8. Fractal in 5 minutes
• Started by
• Open Source, fractal.ow2.org
• Early ideas back in 2000

9. Fractal in 5 minutes
• It’s a Component Model
• Close to object-model (much more than EJB or
CCM)
• Very general, not-domain specific
• Everything is Fractal
•operative systems
•middleware
•services
•applications

10. Fractal in 5 minutes
• Java reference implementation (Julia)
• Many libraries (monitoring,communication
middlewares, deployment, transaction monitors,
general purpose components)
• Many tools (F4E, Fractal ADL, Fraclet, Explorer,
FScript, Juliac, FAC, Fractal BPC, BindingFactory,...)
• C reference implementation (Cecilia,Think)
• Other languages (c++, .Net, SmallTalk)

17. FraSCAti - Runtime
•Assembly Factory: Responsible for
processing SCA models
•Binding Factory: Import/Export SCA
components with specified
communication protocols
• Tinfi kernel: Generate SCA
components glue code and create
component instances
• Transaction: Manage local /
distributed transactions between SCA
components

18. FraSCAti contro Tutti
Reference implementation:
broader support to SCA specifications
Not very “agile”
Fork of Tuscany (same core)
Federation
Focus on OSGi+JNI
