Other resources

COHORTE uses two main existing component models as underlying component-based software frameworks. If you are not yet familiar with iPOJO (Java programming) or iPOPO (Python programming) we encourage you to have a quick look to their respective web sites:

• Apache Felix iPOJO, a flexible and extensible service component model for Java developed by Clément Escoffier.
• Coderxpress iPOPO, a service-oriented component model (SOCM) framework for Python developed by Thomas Calment.

You need also to have a clear idea about the Service-Oriented Computing in general and OSGi specifications in particular.

• Service-Oriented Architecture: “Service-oriented architecture (SOA) is a software design and software architecture design pattern based on distinct pieces of software providing application functionality as services to other applications. This is known as service-orientation. It is independent of any vendor, product or technology.” (from Wikipedia)
• OSGi Specification: “OSGi technology is a set of specifications that defines a dynamic component system for Java. These specifications reduce software complexity by providing a modular architecture for large-scale distributed systems as well as small, embedded applications.” (from OSGi Foundation website)
