and services are

everywhere) CSCW (users are involved)

Our vision : Collaborate without a central authority Better acceptance Better reliability Allow to apply different policies

Consequences

P2P settings Data are shared but everybody keeps a

copy and control on the copy E.g. Distributed VCS

Distributed process orchestration Push orchestration near the service

provider Control data flow among partners

CSCW

Questions about support for collaborating teams and their coordination Implicit : knowing what the other are doing is

sufficient to coordinate (workspace awareness) Explicit : coordination has to be modelled and

enforced (process) Important issues

How to detect conflicts How to solve conflicts How to avoid conflicts How to respect privacy

Service Oriented Computing

Development of applications at the scale of the web

How to develop services that are Efficient, Safe, Secure, Flexible, Adaptative

How to ensure/enforce some properties on service composition Transactional properties, Security

properties, Privacy/Quality of service

BPM

Two main problems Inter-organisational processes Flexible Human Driven processes

Inter-organisational processes Distribution of execution and control

Flexible process Bonita WFMS Crisis Management support

Perspectives : Scaling up

Identify and manage collaboration and service at a new scale From group to communities From people and organisations to social networks Without a central authority

Requires New paradigm for security (Trust ?) New paradigm for coordination ?

Uses cases Crisis management Production of international scientific report (climate report) Crowd Sourcing ...
