At this moment the Native OSGi refers to Executions Environments as a possible solution, in that case a bundle would be for a specific platform, and the execution environment would be a requirement for the platform. In our opinion this is a better match, the bundles are kept small (interesting for embedding) and platform specific (easier to add a different platform for a component as new bundle later), the environment declares what platform. (where platform can be a combination of information which still has to be properly defined, eg architecture, libc, etc). > > Either that or adding the corresponding Require-Capability header > > Also worth a mention, there might be other Req-Cap's needed: for example > one for the c library version.

IMHO Req-Cap specify additional dependencies/relations between bundles, not from bundles to the environment. Having said that, I might be wrong, and perhaps with a different view Req-Cap can as well be usable for the environment, so feel free to elaborate and shoot at this :). -- Met vriendelijke groet, Alexander Broekhuis
