OpenDaylight Summit 2016

Blueprint is an OSGi compendium spec for a dependency injection framework designed specifically for use in an OSGi container. Blueprint is an alternative and potential replacement of the config subsytem (CSS) that is currently used in ODL for wiring and dependency injection. While powerful, the CSS has yielded obstacles and challenges with respect to in-place upgrades and developer usability. Using/converting to Blueprint alleviates these issues. In this session speakers will talk about the basics of blueprint and how to effectively utilize it in ODL, including various extensions that have been developed for ODL that make it easier and provide equivalent behavior as provided by the CSS. In addition, speakers will talk about how to convert existing applications from CSS to blueprint.
