Very interesting article by Peter Kriens of the OSGi Alliance. He explains cardinality, optionality and dynamic/static concepts in a dynamic platform such as OSGi.

He explains how the Declarative Services handled those issues and why he thinks the Spring OSGi initiative should follow the same rules.

He also mention that Spring OSGi is a candidate for Declarative Services replacement to be included in OSGi R5 spec.

This would be just amazing. I am a big Spring addict but the thing I like about Spring is IoC, and Spring is not the only IoC container around. I'm not very enthousiast about the idea of the OSGi R5 depending on Spring actually. I hope that the IoC implementation will be pluggable.

Finally, he feels like proxying (as pushed by the Spring OSGi working group) is not such a great idea and I don't feel that way, I hope that work in that direction with continue until either it works or we're very sure it's not possible. At least, it should be possible to be able to choose to work either with proxies or directly with service references.
