Appendix B. OSGi standard services

This appendix lists the Core, Compendium, and Enterprise services defined in release 4.2 of the OSGi specification. All services are optional: some are available from framework vendors, others are available from third-party vendors. Most service implementations work with any OSGi R4 framework.
