OSGi: Blueprint vs. Spring DM

Question

I am a little bit confused about Blueprint and Spring DM:

From what I think is true:

• Spring DM is a framework defined by Spring Source
• B

Answer 1

In addition to what Dmytro Pishchukhin answered, it should be noted that the Spring DM project is somewhat a dead project, as DM 2 never reached a "release" version.

Instead it was contributed to the Eclipse foundation where it mutated into the Gemini Blueprint project.
