Interconnecting heterogeneous systems or applications
Making them communicate
Making them understand each other
Making them work together…

Physical interoperability (network interconnection)
Protocol interoperability (communication)
Syntax (messages) and semantic (interpretation) interoperability
Procedures interoperability

REMINDERS 2/X : FIRST NETWORK ARCHITECTURES
A
long time ago, systems were alone: one framework per company, no
communication from one company to another
 Then
the networks arrived, and the distributed architecture arrived too
 More applications
 Needs for consistency checks or for multi application (or multi databases) report
building
 Quickly,
a solution is found: federated architecture
 Heimbigner, D., McLeod, D.: A federated architecture for information management.
ACM Transactions on Office Information Systems (TOIS), Vol. 3, No. 3, p.253-278,
juillet 1985
 Case 1: use database synchronization tools
 Case 2: use federal database, filled from requests to other databases, usually readonly
 BUT: no reproductible & efficient process to build that, and usually read-only, and not
distributed

REMINDER 3/X: MEDIATION ARCHITECTURE
 Next
step: mediation architecture
 Wiederhold, G.: Mediators in the architecture of future information systems. IEEE
Computer Magazine, Vol. 25, No. 3, 3849, mars 1992
 The basic idea is to have adapters and mediators between applications
 Mediations may use ontologies to translate models from one application to another
 I3 Architecture (Hull, R., King, R.: Reference architecture for the intelligent integration
of information. Rapport technique (ARPA), 1995. http://ise.gmu.edu/I3_Arch/) is an
example of such architecture
 Coordination mediators accept queries and sequences them, translate them for other
mediators
 Management mediators discover dynamically new mediators, and configure them
 Semantic integration and transformation mediators translate from one ontology to another,
manipulates ontologies, split queries into many elementary queries that can be dispatched
to spetialized services
 Functionnal mediators are value added services
 Adapters ensure the connection to the applications and take care of physical, protocole
and syntaxic adaptation

REMINDER 4/X: OSI VS INTEROPERABILITY LAYERS
 OSI
(or IP) layers and Interoperability layers are not the same
 First
layers are common:
 Physical (Ethernet…)
 Protocol (IP, TCP or UDP, HTTP or FTP or …)
 Then
OSI continues with applications while Interoperability deals with
mediators

C2-SENSE
REMINDER 5/X: MULTI COMPANY IMPACT
 Today
issue is beyond multi application interoperability: it is multi
organization interoperability
 Networks are heterogeneous (not all IP based!)
 Networks are closed (for security concerns), then direct access to an application is
more difficult
 Use of DMZ for incoming messages/requests
 Use of proxies for outgoing requests, usually blocking all except the port 80
 Finding a common goal is also a matter or human relations (compared to a central
decision)
 Use
of HTTP based communications (SOAP, REST, …)
