Choreography-centric SOA,
middleware and tooling
for Services and Things
 Why?
Need to support Future Internet (Internet of Services (IoS) and Internet of
Things (IoT)), Large Scale, Distribution in modern systems
 How?
 Enabling service choreographies definition and execution
 Introducing a specific Development Process and Integrated Development
and Runtime Environment (IDRE) for coordination of services through
choreographies

CHOReOS manages:
Major characteristics of Internet of Things
 High heterogeneity: totally different objects in terms of
functionality, technology and application fields that need to be
integrated
 Scalability: large number of “objects” (Pervasive technologies) that
need to communicate with each-other in a meaningful way
Major characteristic of Internet of Services
 Distributivity: numerous service orchestrations, dispatched over
the Internet, that need to communicate through message
exchanges, but avoiding a single point of control – or because a
single control point cannot be defined in a specific business
case!
Future Internet and CHOReOS

Orchestration vs. Choreography
Orchestration
Local
Centralized perspective
"Each player in the
orchestra strictly follows the
conductor's instructions“
Choreography
Global
Distributed perspective
“Dancers dance following a
general scenario, without a
single point of control”

No single conductor for choreographies
 CHOReOS provides the middleware that enables the execution of their
distributed coordination logic across different systems

 Context: Air transportation, Service to passengers
 Goal: Improvements in services, airport fluidity
 Scenario
 Bad weather at destination: flight rerouted to another airport
 Passenger stress, lack of information, delays everywhere
 Choreographies are introduced as part of an overall solution
 Leverage existing business processes (orchestrations) for
specific and local parts of the scenario, with well-known
orchestrators (e.g. air traffic control, airport authorities, airlines)
 Brings broad-spectrum choreographies and bridges between
disconnected areas of responsibility
Passenger-Friendly Airport Use Case

Use Case - Expected impact
Before CHOReOS
At alternate airport
 Delays everywhere (plane
logistics, handling
passengers luggage, …)
At airline level
 impervious dedicated
logistics for each situation
For passengers
 Poor indications
 Extra costs
 Waste of time
 … extra stress !
After CHOReOS
At alternate airport
 Less delays in rerouting-
consequences
At airline level
 Efficient coordinated logistics
 Costs reduction
 Improved flight rescheduling
process
For passengers
 Better information
 Less waste of time and money
 Improved airline/brand image

15
May 28th
, 2013
From BPMN2 Choreography Specification to (runtime
artifacts) Synthesis and (service) Discovery
Step 1: BPMN specification  model to model
transformation  choreography labelled state transition
systems (CLTS)
 Choreography global coordination logic specified by the CLTS
Step 2: Projecting the global coordination logic into
individual expected participant sub-CLTSs
 Expected participants behaviors
Step 3: Discovery of available services, generation of
Coordination Delegates (CDs), based on
actual behaviors + expected behaviors of services
 CDs will manage the services at runtime,
based on the choreography coordination logic
Choreography synthesis
Service-oriented
middleware

Why open source
Facilitates deployment of complex technologies
Lower barriers to access
Chosen licenses
IDRE development modules
 Eclipse Public Licence (EPL)
 Affero General Public License (AGPL)
IDRE runtime modules : Lesser General Public License

OW2 Consortium
''A global community working together to
develop open source infrastructure software**
and to foster a vibrant business ecosystem''
*Includes generic solutions in all product categories and middleware at large, including tools for the
development, deployment and management of distributed applications

The OW2 Future Internet Software
and Services initiative (FISSi)
 Joint efforts by OW2 Members aimed at
facilitating the use of OW2 FI technologies
(including CHOReOS) by mainstream
Systems Integrators, End-Users and
Software Vendors
 An opportunity: today's Internet shows its
limitations in the context of emerging and
pervasive mobile platforms, IoT becoming
a reality, a new world of Distributed
Systems of Systems
 The plan: provides our definition of Future
Internet, and solutions, as formalized in FISSi
 Participating Strategic Members: INRIA, Orange
Labs
CHOReOS as part of OW2 strategy

FISSi Targets One of Three FI Challenges
Networks and shared infrastructure
Services and applications
Media and content
In FISSi, CHOReOS will be the engine that
powers the very large scale interconnection of
smart data, objects and services

service choreographies
While Supporting Large Scale
Focusing on IoS and IoT
Middleware, tooling
E.g. usage of choreographies,
Coordination Delegates
The pursuit of the development,
valorization and business activities
beyond the original scope of the project
is enabled through the FISSi OW2
